THIS ARTICLE HAS A SPONSOR: If you haven’t yet talked to Nick Hopwood, our PEAK LOGOMGoFinancial Planner from Peak Wealth Management, this might be a good week to catch him, since Nick reports he has barred himself in his office and plans to do nothing but work until all the Spartans in his life think he’s run off to live a simpler life in the woods or something.

Our deal is Nick is the guy I go to for financial strategies, and he gets to ask us Michigan questions on your behalf. Anytime it’s a Nick question, we’ll let you know. Anytime you’ve got a financial question, let Nick know.

Michigan ran a few zone read-like things with O’Korn but for whatever reason these just got a back swarmed for no gain. [Bryan Fuller]


Nick’s Question:

MGoBlog: Do you have a question this week?

Nick: f---?

MGoBlog: That question is self-answering. New question.

Nick: sigh.


Nick: How does this offense get better?

MGoBlog: Yelling at it?

Nick: I mean that’s my question. You have to answer it.

MGoBlog: Yell at it LOUDER.

How does this offense get better?

Seth: Let's start with the simplest: build some quarterback running plays into the offense because O'Korn is a better run threat than a Tom Brady-esque check-to-your-5th-read distribution center. Also the pocket won't last that long. If the ends are constantly having to worry about holding the edge or getting optioned that takes some pressure off the tackles. And I think they are starting to build an interior running game that's functional as long as the counters are.

I thought I saw O'Korn mess up a couple of zone reads in this game and then Michigan dropped it but the Denard power offense might be a good fit for these guys if they could find a running back willing to lead block.

An onlooker or two literally fainting at something Gary does
this spring would be nice. [Bryan Fuller]

Our annual rite. The Question:

What do you want to hear out of spring practice?


Adam: There's depth on the D-line. Not "there are humans and they are large and they have played football before so yes, they are football players" depth. I'm looking for reports gushing about how much the backups have developed.

We've seen this a bit with Michael Dwumfour in last season's bowl practices. That assuages fears about NT depth a bit; Mone still has to stay healthy for a full season, but at least five-star Aubrey Solomon is available and, if his high-school highlights are any indication, ready to enter the rotation.

Every other spot on the line, though, is returning a starter with a fair bit of on-field experience and really unproven backups. Rashan Gary will start at SDE/Anchor, but he'll need Carlo Kemp or Donovan Jeter to spell him. Mo Hurst is the best 3Tech in the conference; positional nomad Lawrence Marshall or true freshmen James Hudson and Deron Irving-Bey are ostensibly his backups. Chase Winovich got to live out his dream and actually chase things down last fall, and if Don Brown's effusive practice reports are any indication then he should continue to do so this fall. There's a veritable stable of options behind him in Reuben Jones, Ron Johnson, Corey Malone-Hatcher, Luiji Vilain, and Kwity Paye; this group has a combined four games of collegiate playing experience. There's a ton of talent along the line, but it still has to be cultivated if Greg Mattison is going to have the eight-man rotation he prefers.

Kemp has been around long enough now that we have a photo of him in the old jerseys. It’s time for one of those guys to emerge. [Fuller]


Ace: Charles Matthews is hitting his jump shots. Wait. Shit.

/reaches over to Acebot
/flips switch


Ace: Okay, Cesar Ruiz is on track. With the depth at tackle in its current state, Michigan needs interior linemen to step up so there’s at least the option of shifting someone (probably Mason Cole) to tackle to get their best five out there. While there are a couple other bullets in the chamber in Jon Runyan Jr. and Stephen Spanellis, freshman Cesar Ruiz seems like the best bet to crack the starting lineup, whether at center or guard. He’s far from your average true freshman interior lineman: he played center, not tackle like most D-I OL prospects, at IMG Academy, so he’s already acclimated to playing on the interior. He was consistently talked up as the best interior lineman at the Under Armour All-American game. He’s got the build at 6’3, 320. Michigan doesn’t need him to be the star this year that he should become; it’ll be encouraging to hear that he’s on track.

