Michigan's run game started out with a thud, with a series of short gains and even the occasional Dread Pirate TFL rearing its ugly head. As with the Notre Dame game, the problems due to were a mélange of errors from lots of people. And as you might expect against Miami, most of them were mental issues.
People have asserted that Miami was dropping an eighth guy in the box and that guy was blowing up the Michigan run game. That's simplistic; these days spread-oriented offenses are looking at one or zero deep safeties on every play. The eight man box is something you have to deal with as a coach, and anyway when you're playing Miami it shouldn't matter.
Michigan's issues were largely assignment-based, with the occasional bad block thrown in; the tailbacks were better but still had issues. The nice thing is that as the game went along we saw Michigan correct some of those those problems and start moving forward. Mason Cole in particular was evolving right on the field, hampering two plays with errors and then executing in near-identical situations just a few minutes later. One was mostly executing a block; this one was about IDing the guy he needs to address.
Which Guy Needs Help? Not That One.
This is actually the first play of the game. It comes from the 50 after the least interesting successful Dennis Norfleet kick return ever (run to the right until the kicker stops you), and Michigan comes out in an ace set. Miami has a 4-3 under on the field (sort of; their SAM is 190-pound Lo Wood) and will roll a safety down for guy #8.
Michigan's going to run inside zone and things are going to go pretty well all over the field with the exception of Mason Cole and AJ Williams trying to handle the backside DE.
This is your presnap setup:
There's a one-technique NT and a five-tech SDE. The SDE is splitting Cole and Williams down the middle, and the play is going to the top of the screen. It is very hard for backside blockers to do anything with a guy who is 1) lined up playside of him when 2) they get no help. This is about to happen to Williams.
I'm not entirely sure why this guy is free to fly down the line and blow this play up. The other DL are handled by Michigan's OL driving guys lined up a half-step to the playside of them. It seems like he figures that the OLB is going to be there to clean up anything that breaks behind him, so gap integrity is for suckers. (Michigan will get a bunch of waggles off this tendency, as Miami isn't using that OLB to contain hard upfield.)
On the snap Magnuson hops over a half-gap to get the nose; Cole goes to his zone a gap over without touching anyone and then starts helping on Magnuson's block. Williams is going for this DE:
Williams does not get the DE even a little bit, and with Miami DL set up to the outside on the frontside of the play Green is correctly going right up the gut, something that looks promising as Michigan gets movement on the DL.
Williams was put in a tough spot here; even so this feels substandard. Annoying the guy, pushing him so that he's on the correct side of the LOS, maybe cutting him: all of these things are better than escorting him to the RB.
A yard later it's clear that Michigan has cleaned out the DL; one linebacker shot a gap and is going to help tackle here but without the space constriction provided by the Williams block-type substance shooting that gap is a dangerous game to play that is 50/50 to put the tailback one on one with the safety for all the yards.
Green falls forward for two as Magnuson finishes pancaking the NT. Cole ended up not really doing much of anything on the play.
And the slow version:

Not Just A Gimmick™, we hope. [Adam Glanzman/Special to MGoBlog]
For a player with a meager 113 yards from scrimmage in two years, Dennis Norfleet is the topic of discussion around these parts a whole lot, and that topic is usually "can we please get this guy the ball more?" This seems like an odd request to endlessly put forth regarding a player with 12 career offensive touches and zero touchdowns, but there's Norfleet atop the depth chart at slot receiver, and beyond that there's good reason to think he'll be a much bigger part of the offense this season.
Norfleet came to Michigan as the in-state recruit too talented not to offer late, even though he didn't fit the coaching staff's idea of... anything, really. He certainly didn't fit the MANBALL running back mold, nor the desire to head in the direction of fielding a receiving corps in which being 6'2" makes one a slot receiver. It felt like he was offered as an afterthought, and his usage in the years since reflected that; Norfleet would occasionally come into the game at the slot, get a totally surprising jet sweep, and head back to the bench to await his next special teams opportunity.
The problem with this wasn't so much the plays Norfleet was asked to run—getting a player that shifty in space is a good idea, and jet sweeps should accomplish that—but the obviousness of what he was going to do, and the fact that these plays often didn't fit into the larger scheme of the offense. This blog has extensively covered the constraint theory of offense—in essence, that an offense has a core set of plays, then "constraint" plays that take advantage of defenses overplaying those core plays—and that Al Borges went for more of a grab-bag approach.
Norfleet's longest career carry works as a great example of both the constraint theory and how he was misused, oddly enough. He broke a 38-yard run in last season's opener against Central Michigan when Michigan ran an end-around to him off a counter trap run; the counter action—especially the pulling right guard—drew the CMU defense to their right, and by the time the ball was pitched U-M's blockers had a very easy time sealing their men off from the real direction of the play:
This worked because Central hadn't yet learned that Michigan didn't ever really run the counter trap and that Norfleet's presence on the field almost certainly indicated he'd get the ball; it also helped that they were a 6-6 MAC team. Norfleet's runs after the opener weren't remotely as successful due to a couple factors: Michigan couldn't establish a base running game, and when Norfleet was on the field it was incredibly obvious what he'd do.

