you can't have one without the other without this one
You know the drill by now: always Denard's legs always. Michigan went away from using Denard's legs as a threat against Iowa and suffered through a day where their tailbacks averaged 3.6 yards an attempt. Against Illinois virtually every play saw Michigan threaten a Denard run, often with the additional threat of a triple option from a motioning slot receiver or fullback Stephen Hopkins
Additionally, Michigan brought back Rodriguez's old offset H-back formation. This allowed Kevin Koger to either flare backside and open up the designed cutback runs Toussaint had success with or attack the frontside of the play on QB draws and the like. This stretched Illinois out and gave Toussaint some extra creases.
Toussaint's 65-yarder on Michigan's second play demonstrates both of these changes. It's second and ten after the NT jumped he snap on the first play and Denard missed a keep read on a triple option. Michigan comes out in a formation that could be a shot from any of the last three years but for the WR tight to the line at the top of the screen, who isn't actually a WR but is TE Steve Watson. Illinois responds by shifting its linebackers to the field and half-dropping the free safety.
There are five second level defenders on this play: the three linebackers, the overhang corner, and the rolled-up free safety.
On the snap Koger starts to head backside. The slot LB charges on an exchange as the backside DE comes in unblocked:
By the mesh points defenders one and two are dead on a handoff.
CAUSE OF DEATH, DEFENDER 1: Scrape exchange designed to contain threat of a Denard keeper; Koger's backside block.
CAUSE OF DEATH, DEFENDER 2: Drop into zone designed to combat the threat of a mesh point oh noes play-action pass (that still does nothing to combat a bubble screen or quick out by Hemingway.
Denard sees the DE containing and hands off. Koger comes backside to prevent #1 from running down the line and making the play from behind. Defender three is blitzing up the middle…
…he manages to get through the small gap beween Huyge and Omameh but the two guys combine to slow him down long enough for Toussaint to hit the hole.
CAUSE OF DEATH, DEFENDER 3: Blitz picked up by Huyge and Molk.
The Illinois line creases between Schofield and Molk. With the Illinois line clearly slanting to the playside this is mostly thanks to Molk controlling the NT well enough to prevent him from getting upfield. This defense is clearly designed to get Fitz cutting to the backside of the play; Molk's block means he doesn't have to.
By the time Fitz is hitting the line, the gap is obvious.
When he's two yards past it Illinois is done.
CAUSE OF DEATH, DEFENDER 4: General uselessness of one guy in twenty yards of space against a blocker; need to maintain leverage.
CAUSE OF DEATH, DEFENDER 5: Derp. He's containing Denard Robinson, who doesn't have the ball and was never going to have the ball on this play, or he's anticipating a cutback that he doesn't wait to see develop.
Toussaint gets tackled by his shirt tail because that's what always happens to Fitzgerald Toussaint.
He manages to pick up another 15 yards after the initial contact, but someone needs to get Fitz a slippery jersey.

Denard's legs: all threaty and stuff. The zone read fake eliminates one linebacker, which helps the run game but isn't a miracle. When Michigan operates from under center they still eliminate a guy because all defenses leave backside ends for potential bootlegs.
Where operating from the shotgun helps Michigan is with defender #2, who has to back out into a short zone because of the threat of a quick seam over the top. The quick PA ability of the spread 'n' shred means any linebacker who sucks up and reacts is DOA.
This is enough to put Toussaint one on one with a safety. Since that safety derps it's one on none. That's a third player the threat posed by Denard in the gun eliminates. That's their starter and fourth-leading tackler, by the way. Don't know what it is about Illinois safeties and massive breakdowns on Michigan's first possession but I like it.
Molk's block: key. Illinois is slanting the line hard and trying to funnel the play back to their backside blitz. If Fitz has to cut behind Molk that blitz may or may not get home. Since he's got a crease to the side where the Illinois line slanted it has no chance.
This isn't entirely up to Molk. Zone blocking is frequently about taking the guy where he wants to go, then taking him past that point. You can see on the replay that the backside DT is slanting, then stops, then tries to extend as Fitz hits the hole. He waves an arm at him but can do no more.
If the NT pushes hard to the playside Molk is tasked with kicking him past the point he wants to end up at; with the MLB handled by two guys Fitz likely has a cut either way. But not getting blown up/shoved back/chucked provides the crease.
Flinging Koger backside: nostalgic. Michigan also did this with Hopkins when they aligned with two backs. This is likely because of a heavy dose of plays like this where Illinois takes a quick linebacker and shoots him down the line.