[This is a work-in-progress glossary of football concepts we tend to talk about in these pages. Previously:

Offensive concepts: Run-pass options (RPOs), High-low passing routes, Covered/Ineligible receivers, Blocking: Reach, Kickout, Wham

Defensive concepts: Keeping Contain/Lane Integrity, Force Player, Hybrid Space Player, One-Gap Fronts, Scrape Exchange. Coverages: Tampa 2, Pattern-Matching, Quarters and how MSU runs it

Special Teams: Spread punt vs NFL-style]


Depending who you ask there are either two or three or sixteen thousand different blocking schemes offenses use to puncture run lanes into a defense. If we cut out a few exceptions, and a lot of variants, you can boil them down to two basic philosophic schools: Zone and Gap.

(And man, and hybrid, and zone can be split between outside/inside but shut up).

Harbaugh, as you might have heard, is one of if not the ur gap coach in football, as is his top lieutenant Tim Drevno. New tackles/tight ends coach Greg Frey, as we’ve mentioned twice this week, is not just in the zone camp but is one of the chief practitioners of its outside zone wing.

What’s the difference, and why does it matter? I’ll show.


“When badly outnumbered he managed, by swift marching and maneuvering, to throw the mass of his army against portion of the enemy's, thus being stronger at the decisive point.” –description of Napoleon battle tactic

This is the football’s fastball: I’m coming towards the plate so fast and so hard that by the time you know where it’s going you can’t catch up. To use a war metaphor, gap philosophy is about picking a spot in your opponent’s defenses, puncturing a hole, and sending as much material into it as possible as quickly as possible before the defenders can match it.


The above formation is unbalanced, which did its job in getting the defense to leave a cornerback and safety to a side with zero receiving threats (Mags is ineligible by number). The fullback has a kickout block on the SAM linebacker. Kalis pulls, Asiasi picks off a linebacker, and Deveon Smith gets a 300-pound escort through the gap between Wheatley and the back of Khalid Hill. That gap is the gap they planned to attack, and the most likely one to become available.

That it won’t always be available is what makes gap blocking go from very simple to highly complicated. The great power teams know how to adjust on the fly to defenders diving into the important gap, for example on this play if the SAM is coming inside hard Hill might arc outside on the fly, seal the SAM inside, and hope Smith and Kalis adjust to earn a big run. Or what if that Mike linebacker blitzes the gap inside of Wheatley? Or the whole dang defensive line slants playside? In general the OL will do their best to not let that happen and adjust (e.g. Asiasi might have to assist Wheatley, or the puller might kick out an unblocked end discovered at the point of attack).

I think you get the gist. Gap blocking has everybody working to widen the chosen gap and get bodies attacking that gap as soon as possible. Emphasis is on overpowering—as you see here this play works mostly because Ty Wheatley Jr. latched onto the playside defensive end, and rode him downfield.

The question:

So, next year’s offensive line/defensive line…any conce…why did you just run under the bed?

Seth: I ask this because I was playing with a depth chart for next year and I'm kind of more worried about DT than OT.

Ace: It’s an understandable concern, especially now that it looks more likely Michigan could whiff on Solomon/Tufele/Reitmaier. While I’m still more worried about the offensive line, the lack of depth after Mo Hurst and Bryan Mone—who hasn’t been able to stay healthy for anywhere close to a full season—is worrisome. A couple freshmen are going to get pressed into service early.

Seth: That's the thing: there aren't a lot of bullets in that chamber.

Ace: With the number of SDE/5-tech types Michigan is bringing in this class (Hudson, Jeter, Irving-Bey), I wouldn’t be surprised if Rashan Gary slides inside to help out with that.

In related news, it’d be really nice if Lawrence Marshall finally broke through.

Seth: I figure the starting four are locked: Gary at SDE (anchor), Hurst at DT, Mone at NT, Winovich at End. For passing downs they go with a 30 front, pulling Mone and having Gary and Hurst slide down. The top DL backup then is your backup anchor: Kemp, Reuben Jones, Marshall, whoever, who comes in for Gary when Gary is in for Hurst who may be in for Mone. But then Mone hasn't stayed healthy for a year yet. And if you lose any of them we're down to....Dwumfour?


[Aaron Bills]

Garrett Miller?


Ace: Paea is the least college-ready of the incoming DTs; I still like him more at guard, to be honest. I think Dwumfour and Hudson are the best bets for those backup spots if Michigan can’t land Tufele. Practice reports from the Army Bowl have been pretty positive for Irving-Bey, as well, so perhaps he could get into the rotation.

Mone’s health is paramount, which is rather terrifying.

Seth: Yeah, none of those guys are likely going to be ready to play nose, and that would be a colossal waste of Hurst.