By the end of this article you should be able to make an educated guess
as to what Braden is saying to A.J. Williams [Fuller]
You may have heard Michigan has a new offensive identity, by which of course we mean Michigan now has an offensive identity. We think. We're told. Evidence for this is Michigan hired a new OC who runs inside zone, and he has even Brady Hoke talking about it being our base thing. This thing is totally happening. I mean if they hadn't sworn up and down for three years that Power was going to be their thi...
Let's just not go into that and focus on inside zone and how to watch inside zone, and how to be correctly disappointed with the correct person when inside zone isn't run very well. Since this is a new thing, and the offensive line are all relatively new things themselves, and the recent history of Michigan football has given you no reason to believe otherwise, and there are some really good defensive linemen Michigan has to go against this year, let's concede right now that Michigan isn't going to be running inside zone very well this season, especially early. Let's pretend like the coaches are going to stick it out anyway and let it play out.
IZ Resources: As well as the above-linked articles, I drew from Chris Brown at Smart Football, and this article that quotes Chris Brown on a Philly Eagles website. And Space Coyote wrote an entire article on IZ and some plays that stem from it in this year's HTTV; I'm sure he'll pipe in as soon as I mess something up here.
|Every blocker is responsible for whatever defender appears in the "zone" he's responsible for blocking.|
A Temperate Zone
What's inside zone? Maybe it's best to start with what it's not: man. In MANBALL, most linemen have an assigned guy to block; a lead blocker (sometimes a puller) is the only dude who has to make a tough, mid-play decision, and the running back just has to follow that guy.
Inside zone is a base running play where all the blockers are reacting to the defense, not just a lead guy, and the running back has to choose from among various holes that could open up. It takes a different set of skills, mastery of a different set of blocks, and most of all: reps reps and more reps so that everybody can make split-second decisions and those decisions will be correct.
That's not to say all decisions are made after the snap. In fact most blocking assignments are determined by how the defense is lined up. In many cases it won't be all that discernible from man-blocking.
yellow is uncovered. click bigginates.
The read OL have to make is whether they're "covered" or not. Covered means there's a DL lined up across from you. If there isn't, you are "uncovered" and most likely you'll get to go hunting linebackers. But first you look next to you and see if there's a defender shaded to the playside of your buddy; he may need help with that lineman before you release downfield. If that defender is a beast your buddy may need all the help he can get. You deal with the first level defenders before you worry about stopping linebackers.
Almost always, more than one defender will arrive in a blocker's zone. So zone blocking means lots of shared blocking. Ultimately the blocking ends up being 2-on-2 instead of 1-on-1. For example in captioned illustration above-right, the center and right guard are together responsible for blocking the nose tackle and the middle linebacker.
Offensive linemen in high school seldom get the right footwork down. Zone-blocking footwork isn't the same as pile-driving some dude, for one; and two it's not something many high school coaches know how to teach; and three if you're a 6'6"/300 future Big Ten OL and your job is to block a 6'0"/180 future Big Ten economics major, your greatest motivation to pay attention to your feet is probably the preservation of your prom date's.
In this moment it matters greatly. You need to get off the snap, get playside of your defender, get downfield, and get your feet set beneath you, your hands inside, and your pads beneath his so you can ride him out of the play, stonewall him, or shove him downfield; you let him dictate his fate.
On inside zone, an uncovered guy's first step is always to the play-side, not directly toward the guy you're going to block (the OL taking this step is a good indicator it's a zone-blocked rather than man-blocked play). This is because the DL don't always come straight upfield; you don't want them running by you.
Your job is to block the guy trying to cross you. If someone lined up inside you and ran further inside you, he's not yours. Your head stays downfield until you lock on a target, and any object that attempts to cross your field of vision must be stopped.
That Rabbit's Dynamite
Interesting example of a 1) a cutback and 2) the U starting on the strongside of the formation then executing his backside block almost like a lead blocker
Mastering the combo blocks and footwork to respond to all the things defenses throw at you takes a bazillion reps. The upside: inside zone, like option offenses, is a multi-attack threat that can go where the defense doesn't. A called IZ play could end up going outside, or inside, or cut to the backside depending on how your opponent defends it. A well-run IZ offense doesn't let defensive fronts play aggressively; if they want to stop you they'll have to activate the safeties in the run game, opening up the pass. It's not wimpy; it's smashmouth football that—as you'll see—relies mostly on crushing blocks to break things big.
[After the jump I'll show some sample executions versus various defensive alignments so you can get a sense of how it attacks and what factors lead to its success.]