A few years ago Calvin Magee said he'd worry about the guy crashing from the end "when he makes the play" on stretches; Illinois's goal with this exchange is to make the guy left unblocked a quicker player with a running start. On inside zones blocking the backside guy is mandatory because all possible creases are in the danger zone.
The bubble: screamingly open here. The slot LB will blitz as the MLB drops into coverage, so… yeah:
On this play the threat of the seam still eliminates the linebacker that the bubble usually forces out of the box*. I am still in favor of at least throwing a few bubbles because they will pick up big chunks if the defense plays like this.
I'm in favor of them generally because they put pressure on the defense by restricting the ways they can align without either getting 8 yards in their face or playing games that end with Worst Waldo passes. I mean, by the snap there isn't a guy on the field with a prayer of defending a slot bubble here.
*[When it doesn't it's forcing a safety either to the line or into a dangerous game of jumping the bubble route and opening up wide open bombs.]
This week in spread zealotry we've got an example of something you can't do against the spread without getting a face full of Denard: crash. It's second and three early in the third quarter. Fitzgerald Toussaint has just taken an iso seven yards thanks to Molk and Hopkins making quick work of the NT and MLB.
Michigan will run an inside zone from an ace set. I'm pretty sure that Michigan screwed this up because I've never seen an inside zone play on which a guy who is not the end man on the line scrimmage is let go unless he's getting read. Here the backside DE is let go while Watson flares out to block a guy with a longer path to the ballcarrier.
Get used to both halves of this. Iowa is in a 4-3 under. The key guy is the DE at the top of the screen—the guy in a two point stance next to the standing SLB.
Michigan runs an inside zone. They double the NT and the SDE (at the bottom of the screen) as the linebackers flow to the LOS.
By the handoff point a couple things have happened. Both linebackers are at the LOS and engaged; the MLB is actually doubled by Lewan and Schofield. Sometimes a doubled LB means you've blocked a play so well that there's no one else to get. Not so much here.
I don't want to make too much of this because this is clearly a bust by the line (in all likelihood Lewan), but when I saw this I immediately wished Michigan was in the shotgun and Denard was reading the guy they let go. He'd have two choices: remain responsible on Denard and open that cutback up (he'd likely recover in time to tackle but not at the LOS) or do what he's doing now and put Denard one on one with the safety.
Similarly, with the linebackers one and two yards off the LOS, a pass like the one that started off their second hurry-up drive would be open. These things are all possible if you're reading the guy you've let go.
When you're not he just tackles you.
Toussaint does make the guy miss, but only by redirecting into a pile of bodies. He gets a yard. On the next play Michigan runs a QB power with Denard that Iowa is all over until two guys fall down after beating their blockers to the spot. Twenty two yards later they've got a first down. A field goal results.

This seems strictly less effective than the same thing run from the gun. I'm not sure what the advantage of operating from under center on this can be. You hear a lot about getting downhill quickly as an advantage of playing from under center, but pistol sets and even Michigan's old belly setup where the QB is a yard in front of the tailback get guys going downhill pretty damn fast without giving up the mesh read.
The other advantage suggested by commenters when I tried to answer some guy's question about the advantages of the I-Form over the spread was an ability to keep your eyes on the coverage downfield instead of catching a shotgun snap*. Here Robinson turns his back to the defense and has no idea what's going on behind him until he turns around.
So… yeah. Living in a world without post-snap reads is giving up something when your quarterback is mobile.
This is an example of the "ten man football" Borges was talking about. Even so, the play should still work for a few yards. The blocking's decidedly mediocre—in the last few frames you see a DT chucking Omameh, forcing the cutback—but the nice thing about the zone is it's hard for the defense to be right when you've got an effective cutback runner. Toussaint is that.
If the backside end actually gets blocked, Toussaint looks like he has the cutback for decent yardage. While that safety is probably going to come down and hold it to a modest gain, the first down is well within reach. Lewan busts and Michigan gets zilch. That was a theme on the day: one guy doing something wrong on these run plays and Michigan getting stuffed.
I wonder if spread stuff has a greater failure tolerance. You'd think it would because you are optioning off a potential defender and therefore get a double on someone. The alternative is forcing a safety into the box, which isn't bad.
*[Something that didn't seem particularly convincing since the shotgun is the preferred passing formation for long-yardage situations and hurry-up even in the NFL.]