Ace: I don’t see many scenarios in which Hurst doesn’t see a fair amount of time at nose, unfortunately. He should be much better at it next year than he was in 2015, though.

Seth: The playbook has Hurst-style nose tricks, and I agree 305-pound senior Hurst >>> 275-pound sophomore Hurst. But when you put a guy with his skills over the center and leave him to doubles forever those glorious plays when he's in the backfield before the quarterback has pulled up his read buttons disappear.

Ace: You can still slide Gary inside on those snaps, insert one of the young guys at SDE, and have a pretty decent line out there, though.

Adam Schnepp September 23rd, 2016 at 10:00 AM



Talk about the line play through three games. Some room for improvement, do you think?

“Yeah, absolutely. There’s always room for improvement. They’ve done a good job and we’ve got to keep on getting better just in pass protection, which is—we’ll do that, and communication. But they’ve done a nice job, and we expect a big game this week.”

Do you see guys still playing too high at times?

“Yeah. You always can improve on the offensive line with pad level. You’ve got to get lower and get your eyes in the right spot and be physical with your hands and move your feet and know where you’re going and communication and targets and that sort of thing still needs improvement. Every day you’ve got to work on that and that’s important.”

Do you still see a rotation with the two Bens at left guard?

“Rotation’s always open. Rotation’s always open.”

Talk about Bredeson’s progression.

“Done a nice job. Really has. He plays, like I mentioned before, quick twitch and smart and can process quickly on his feet. Like all those other freshmen, has done a nice job transitioning there and really improved.”

What did Wilton show you in that game? You take the first game interception and then the big hit and coming back in.

“Wilton’s a true competitor and he’s a tough guy. I think anybody who plays the quarterback position’s got to be a tough guy. You’re gonna take hits you don’t want to happen, we don’t want to happen, but it’s how they respond. I mean, that was a tough hit on him and he bounced up and he led us the rest of the game and took us back from being behind. Just really pleased with what he did. It shows his true character and how important it is, the team to him and him being a competitor and winning every down.”

Depth Chart

LT Yr. LG Yr. C Yr. RG Yr. RT Yr.
Ben Bredeson Fr. Ben Braden Sr.* Mason Cole Jr. Kyle Kalis Sr.* Erik Magnuson Sr.*
Grant Newsome So. David Dawson Jr.* Patrick Kugler Jr.* Michael Onwenu Fr. Nolan Ulizio Fr.*

Michigan's line took a quantum leap in 2014, going from a flaccid crew of confused gibbons to pleasingly mediocre. Last year's edition of this post positively marveled at the fact that these gentlemen got in the way of the opposition frequently enough to be average-ish:

It got better. It really did. The OL nadir is in the past. We can come out of the bunker and rebuild society now.

That assertion was based both on my charting and a bunch of stats, many of them of the advanced line variety. Advanced line stats make total guesses about assigning credit and blame between tailback and line but they're worth peeking at in case they tell a story. Michigan's 2015 stats are mostly about treading water:

Year Adj Line Yards Opportunity Rate Power Success Stuff Rate Adj Sack Rate
2013 118th 11th 120th 126th 112th
2014 50th 55th 32nd 67th 72nd
2015 53rd 107th 50th 33rd 13th

Michigan was less likely to get tackled for loss and less likely to get the 5+ yard carries that opportunity rate tracks. Those were a wash as Michigan's line yards stayed static. Contrary to your memories of the OSU game, pass protection took a big leap forward.

A certain level of treading water is expected when a new coach with a new, complicated system arrives. With four starters back and Mason Cole moving to his natural position, a step forward is likely. It's just that fifth guy who gives pause…

An Editor's Note About Charts

With four returning starters you're going to see a bunch of charts derived from last year's UFRs. Here's how to read them:

Game Opponent + - TOT Pass - Error Rate Comment
1 Utah 5 8 -3 5 8% Guy did X

Game and opponent are self-explanatory. The +, –, and TOT columns are my evaluations of how the player did when run blocking. Keep in mind that zero is not good, or even average. It is the nature of the beast that any successful run has many successful blocks; many unsuccessful ones are submarined by a single error. We're looking for a 2:1 positive-negative ratio to be decently successful. A future pro might be more like 3:1 or 4:1.

