"It's a lot easier being a drug dealer than an AAU coach" - this guy. Tell me something I don't know. I mean, don't think but have never tried either.
The 4-3 is back, like it never sort of left and then really really left against Purdue and then came back and then altered into a slightly different version of itself and then mutated into a bizarre thing that was like the thing against Purdue but wasn't really because the person doing the mutating spent all his time watching his "Best of Just For Men Commercials" DVD. It will not suddenly be replaced by things that start with the number 3 and end with razorblades and pain. In the long term, this is delightful.
In the short term… eh… there might be some issues. This series is an attempt to fit Michigan's noses, ends, spurs, bandits, spinners, deathbackers, doombackers, dipbackers and frosting-covered gnomes into their new homes.
We start with the defensive line.
What we were forced to watch last year
Michigan stemmed into four man fronts occasionally but spent most of its time with a three man front featuring a traditional nose tackle who lined up directly over the center and two defensive ends. It was unclear to me if these defensive ends were intended to slant one way or the other at the snap—an aggressive "one gap" system—or if they were reading and reacting—a "two gap" system—because of the massive confusion surrounding them. It was hard to tell if Greg Banks was trying to cover two gaps unsuccessfully or just getting single blocked all the time.
They did typically line up slightly outside (lingo: "shaded outside") the tackles, indicating that it was probably the former:
You'd have to be the sort of idiot that would have Craig Roh play linebacker to play Craig Roh as a two-gap DE at 235 pounds, but… yeah.
At other times Michigan would switch to a four-man front in which their linebackers did things that made no goddamn sense at all, like on this soon-to-be 61-yard-touchdown…
…but that's another show. I bring it up to point out that in this situation you see Greg Banks as the weakside(!) defensive end, Craig Roh as the strongside guy, and Ryan Van Bergen folded inside to be the three-tech defensive tackle. This is a shifted line rather than an 'even' line, but more about that later.
What we were forced to watch the year before
Michigan ran mostly four-man lines and while they varied they usually put Brandon Graham on the weakside-ish of the formation. Here Illinois presents a balanced line with two TEs but you can see Martin lined up over the nose tackle and Graham to the bottom of the screen with a big gap between the two. Banks and Roh are to the top of the screen:
The linebacker walks down to the LOS in an effort to prevent Graham and Martin from getting double-teamed. When there is no TE on the weakside teams had a choice between singling Graham or Martin, which is why Graham got to eat the universe so often.
Sometimes they would line up differently. Here's another play on which Graham is on the weakside, well outside of the tackle as Martin lines up directly over the guard:
This is actually an "even" look where Michigan's not shifted. The DTs are over the guards, the ends line up outside the shoulder of the tackles.
They did occasionally stem into 3-3-5-ish looks, but note here that the defensive "ends" are lined up inside the tackles—this defense is designed to push runs to the outside.
Michigan ran this front most of the day against Ohio State and had success against their traditional I-form game, but struggled when the Buckeyes went to unbalanced spread sets. USC ran this quite a bit in the last few years of the Carroll regime; they called it "double eagle".
What can't possibly be quite as bad next year
My assumption is the defense is going to look a lot like the 2009 one did. That was a 4-3 under. I was going to go dig up old Michigan rosters featuring the "rush linebacker" to demonstrate that Michigan's old school defense also tended to have a guy hanging out on the edge made of menace and sacks while the other guy enjoyed fighting off tight ends but then I remembered Hoke obviated the need for circumstantial evidence:
“We’re going to be a four-three defense, either an over or under front.”
Those sound like two totally different things but they're not. This from above is an "over" front:
This is an "under" front:
And you're probably like "that's the same damn thing except Craig Roh is standing up." You're right. The difference in the pictures is the offense. In the MSU still there are more DL to the side with the TE and FB; in the Western still there are more DL away from the side of the formation with more dudes. Both have a one-technique DT and a three-technique DT. Both leave a big gap between the one-tech DT and the DT to his side. They're just mirror images of each other. A couple of helpful graphs from Shakin' The Southland to clarify. Michigan's overshifted line in the State image:
And the undershifted line against WMU:
The only player that ends up aligning differently is the strongside DE; it's really just flipping the tackles over.
That's still a useful distinction Hoke made for us, though, because a team that is under/over is going to have different requirements than a team that aligns even like Michigan did on that Iowa play above. We get to keep our terminology from two years ago when we talked about the three-tech DT and the one-tech DT.