A little more on what looks to me like one of the major issues with the run defense: the two MLBs not reading plays quickly enough. This was one of the videos featured in the UFR, FWIW.
Michigan State has first and ten at the beginning of the third quarter and will run an inside zone from an ace formation; Michigan is in their standard 4-3 under with Kovacs rolled down:
On the snap State starts to develop the run action and the linebackers start creeping forward:
A moment later the handoff point is almost reached and the two LBs are still three and four yards off the LOS.
Contrast this with the MSU defense on Michigan's first and five on their first drive:
Both are two yards closer to the LOS and rapidly approaching. This was a consistent theme: MSU linebackers, even when not blitzing, were screaming at the LOS.
At the handoff there is one blocker for two guys because Heininger was doubled on the backside. Martin is driving his single block into the backfield and Van Bergen is cutting off the outside. Kovacs is still hanging around for backside bounceouts.
The above is not a good setup for an offense.
But Demens does not get outside his block.. and Hawthorne starts moving up into a hypothetical gap that the RB is not headed to. Even if he wants to cut backside the Martin penetration means it will take absolutely forever. Still, he starts moving straight upfield instead of flowing to the hole:
By the time Baker manages to squeeze through the gap left by the DL, Hawthorne is hardly closer to him than when he was three yards behind the LOS and Demens is still two yards downfield, not funneling the play back to help.
Baker pops outside. Countess fills quickly, but can't make the tackle…
…and neither can Ryan.

The DL cannot do much more than this. They got a two-for-one on the double that leaves a free hitter. On the frontside they drive into the backfield such that the tailback has one realistic option. Short of throwing offensive linemen into the RB, they have done all they can.
The linebackers are uncertain of what they are doing. This has been a theme all year: me complaining about guys pulling in front of the LB's face only for that LB move directly upfield instead of scraping over to the POA. Sometimes poor DL play has washed them out, but often it's just derp.
Both linebackers screw it up here. Demens has to get into his blocker further upfield; failing that he needs to pop outside of him to funnel back to help. He does neither. Hawthorne can't see that his assigned gap is not an option because of the penetration and slows up for what turns out to be no reason. Either could have made this play themselves; it takes both of them screwing up to send it to the second level.
I'm sure they're more concerned about play action than Michigan State was because of the quarterbacks in question, but they get blocked way too often for my tastes. Hawthorne had already given way to Morgan for a series or two in the first half; IIRC this would be one of his last drives before Morgan re-entered for the remainder.
Ed Baker is hard to tackle and fast. I wish he was on the football team I liked instead of one I do not.
Countess does a great job here. I know he misses the tackle but a cornerback impacting a tailback just outside the hash four yards downfield is quality run support. If the linebackers hadn't compounded their Keystone Kops impression by banging into each other and falling over Baker is gang tackled after a moderate gain; as it is only Ryan is there to tackle and he is run through.
My eccentric Oregon financial advisor doppelganger. Smart Football points to a fellow who goes by FishDuck and is all about zone reads, feeding his dog, the violent-yet-genteel devouring of Mike Patrick, and more zone reads:
An interesting point picked up from Chip Kelly's presentations: Oregon has tipped inside/outside zone for six years without ill effect because declaring the play causes people to overreact to it, which opens up constraint plays. More than that, the zone often acts as its own constraint as over-aggressive players flow playside or bunch up inside, opening cutbacks and bounces.
He's also got a video on Oregon's deployment of power, which it uses as a counter to their usual inside zone stuff. We haven't seen this out of Borges yet, but I'm hoping. My desire to see Michigan pair an opposite-side-of-the-line speed option with the inside zone borders on lust. And by "borders on lust" I mean "invades Poland with sexy tanks."
When he was hired in January, Hoke's mission was explicitly to roll back the Rodriguez era, to restore whatever it was that made Michigan feel like Michigan again. To that end, even Wolverine fans seemed to find the sudden proliferation of countdown clocks, macho posturing and various Buckeye-related eccentricities laying it on a little thick. But six weeks in, the Wolverines are right on schedule in the national polls, the Big Ten standings and the weekly stat sheets. If they clear the midseason hurdle Rodriguez's teams never could at Michigan State, they can claim one more phase of the mission accomplished.
Kind of a big deal, this game.
Point: Tim. Reportorial ex-girlfriend Tim, who now goes by the bizarrely long moniker "Tim Sullivan" over at Rivals, was a committed skeptic about Rob Bolden since he was one of a trio of touted in-state quarterbacks in the 2009 recruiting class.