"Pass –" is derived from the protection minuses in UFR.  Two protection minuses are approximately equivalent to one sack or severe hurry. "Error rate" is the number of protection minuses divided by the number of available protection points. The above line is Ben Braden's from the Utah game, in which he was almost 1:2 in run plus/minus and had protection errors on 8% of snaps. That's terrible; the good news is that Braden got better.




present, he said [Brian Fuller]

Senior ERIK MAGNUSON was thrust into the lineup too early as one the umpteen guys tossed into the maelstrom of the 2013 offensive line. He was a guard then; the next year he played some there and, after an injury cost him his job, as a blocking tight end. Last year he got flipped out to tackle.

There he... well, he was there. He was neither forceful nor overrun. He didn't shut down elite pass rushers or get blown through by mediocre ones. His UFR chart from last year is decidedly sparse when compared to Cole's:

Game Opponent + - TOT Pass- Error Rate Comment
1 Utah 2.5   2.5 2 3% Hooray?
2 Oregon State 5 0.5 4.5 0 0% Not as involved as others but got his job done.
3 UNLV 6   6 0 0% Clean positive sweep from the OL.
4 BYU 2.5 3 -0.5 0 0% M clearly left-handed when it wants to rely on tackles.
5 Maryland 4 4 0 2 4% Clear left handed bias again.
6 Northwestern 6.5 1 5.5 4 10% End of game was pretty.
7 MSU 3 2 1 3 7% A little frustrated with his second level blocking.
8 Minnesota 5 1.5 3.5 1 2% Good day for him although M is clearly left-handed.
9 Rutgers 3 4.5 -1.5 0 0% Not real good on perimeter.
10 Indiana 6 4 2 2 2% Did okay.
11 PSU 3   3 4 6% Also took advantage of weak edge.
12 OSU 3 2 1 5 8% See Kalis.
13 Florida 5.5 6.5 -1 1 2% Iffy game.
  TOTALS 55 29 26 24 4% 65% run blocking

It's not so much that Magnuson didn't execute, it's that he wasn't called on to do much. He's right around our run-blocking Mendoza line thanks to some good days against the overmatched bit of the nonconference schedule. 24 pass protection minuses over the course of a season isn't anything to write home about, but Cole's maturation and Magnuson's move to tackle are the top two reasons Michigan's pass blocking got a lot better a year ago. When I started to talk about the OL individually in the middle of last year this was the conclusion:

Magnuson is [just a guy] right now. He's okay at blocking. They don't run to him very much. There are not many plays on which he has a big role and that seems to be about half Cole and half Magnuson. He is the Jarrod Wilson of the offensive line.

He's boring. We appreciate this immensely, because we are well aware of the alternatives to boring after the past half-decade.

It's maybe a little disappointing that Magnuson seems to be topping out at boring. I usually pick out the particularly good or bad plays to embed in these previews; Magnuson doesn't have anything to embed either way. On the ground I had him for zero +2 blocks a year ago and one –2 block. Part of the reason he doesn't have a lot of magnitude in that chart above is that he usually does something completely adequate and not that notable. When he does score a plus it's frequently for excellent awareness. Here he reads a blitz and manages to redirect enough to hit the linebacker who would otherwise be burying Smith in the backfield:

When Magnuson does move a guy it's usually because the guy is already moving. He was good at reading and staying attached on slants in Michigan's zone game; a bunch of cutbacks opened up last year because he was able to shove a guy past his intended destination.

This is a power play but it's the same principle and from a camera angle that makes it very clear:

The other times Magnuson moves a guy is because he's already engaged with Kalis:

Magnuson was effective at doubling a guy and popping out to the second level.

These are all real assets.  They are offset by what I described as a "lack of oomph" after the Indiana game. Magnuson is not likely to get drive in a one-on-one block, and occasionally he ends up looking a bit… finesse.

That play was an outlier but I don't have anything in the way of a one-on-one drive block in an entire season of clips. This is an area he should get incrementally better in since he's got another year of weight training behind him; the time for big leaps forward is likely past.

Not everyone is as indifferent as this space was. CBS NFL draft analyst Dane Brugler called him a "legitimate NFL prospect" and "one of the top ten senior offensive tackles in the country."

...moves with a smooth shuffle and wide base, transferring his weight well in his kickslide to mirror edge rushers. He stays low off the snap and prefers to use his hands to control the point of attack to out-leverage and out-power defenders. Magnuson is able to secure downblocks and anchor at shallow depth, driving his legs to finish in the Wolverines' power offense.