So we've got ourselves a new offensive coordinator. I guess there's no use hiding that I'm on the more ambivalent end of the spectrum of Michigan fans, but I'm a spread zealot, and I admit another gorram transition is just too painful a prospect right this moment. At the very least it was the kind of PR coup that resets the countdown clock on Hoke's tenure. These days you only get to play the "it was my offensive coordinator's fault" card once per Rose Bowl trip, but this was the right time to do so. I'm probably just a cynic who's been sold a bill of Mariucci over Mornhinwheg to believe in any apparent upgrade. Let's see if the readers can convince me otherwise.
Eye of the TIger tried. He found some quotes by an ex-Bama player on how Inside Zone is repped to insanity, which can be taken as evidence of philosophical thinking, or taken as the zone version of Hoke's "Power" philosophy which admittedly never materialized under Borges anyway.
|The thing about Barrett Jones is you don't have to make tough decisions about what your OL can and can't do.|
Tiger pointed out that Alabama's riches in offensive lineman size allowed them to depart from the typical suite of complementary plays and players that limits you to. It's supposed to be this:
Inside Zone has another advantage--flexibility:
The majority of the time in a zone blocking scheme the tailback will follow the design of the play, but occasionally the tailback will perform a cutback and change direction during the run. A cutback is when the tailback changes direction and runs away from where the linebackers are flowing (the tailback can only do this once and must not hesitate). This cutback made by the tailback is what makes zone blocking so dangerous because of how easily a cutback can lead to a big play. The cutback exaggerates the advantages of the zone-blocking scheme.
Watch this video highlighting Texas’ use of Inside Zone to see this point illustrated nicely, not only for cutbacks, but for alternate read options.
Major advantages: You can run an offense with less experienced OL and opens up a bigger growth curve for RBs, who become more effective the more comfortable they get at reading the holes and cutback lanes.
Major disadvantage: It's way harder to run play-action from a zone running look. Reason is nothing gets defenders thinking run like a good running MANBALL (or inverted veer) team pulling a guard. Second reason is the small, cut-rate scatbacks that zone lets you get away with don't typically make very good pass blockers. I probably don't have to tell this to 2013 Michigan fans.
At Alabama they overcame the disadvantage by having massive/quick OL who are naturally difficult obstacles to a pass rusher, and with 5-star running backs who can cut, block, slam, juke, and jet, all for three easy payments of $3,995.95, plus shipping and handler's fee (order now and we'll throw in a free safety). At Michigan, well, actually, we've got just those kinds of guys on campus now. Maybe?
Also there's this:

[After the jump: the board goes Borges for Nuss]
FORMATION NOTES: Northwestern stuck to a 4-3 virtually the entire game, with pretty predictable rules as to how they would line up.
When Michigan aligned its strength to the short side of the field and had twins, NW would slide the LBs and play an even front. They would slide the LBs to the twins and shift their line to the strength of the formation when M aligned with their strength to the field.
When Michigan presented Ace, they would play a 4-3 under.
The primary exception to this was the redzone, where Northwestern played their safeties as extra LBs.
Five yards off the LOS and coming on the snap is why those two Derrick Green carries from around the ten ended up losing yards. The first one was actually blocked quite well.
Note that the way NW aligned consistently invited the bubble fake run game, as their corners played off and the slot LB had to respect the bubble. With a safety over the top those two guys removed three players from the box and left Michigan with seven on seven blocking opportunities without having to use the threat of Gardner's legs. It will still work if teams play Michigan like this; if they don't Michigan will have to find something else.
SUBSTITUTION NOTES: QB, WR, and the OL were all as you would expect. Dileo seemed to return full strength in this one and this meant Jackson was removed. Paskorz got some early PT but it was Williams most of the way as inline blocky guy. The line remained Lewan/Bosch/Glasgow/Magnuson/Schofield save for some goal line plays on which Kalis game in at RG and weird stuff happened otherwise, like wing TE Taylor Lewan.
Running back was of course an overhaul, with Derrick Green getting the bulk of the work, De'Veon Smith becoming a 30% second, and Justice Hayes acting as a third down back sometimes. Joe Kerridge also got a few snaps as a running back in the shotgun on passes.
[After THE JUMP: wherein we seem relatively happy with nine points in regulation.]
Every time I post a play analysis these days there are a half-dozen people in the comments who mention that if player X did hard thing Y they are not prepared to do then the play would work. This has gotten to the point where I can explicitly prepare for such criticism and find them ignored, as in the most recent one, and find a diary on this site asserting that if player X did hard thing Y something would have worked.