Despite the rankings, Tim said the guy didn't know how to play football. It seems like his scouting prowess has been borne out:
Game Over, Man. Game Over. This quarterback contest is done. Urban Meyer remarked toward the end of Penn State's first offensive drive that at Thursday practice, he did not see Bolden complete a single pass over five yards. This makes sense, as Bolden did not throw a single decent pass on the entire first drive. …
Rob looks completely shattered at this point, and it's time for the coaches, players, and fans to embrace the crazy train that is McGloin Moxie Mania.
It's McGloin o'clock in Bolden's Penn State career. Beaten out by a walk-on, does a transfer again beckon? /NYT headline writer imitation
Point: Hoke. Shudder at the awful puntasaur display in the Iowa-Penn State game:
…Iowa got to the PSU 33, faced 4th and 8... and punted. That Guthrie was able to pin PSU on their own 10-yard line (a solid accomplishment) is irrelevant. Punting from the other team's 33-yard line is A F---ING STUPID AND TERRIBLE IDEA. I don't even need statistics to back me up on that one (although they would). Even if Ferentz didn't want to try to convert on fourth down (4th and 8 isn't easy, obviously), why not give Mike Meyer a crack at a field goal? It was a beautiful day, the ball was lined up near the middle of the field, and Meyer has made 50+ yard field goals in the past (this year, in fact). But no. Ferentz gave a vote of "no confidence" to both Meyer and his offense on that play. Iowa probably deserved to lose the game for that decision alone.
Of course, JoePa was determined to out-conservative -- or out-dumb -- Ferentz; he punted three times from the Iowa side of the field, including late in the game on 4th and 2 from the Iowa 36. If he really didn't think his offense could rip off a two-yard gain against a gassed and reeling Iowa defense, I... I just have no words for the level of neanderthal football thinking on display in this game.
Of course, that coaching blunder on Ferentz's part might be narrowly eclipsed by the decision to eschew running a two-minute offense upon getting the ball at the Iowa 20 with two timeouts and 1:42 to go before halftime. God forbid we try to score there. It's not like we don't have a no huddle offense that's been effective this year or a kicker with decent range. Nope.
Even if trying the field goal with Gibbons is a mistake, it pales in comparison to that business. I cannot express how much I love the Mathlete's new Dumb Punt of the Week feature. The inaugural winner is Ohio State's Frank Solich, who punted on fourth and one from the Buffalo 36. Buffalo has the #91 rushing defense. After an 11 yard punt, Buffalo drove for a touchdown. Ohio State lost by a point. The game theory gods do not take kindly to being spited so grandiosely. (See also: Kirk Ferentz.)
I missed another Hoke game theory bit: he got the ball at the 22 with about two minutes left and did not pull the Ferentz. Robinson rushed for a loss of one on first down, then five straight passes got Michigan to the Northwestern 44 before Robinson's third awful interception set up a Northwestern field goal drive. While we've seen Hoke eschew half-ending drives a couple times this year, those were with a minute or less on the clock, not two.
Now… it didn't work out that time, but these things are never 100%. Did it make sense at the time to try to score with a couple minutes left against Northwestern's defense? Yeah.
Glarb glarb glarb. So when Michigan shuffled its fullback on third and one and got owned I had a conniption fit. This was the result of DeBord Doom re-emergence:
That's the corpse of Steve Watson you see getting annihilated at the LOS. Glarb.
BWS picture-pages this and points out that the shuffling fullback opened up the Gardner rollout TD on which he had either the run or pass; I'm not so sure showing the first play is worth the cost to get a yard when your redzone offense seems to be able to get a yard whenever it wants. I like diabolical machinations better when they're like the above Oregon stuff—plenty diabolical in their own right without the counter.
Mitchbreaks. Mitch McGary's impending Michigan decision now seems far less certain:
Recently, reports came out that Mitch was nearing or had made a decision. However, Tim refutes that notion “He hasn’t made a decision. I just talked to him tonight (Monday night) and we talked about it a little bit. He’s coming home Wednesday night and we’re going to sit down and talk about it. They get a four or five day break this weekend so he’s flying in to O’hare and my older son will pick him up. We’ll be able to sit down and sort things out.”
Likely rumor vector: AAU coach to national guy, national guy tizzy checks in with coach a few more times, everyone wants to back off. Confidence level: reduced, but still high.