I disagree with this take, but it's out there.'s Chad Reuter told Mike Spath that Magnuson could work his way into the first or second round with a good 2016; I disagree with that take as well… but it's out there.

Magnuson was relatively advanced mentally a year ago and will benefit less than some of his compatriots from increasing familiarity with the offense. Improvement should be clear but not transformative; a good goal is for Magnuson to move beyond Just A Guy status, get on the All Big Ten team in a very down year for the tackle spot conference-wide, and get drafted late.

Seth January 6th, 2016 at 10:00 AM

How does a mediocre running team do this:

…to one of the best run defenses in the country? Let's discuss.

Entering this game Florida was fifth in rush D to S&P+, giving up just 4.4 YPC with sacks removed, which means they turned their opponents' running games into basically Florida's freshman-infested running game. In our diagram for Ace's FFFF we gave 7/11 defensive starters a "dangerman" star, and three(!) got the shield that's reserved for the top players at their position in the country. Among them was end Jonathan Bullard, perhaps the best run-defending player in the nation, and strong safety Marcus Maye.

And yet Michigan, whose running game was barely better than Florida's this year, ran on that: 225 yards on 46 carries. Brian mentioned in the game column that a lot of this came from a reinvigorated De'Veon Smith, and from my rewatch I bet you the UFR will bear that out. There was also a little RPS, some great plays by individual offensive linemen (Mason Cole and Graham Glasgow had very good games), and some Harbaugh games.

Part I: Florida throws paper

The run above, which came mid-way through the 2nd quarter, must be taken in context. Smith by this point was already well up in +'s running Michigan's base stuff, and Rudock was well on his way to an excellent day.

Florida's pass defense is just as good as their run D, and in passing downs they're lethal. So it's worth it to them to try some surprising/a little unsound things on 1st and 2nd down to keep Michigan's offense behind schedule, and bring up those long situations. Against Michigan in particular it appeared Florida's gameplan was to take away inside runs, trusting the Wolverine backs not to find any holes that left elsewhere.

Let's first go back to an earlier thing Florida did that should have earned a TFL:

This is the one where the broadcast crew infamously put up the ND and OSU scores mid-play. What Florida called (I think) is below:


It's an under but the 5-tech is actually in a 7-tech.

Michigan tried to run "Power" into this, pulling Kalis, blocking down on the DL and using the fullback as lead blocker. Florida is ready, as the NT shoots up the back of Glasgow before Braden can get an angle on him; Braden blocks air, and Kalis runs into the nose in the middle of his pull:


Smith did a very good job to dance around that NT, then to bounce outside the unblocked MLB whom Kalis was heading toward, turning minus two yards into four.

The lesson: Florida was messing with Michigan's power running attack by sending rushers into the A gaps, leaving the 'B' gaps open, but only as a funnel directly to the linebackers. Yes, you'd like Braden to get a better block. Yes, that was a great play by the NT to get into the path of Kalis. But this was Florida's plan against Michigan's base thing, and they got the base thing. RPS'd.

It got better. It really did. The OL nadir is in the past. We can come out of the bunker and rebuild society now. 

By any reasonable metric it in fact got a lot better. Michigan's YPC leapt 1.3 yards, going from 11th in a 12-team league to 8th in a 14-team one. If you only look at Big Ten stats Michigan is still 8th, and that's in the division that had the MSU, OSU, and PSU defenses. Sacks allowed had a near-identical improvement, going from barely better than Purdue to a spot in the respectable midsection of the conference. Advanced stats saw something similar. Michigan finished 50th in adjusted line yards*, 32nd in power success rate, and 72nd in adjusted sack rate. And that's with the running backs going the wrong direction constantly.

None of these numbers stand out, but neither do they linger in the seedy parts of the list next to Temple and Penn State and Louisiana-Monroe. They were average-ish. Most of the time they felt average-ish.

That's not a bad place to be with zero seniors and just two upperclassmen. While the unexpected departure of Jack Miller puts a small dent in the front's depth, his likely replacement, Erik Magnuson, is a redshirt junior who came in as a touted recruit and has a season's worth of starts to his name already. If you're willing to fudge a bit, Michigan has five starters back from that okay line. They've replaced Brady Hoke with Jim Harbaugh and Darrell Funk with Tim Drevno.