This is extremely frustrating to me, because these are good-faith attempts to paint broader pictures of what I'm seeing down to down, game after game, year after year, as I try to figure out what Michigan football is doing. Various critics, most prominently Space Coyote, make a few small concessions and then go about explaining why play X was a good call and why it would have worked. They implicitly assert things like "Joe Kerridge in a ton of space should deviate from expecting Nebraska to use their slot LB as a force and ably block that guy when that LB believes the inverted veer is coming, has no need to respect the slot receiver because he is covered, and runs directly into Fitzgerald Toussaint."
I disagree with that. I have watched a lot of people play a lot of football and I think that's hard. I'm trying not to have a stance here; I am evaluating whether I think a thing is easy to do or hard and assigning a number to that feel. Coaches tend to think everything is an execution issue. Players should be able to do arbitrarily hard things. Some arrows on a diagram say this should work. Meanwhile I think there's a 10% chance for Kerridge to abort the plan and do anything with hell-for-leather blitzer and judge accordingly. Various guys dying on Borges Hill disagree.
I don't know what might be sufficient other than 175 yards against Nebraska to convince these guys that a poor offensive game plan can even exist, but here are various things that are normally too dull to post in a Picture Pages in which unblocked guys on blitzes obliterate Michigan runners for no or little gain.
These are representative of a larger slice of the game and a general feel that confirmed the Nebraska players' postgame assertions that they were expecting most of what Michigan threw at them. Tomorrow's Picture Pages will cover every play of the game, because this isn't going to work either.
Here is an iso. The slot LB is an eighth guy in the box and crashes down unblocked to tackle.
As this goes for three yards it qualifies as one of Michigan's best plays on the day on the ground. Three yards is not good on first and ten, and there was nothing Michigan could do about it.
Here is a zone play. Nebraska loads up and sends a blitz through a gap that Michigan doesn't pick up as Bosch ends up doubling with Lewan.
However, because of the blitz the only thing Bosch making a very good play to recognize and pick up the charging LB does is send Green to one of the two unblocked guys, either the backside guy ripping down the LOS without thought of checking the QB or a linebacker sitting two yards deep without anyone trying to get him, because Nebraska's blitz has prevented anyone from moving to the second level.
Here is a power play. Nebraska loads up with eight in the box and one deep safety and blitzes.
A Nebraska linebacker ends up shooting the gap behind the Bosch pull and meets Green in the backfield.
Michigan loses two yards and has third and eleven.
Oh for pants' sake.
The offensive line is not in fact overwhelmed here; they are not actually involved because Nebraska's blitz is perfect to destroy the inverted veer.
Items Of Interest
All of this is an execution issue, sure. For a given definition of execution, this is an execution issue. Michigan's hyper-raw OL should be able to block this. They should be able to deal with Nebraska switching gaps and blazing LBs to the point of attack. They should be able to block Nebraska's maniacal run-oriented loaded box. They would do this, if only they could execute.
Except the last one. And the first one. And probably the second and third.
Either you believe that players can be put in positions they can succeed or players are expected to succeed in the positions they are put in. I am in the former camp. The last few Borges defenders are in the latter camp. This entire season Space Coyote has been gamely explaining what should have happened on failed play after failed play without any thought to how difficult what should have happened is.
Players do not exist in a vacuum. Joe Kerridge is trying to block a guy in acres of space and that guy has the jump on him because he knows Funchess is covered, and he knows what Michigan's running. I look at that and I think "Jesus, I do not want to be Joe Kerridge there."
I am admittedly working from a hand-waving feel on this, but it's no worse a feel than whatever Space Coyote has gotten from doing whatever he does with whatever team at a totally different level of competition. I say Michigan puts their players in a spot to work miracles or die, and that this is on both the overall structure of the offense and the predictability of playcalls based on formations and down and distance. Space Coyote makes certain concessions to not seem totally insane and then goes back to hammering the fact that it's all execution.
Kerridge was put in a spot to fail, and did. I'm looking at the play and saying I believe there is a small chance that Kerridge can make a tough play in space; the guys in the comments think that because Kerridge could hypothetically have made a play none of this goes back to the folks in charge.
These plays. The above plays are no-chancers for the offense, because Michigan is running into the teeth of a defense stacked to stop the run and blitzing. In UFR lingo they acquired sizeable rock-paper-scissors minuses. In compensation Michigan got two screens which both got large RPS plus numbers, but the number of downs thrown away in this game running at a Nebraska defense that seemed to be in Michigan's head was alarming. When I add it up, I am guessing things will come out highly negative, and then people will cluck at me about that.
I won't deny that things are more likely to get put in the negative bin there when you have fewer options because you're not good, but in my opinion running plays you suck at into stacked boxes is a bad idea. So is the continued deployment of Toussaint as a pass blocker on plays that take forever to develop. That, too, is an execution issue, but it is nuts to expect him to block guys now, and the offense would be better served if he was used in a pattern or replaced by a fullback or something. Instead… he is not.
But yeah yeah, the expectation is for the position.