Every team is "multiple" these days and will run under/over/even fronts as changeups. Also, the generally accepted theory is that under is better against pro-style teams that will bang your head and over is better against spread teams that will take your strongside linebacker into the slot. So when Hoke says "under/over" he probably means Michigan is going to run both depending on situation, not that they'll pick one when they figure out their personnel a bit better.
What you need at each spot
From right to left in the second graph above:
- The weakside defensive end is going to get a one-on-one matchup with the tackle most of the time and needs to turn that opportunity into plays. Think Shawn Crable, Pierre Woods, etc.
- The three-tech DT also usually gets a one-on-one matchup with the guard. He should be a penetrator that gets into the backfield with regularity. NFL DTs you've heard of (Warren Sapp is the canonical one) who aren't barely mobile piles of goo are probably three-techs.
- The one-tech DT is going to experience a ton of double teams as the offense attempts to attack the "bubble" in the front the defense leaves but not putting someone over the other guard. You know all those successful zone running plays the site has explained over the years that start with a guard blocking some DT and end with that guard plugging a linebacker as someone else slides over to finish the job on the NT? That's what you don't want your nose tackle giving up.
- The strongside DE should be Brandon Graham. Failing that, he should be a big, strong guy who's good against the run and can add some pass rush here and there.
A post from Battle Red Blog provides more detail on what your 4-3 under requires—at least on an NFL level—if you're interested.
Who goes where
Craig Roh is the weakside defensive end and will be backed up by Herron/Paskorz/Beyer/Heitzman. Attempts to move Roh elsewhere will be thwarted by a plucky band of kids and their dog ripping the Mattison mask off of a dastardly Greg Robinson.
There are two scenarios for the rest of the line. In the happy fairy dance scenario, Mattison, Hoke, and Beyonce are so much better than Bruce Tall and Greg Robinson that they transform the platoon of Will Campbell, Quinton Washington, and Richard Ash into a functional one-tech DT. Here's what happens if they don't and they move Martin:
Yeeargh. I'll believe Will Campbell can play D when I see it but Ash and Washington got some praise last year so you've got three bullets. It's possible this happens, if not probable.
If you can assemble a frankentackle in the middle then you can slide Mike Martin out to the three-tech spot he doesn't know he's been coveting for years. Imagine senior Martin getting single blocked on most plays. Tingling is normal when contemplating this scenario.
As a bonus, successfully moving Martin to the three tech allows you to leave Ryan Van Bergen at DE, where he is the kind of solid run defender you need on the strongside. He'll chip in a half-dozen sacks and be the B+ version of a strongside defensive end and that will be fine.
The realistic-thing-that-will-be-called-pessimistic-in-the-comments scenario is that Campbell/Washington/Ash produce a guy or two worth platooning but actually running those guys out as starters is asking to be smashed. This strands Mike Martin at the one-tech and essentially forces them to move Van Bergen back to the three-tech spot he occupied in 2009. Redshirt freshman Terrance Talbott is the only other three-tech on the roster until fall. Neither of these things are necessarily bad. RVB graded out decently in UFRs a couple years ago and picked up six sacks; Martin is good enough to play either spot.
What is bad is what that does to the strongside defensive end spot, where Jibreel Black would be an all-but-certain starter as a true sophomore. Black had some promising moments last year… as a pass rusher. He had many more in which his terrible run defense hurt Michigan, and while he'll get better it seems doubtful he'll get better fast enough to be an asset. The only other option at SDE is redshirt freshman Ken Wilkins.
It is possible that in this scenario they put Roh on the strongside since he'll be a junior and he's been less prone to crippling mistakes against the run. His main problem has been a lack of size that the offseason should come close to erasing. That would take a guy who's presumably going to be Michigan's best pass rusher and put him in a position to get doubled lots, though.
Awkwardness Rating On A One To Rodriguez-Interviews-Hoke Scale
Depends on scenario but this shouldn't be too bad. In the happy fairy scenario Michigan's personnel fits a shifted line like a glove. You've got three battleship type NTs, two guys on the weakside who will wreak havoc, a solid guy at SDE, and a scattering of decent backups.
Even in the regular non-fairy scenario you've got good personnel at three spots. SDE would probably be an issue. Either way it's way better than trying to use Craig Roh as a LB or three-man-line DE.