Could they be… good?

Cole coped [Eric Upchurch]

Rating: 3 of 5

Last year I gave this a 1 because Michigan was staring down a starting lineup consisting of a true freshman and a third-year guy who didn't even get a sniff during the chaos of 2013. They seemed to acquire these positions almost by default since the only other tackles on the roster were freshmen (redshirt or true) regarded as huge projects. Or they were starting at guard.

The 2014 edition of this post took a quick gander at what happened when football teams started freshman tackles. It was almost universally ugly. The best case scenario was Ole Miss, which deployed ultra-blue-chip Laremy Tunsil as a true freshman and was middling in both YPC and sacks allowed. All others trundled their way to seasons that were more or less disastrous.

Michigan was not disastrous last year. In what is certainly a first for offensive line projections in recent history, that prediction was pessimistic. MASON COLE, the true freshman, just about hit the top end of reasonable projections, those being:

The occasional freshman tackle can cope. I think Cole is one of those guys. But is he going to blow a guy off the ball and provide a big ol' lane at 292 pounds? Probably not. Our hope here is that Cole is a solid, agile pass protector in year one who is a meh run blocker.

Mason Cole coped. This is what that looks like in the run game according to UFR:

Opponent + - TOT Notes
App St 9.5 2 7.5 A fine debut
Notre Dame 4 2 2 Didn't seem overwhelmed at all.
Miami 8 5 3 Okay; also had one very bad pass pro.
Utah 3 2.5 0.5 Nice seal block ignored.
Rutgers 5 5 0 I'll take it.
Penn State 1.5 5 -3.5 Hull and Zettel bad matchup.
Minnesota 4.5 2.5 2 Overpowered a little but still okay day.
MSU 1.5 2 -0.5  
Indiana 3 0.5 2.5 Didn't mess anything up.

It was rougher in pass protection, where I have had him for 16 protection minuses in 8 games. Those are worth about half a QB pressure/sack each. Otherwise things were pretty okay against non-elite defenses. Cole's debut season was… eh.

When it didn't go well, the usual reason was that Cole got blown backwards because he was a true freshman. These were the kind of things that were happening against Zettel and company:

This was a game in which Cole's inexperience and lack of big skrongness really hurt. Here Butt gets an excellent shoulder spear on Zettel, knocking him off balance. This should provide ample opportunity for Cole to step around and wall Zettel off, creating a crease Smith will hit trying to beat a safety for a big gainer. Instead Zettel comprehensively wins:

Cole got whipped on the Norfleet catch that put Michigan in position for the winning field goal; Michigan was fortunate that ball went to the WR instead of getting knocked anywhere.

Ennui prevented me from charting him against Joey Bosa, but I've gone back and rewatched the OSU game. Cole was okay. By the second half of The Game Ohio State decided that they should either blitz outside of Bosa and send him against the interior line (which only kind of worked) or have him go at Ben Braden (which very much worked). Don't get me wrong, Cole did get beat. It was a struggle; it was not one in which he was completely overwhelmed.

All of that is terrific for a true freshman. Cole grabbed the job, held the job all season, and played reasonably well. There has been not a whisper that he would go anywhere except for a blip during spring practice when he was playing center, that because Glasgow was suspended and Michigan was figuring out if he could play there a la Barrett Jones. All practice reports have held that he is a sure thing, greatly improved, etc. 247 heard this from multiple people in a 24-hour window:

Mason Cole has unsurprisingly established himself as a rock at the left tackle spot, and is primed to be the next great four-year starter to play the position.

Cole's added 13 pounds and should make a major leap in year two, what with the rare true-freshman-to-true-sophomore OL transition coupled with the general HARBAUGH.

That will probably still leave him short of dominant. Michigan's most recent really good left tackle, Taylor Lewan, took off in his third year. In year two Cole should slash the protection issues considerably and do okay against the better defensive ends in the league. A year like early Graham Glasgow—reliable, somewhat short on raw power—would set Cole up to be excellent as an upperclassman.

While I was chatting with Brian last week he happened to pull up the top 7 composite recruits from the 2013 season. I followed and…


Woof. Green has obvious vision problems and hasn't emerged from a pile of guys among whom the most statistically effective last year was Drake Johnson. Dymonte Thomas and Shane Morris are already juniors and to date still seem to be at least a year's worth of good coaching away from ready.