Etc.: Denard Robinson is healthier this year because he is homeopathic or something. Mark Huyge has had a tough year. Holdin' the Rope doesn't like "smug, pompous buffoon" Mark Dantoinio. Jon Merrill suspension 50/50 to end his career. Sad face.
I like Fitzgerald Toussaint. Think the kid has a bright future if his various limbs stay functional. Enjoy his running style. Get emails from time to time declaring "I don't know what you see in this kid." Sit and ponder these emails. Shake fist. Decide to write post about it. Fitzgerald. Toussaint.
So here's a reason I like Fitzgerald Toussaint: I think his vision and his shake are plus pitches, to borrow from another sport. Here's an example. It's first and ten on the SDSU 16 late in the fourth quarter with Michigan driving to clinch the game. On the next play Vincent Smith will jackrabbit his way into the endzone, but to set that up Michigan's going to Toussaint.
If this looks familiar, it should. This was one of the staple formations of the Rodriguez years. Here's Tate running it in the 2009 ND game:
Rodriguez would often send the TE backside to block the otherwise unblocked EMLOS as a counter to scrape exchanges. TE kicks out the guy coming down the line; WLB flies out to contain Robinson on the zone read, and viola:
[one of many examples that have been DMCAed by Thought Equity Motion.]
Michigan did this on the previous play. It was the first time they'd run it all game and it worked like a charm, opening up a huge lane for Toussaint to hit. He did so for eleven yards. When Michigan goes back to the well a second time things will be different.
SDSU's 3-3-5 was less dynamic than advertised. Instead of blitzing like mad from everywhere to mimic different fronts, it was mostly content to line up as very small 3-4s and 4-3s and run twist stunts from them. On this play they actually line up in the stack, which was rare.
On the snap the TE pulls backside as the mesh approaches.
Robinson sees the OLB headed upfield at him and hands off:
The problem is Koger is kicking out the QB contain guy:
This is very similar to problems Michigan had running this play against Illinois last year. When the scraper is hugging the backs of the OL TEs often miss him and head to the obvious guy on the outside. Once your pulling TE whacks the contain guy you've given up the advantage gained by optioning him off and are back to—horror—regular old 3.9 YPC running. When this happened against the Illini, Michigan gained a yard.
Since Huyge has released downfield there is an unblocked EMLOS tasked with the tailback on a play that usually tries to go backside. (This is a zone, but it is a zone with an idea of where it's going to end up.) Omameh is actually doing a good job on his guy since the play design nominally expects the ball to go behind him. Unfortunately, that means there's nowhere to go further playside. There is no room.
So Toussaint makes some. In the above frame you can see he's evaluated his situation and is about to take a critical step. This is what he does with it:
That's weird. It's easier to see on the video, but Toussaint takes this jab step outside and then bursts back upfield.
This little jab step… what is it? He slows for a half-beat and sticks that leg out as if he's going to veer outside, then shifts direction and heads away from the scraper. Is it just instinct, or is it a deliberate attempt to set up his block? Does Toussaint even know? This happened in a blink. This may be one of those things even the person doing it can't explain.
The result is most apparent on the guy Omameh is blocking:
In frame one the NT has already committed his momentum to the other side of Omameh's block because of the jab step; in frame two he's kindly GTFOed, giving Toussaint a lane as Schofield and Molk donkey a linebacker who blitzed into them. Toussaint set this up with the step, which convinced the NT he needed to fight to the other side of Omameh without slowing him down enough for the unblocked scraper to catch him.
Result: Toussaint runs up his OL's backs for nine yards.
Watch it twice. Watch the step, and then focus on Omameh and the guy he's blocking. See that yank that suddenly repositions the defender? That's the NT moving himself to where he thinks he needs to be.
Will this be consistent from Toussaint? This is a play SDSU RPSed that Toussaint made into nine yards almost by himself with that jab step. Is that a fair representation of his vision and his ability to make split-second decisions that get him lanes other guys don't, or was it getting lucky? I don't know, but I do know that the last couple weeks I've had occasion to use "lovely" more than once to describe a Toussaint run. Early returns are "not lucky."
Back to the well. Yeah, this wrinkle was a Rodriguez staple. It worked like you draw it up the first time. This time it worked like you don't draw it up; Smith would come in and run it a third time for a touchdown, but he'd have to weave his way through defenders to do so. I'm not sure whether running it three times in a row was a good idea—it worked but clearly SDSU adjusted to it. Against better run defenses this might end up going splat. To be fair, the third one was a second and one from the seven.