That leaves us the offensive line class. Kugler seems to be on track to start when Glasgow surrenders his job—I've heard the same suite of nice things you have. Bosch transferred after performing about how you'd expect a true freshman thrust into a Borges-coached OL would. Fox hasn't been mentioned since a staff ago. Dawson we have only a little more data, much of that getting owned by Maurice Hurst in the spring game (if Hurst does that against Utah's OL I'll happily rescind that as a criticism).

On the other hand we caution all the time about giving up on OL when they're too young.

So when do you know about an offensive lineman?

This is a question I've been interested in a long time, going back to an article one of my Daily colleagues did on OL recruiting to highlight the injuries plaguing the classes Michigan took while I was there. I could never find the article but in January 2013 I tried to recreate some of that information, plus a 12-year update. I did a thing about a year ago on growth tracks to reset expectations for those 2012 and 2013 line classes. Let's check in again, this time with columns.

OL growth chart

The towers shrink because players currently on the roster are included in the data, and obviously our information on them is incomplete. "Not available" is a catch-all for transfers, dismissals, guys playing defense, injuries and medicals and whatnot. "Excellent" is basically all-conference-ish, "Solid" is that, "Liability" are guys who were starting but the fan consensus was they shouldn't be or wouldn't but for things like the 2008 depth chart or gross Borges incompetence.

This time I differentiated between "backups" and "two-deep" (an imperfect thing from memory and pouring through old Wolverine annuals). The former are guys buried on the depth chart and unlikely to play; the latter are only the top backups we are relatively certain would have played if they weren't behind an established starter. It's not about being technically on the two-deep, more like the first one or two guys in if an OL goes down—Erik Magnusson last year, or Leo Henige forever.


  • Redshirting is overwhelmingly the normal thing to do as a freshman.
  • Only a handful of players are capable of starting (shades of yellow) as redshirt freshmen. If you take the yellow chunk from there and size it against the 4th and 5th years you can see only about a third of the eventually useful players are demonstrably so at that age. Sing the praises of any 2014s already playing; don't give up on any who are not.
  • By RS Soph there is a big yellow expansion. The mysterious "backups" region has shrunk considerably. You have a fairly good sense of who these guys are by the end of this year.
  • There is very little difference—just a slight improvement—between RS Juniors and 5th year seniors. The backups disappear into unrenewed 5ths.

If you're using this imperfect data set of 82 players, many of whom didn't complete their careers for non-ability-related reasons, to get a feel for when to judge an offensive linemen, you could say it's a half-life. Don't judge a (redshirt) freshman unless he's already playing well, but after their third year in the program if he's not on the two-deep the chances of ever doing so decrease exponentially.

What this means for the 2012-'14 OL classes

Be excited for: Mason Cole.

Be extremely content with: Mags, Kalis and Braden if they seem to be playing well this year.

Keep an eye out for: Kugler, Logan Tuley-Tillman, and David Dawson. These are 2013 guys mentioned as probable two-deep contributors, though our current scouting has Kugler pretty much ready to play, LTT half-way there, and Dawson probably not ready yet. Further data received on them this year will speak volumes about their futures.

Be patient with: Juwann Bushell-Beatty. If he pops up this year he's probably going to be awesome; if he's buried there's plenty of time that this doesn't matter.

Getting late: Bars, Fox, Samuelson. With Bars at least we've heard past mentions of him competing, though he was always kind of the last guy in that 2012 class. He may be on the Huyge track; if he's not on the two-deep this (his redshirt junior) year it doesn't seem very likely he'll be a starter in 2016. Fox has been hurt so much in his career (just going off of game reports) if he's not medicaled he probably deserves some extra time to get caught up. Samuelson I've heard nothing about; even when I ask people with insider-y info I get nothing.


Hello: Tim Drevno, Offensive Coordinator

Hello: Tim Drevno, Offensive Coordinator Comment Count

Brian January 16th, 2015 at 11:40 AM

Previously: Ty Wheatley (RBs), Jedd Fisch (WRs), Greg Jackson (DBs), John Baxter (ST).


If you like manball there's no better guy to have as your offensive coordinator than Tim Drevno. As both a TE coach and OL coach, he was one of the main architects of the thumping Stanford lines that brought the Cardinal to their recently-elevated level. Afterwards Drevno transitioned to the NFL and got a plum job at USC. Now he rejoins Jim Harbaugh at Michigan.

After a small-school tenure as an offensive lineman, Drevno's coaching career started with a few years coaching TEs and RBs at smaller schools. In 1999 he transitioned to OL at San Jose State. Since then he's been exclusively an OL coach save for his first two years at Stanford, when he handled TEs. He also held the offensive coordinator title for Harbaugh's extremely successful San Diego teams. (Harbaugh in fact inherited Drevno from the previous administration.)

At Stanford, Drevno was a key part of the machine that actually got up and running in Harbaugh year two:

[Ranking out of about 120]

YEAR TEAM DREVNO Rush S&P Overall S&P Main back(s) Results
2006 Stanford N/A 105 113 Kimble
220 rushes, 900 yards,3.8 YPC
2007 Stanford TE 37 83 Kimble
280 rushes, 1150 yards, 4.1 YPC
2008 Stanford TE 6 31 Gerhart
330 rushes, 1850 yards, 5.6 YPC
2009 Stanford OL 12 6 Gerhart 340 rushes, 1870 yards, 5.5 YPC
2010 Stanford OL 30 3 Taylor
370 rushes, 1800 yards, 4.9YPC
2011 Stanford N/A 18 8 Taylor
370 rushes,2100 yards, 5.6 YPC

It's hard to separate Drevno out from the general Harbaugh effect, but again the continued success of Stanford after coach X's departure bodes very well in this case. This wasn't Texas or Alabama when they were up and running. This was a program transformation that stuck; that Stanford continued to excel after Drevno left is pretty good since he was one of the major molders of guys like David DeCastro and Jonathan Martin.

Drevno went with Harbaugh to San Francisco, where he was the OL coach; oddly, NFL veteran Mike Solari was also the OL coach. The two guys had the same title. In any case, the San Francisco OL was up and down.

[rankings out of 32 teams]

YEAR TEAM Rush DVOA Line Yards Power Success Adj Sack Rate
2010 San Francisco 17 13 23 30
2011 San Francisco 24 21 29 25
2012 San Francisco 3 1 12 29
2013 San Francisco 14 29 28 22
2014 San Francisco 8 10 32 30

After a step back in year one, the 49ers had a terrific rushing offense in year two; they then took a major step back. At no point was their sack rate anything other than bad, but he did inherit that and quarterbacks do have a significant, often-unacknowledged hand in that. Kaepernick is a guy who prefers to extend plays even if that results in additional sacks because when it doesn't he frequently lopes downfield for thirty yards.

Despite those numbers, San Francisco sent two OL to the Pro Bowl in 2013 and had their entire line named as either a starter or an alternate in 2012. Margins in the NFL are razor thin.


L to R: true FR, redshirt FR, junior, true FR, redshirt SO

Last year, Drevno returned to college at USC, picking up a run game coordinator title and inheriting a line that thinks last year's Michigan line is impressively experienced. Three true freshman saw extensive time, with Toa Lobendahn moving to left tackle midseason when sophomore Chad Wheeler went down with injury. Redshirt sophomore Zach Banner moved into the starting RT job; Max Tuerk was the only upperclassman, and even he ended up moving to center.

This is like last year's Michigan line if you replaced the starting guards with freshmen instead of a redshirt junior and redshirt sophomore.


Despite that, the numbers were middling:

Offense Adj. LY Rk Opp. Rate Rk Power Success Rate Rk Adj Sack Rate Rk
USC 104.4 54 38% 76 62% 104 107.9 56

USC was about average in line yards and adjusted sacks, a bit below that in "opportunity rate"—the percentage of run plays that go for five yards—and bad at short yardage. Top USC back Javorius Allen almost hit 1500 yards at 5.4 a carry. That's impressive for what must have been one of the youngest lines in the country.


Drevno has extensive Harbaugh experience and did very well considering the situation in his single year at USC; he was one of the primary guys driving the Stanford rushing renaissance whether it was as a TE coach or an OL coach. A lack of OC experience is not a problem since Harbaugh has a major role in coordinating his own offense, and Drevno worked with Harbaugh in that capacity at San Diego.

At 45, he's probably looking at this job as an opportunity to impress and get a head job. Given the history there that's not exactly a longshot.


Ain't no more upshot.