Coaching points with coach Rod. In the Illinois game Michigan adjusted to the Illinois adjustment by the end of the game, coaching that pulling TE to ID the scraper hiding behind the line and blocking him into the endzone for a touchdown. It'll be interesting to see whether Michigan makes that adjustment if necessary in future games.
Further wrinkles. So there was this, which was brought out right at the end of the game, and the speed option you've heard and read so much about, a speed option that seemed to use outside zone "basketball on grass" blocking. That's an encouraging echo of the Rodriguez ground game, when most games of import saw new features being deployed.
This pair of plays is striking only in comparison to the defense. They're both inside zone runs Michigan gets about a yard on, but one's a third and goal from the one so that's all you can get from there. The first is in the second overtime; Michigan has just executed a throwback wheel of its own for a first down at the eleven. They come out in a three-wide.
Illinois does their usual bit with a linebacker over a slot receiver, but this time he's going to walk down and blitz:
Michigan's running an inside zone. This can go anywhere but on this play the hole opens up behind everything as Illinois is slanting away from their blitz. By the mesh point something odd is happening:
The backside defensive end is headed directly upfield. Most of the time the DE will either sit and contain, shuffle down the LOS, or roar down it. Here he's getting way upfield. Two reasons for this, I think: 1) he really really has to contain because of the corner blitz and must not let the QB outside of him, and 2) by doing this he guarantees a handoff.
Meanwhile, Webb's pulling to the backside of the play to get a block on whoever the cutback guy is for Illinois. Because of the switch this is not the DE but the slot LB. Webb does not realize this:
[Update: commenters point out this is actually Koger, which it is. Apologies to Webb.]
Oops. With Webb blocking the guy who the zone read is supposed to option off Michigan's left a free hitter on the backside. He tracks…
Michigan gets two yards and eventually has to resort to a Houdini escape when Terry Hawthorne jumps a third and eight slant. The deflection miraculously bounces to Hemingway.
The second play is Michigan's second to last play of the game. It's third and goal from the one. On first down an inside zone run was stuffed when Schilling got slanted under. On second down a QB lead draw was stuffed when Forcier went airborne unnecessarily. On third down Michigan comes out in a three-wide package. From the one.
Before the snap the corner walks down again:
Illinois runs the same curve, shooting the DE directly upfield after several plays where he was tearing downhill at the RB; he made the tackle on first and goal. Webb, however, is taking a much different angle:
Huyge and Omameh are blocking downfield but not that well. Spence chucks Omameh to the ground and shows up in the hole; Webb is still headed for the slot LB:
Shaw hits it directly upfield in this useless screenshot and does get the ball over the plane, but here's Tate celebrating:
So… that's an adjustment to an Illinois adjustment. After getting fooled by this the one(!) time it came out earlier, Michigan goes to the sideline for mere moments—the offense has to come right back out. In these moments someone grabs Webb and says "if the DE goes straight upfield your assignment is the linebacker crashing in from the slot." Then Michigan seems to invite that very play by coming out in a three-wide formation on third and goal from the one. They want that DE to erase himself and for a LB to get singled up on the 260 pound Webb. His block provides the extra momentum that barely gets Shaw over the plane.
The reason I'm so down on the defense and high on the offense is that these things seem to happen on one side of the ball but not another. It should be clear that no one's on the keeper when Scheelhaase takes it for big yardage, but then he does it again on the exact same play. It should be clear that something's not right in the way you're defending the option but nothing really changes. Etc. Michigan's offense adapts in ways the defense doesn't, and I don't think it's youth when the players who can't contain a keeper are Roh and Mouton.
Chitownblue asked about an RPS plus on the final play of the game, but that's an example of what I'm talking about. Illinois runs the same play they got their earlier conversion on and Michigan runs the same defense. You've got a rub route against man coverage and a seven-man protection you're blitzing into. If Illinois had gotten to pick Michigan's defense on that final play, they would have picked a man-zero all out blitz. They got it, but Jonas Mouton saved the day by making a great play. If he gets cut or just blocked Scheelhaase rolls away from Roh and has a receiver wide open for a score.
It is in these ways that Michigan's defense is different from its offense.
Bonus: you know that corner who jumped the slant in the second OT and should have had Michigan in fourth and long but for some Notre Dame-level BS? Michigan ran a circle route (a fake slant to an out) on the two point conversion and got Hemingway wide open.
