i find this extremely interesting
[Sorry about the delay. Internet issues this morning.]
To continue a theme on Michigan's suddenly mediocre run game: dude, it was all Purdue's cover zero approach. Here's a play that's beautifully blocked all around and still ends up with meh results. It's Michigan's final drive of the first half; the Wolverines have the ball first and ten on their own 43.
Standard three wide from Michigan; Purdue moves their nickelback over the slot receiver and has their safeties in that no-mans-land between deep and shallow:
By the snap they're still in that shallow range; the deeper guy is only seven yards off the LOS—that's where WVU's stack keeps its middle linebacker. Michigan's going to run a stretch:
As usual the key block is the one in the center of the field, where Schilling and Molk are working to seal the playside DT. you can see above that the playside DE is not slanting inside this time and will get kicked out. Michigan is doing something weird, though: they are blocking the backside end. They've done this a lot this year but in almost all cases they've done it on inside zone plays where a cutback is one of the main ways to gain yards. On a stretch this guy is usually set free to fruitlessly chase.
At the mesh point Robinson gets contain from the safety no jk lol linebacker and hands off. Molk has already gotten across the playside DT, who is dead:
That is a dead DT. With Lewan getting a kickout Smith will have a hole to cut into. Schilling releases downfield and gets a good block on the playside LB; Koger heads outside and pulls the other safety no jk lol lb with him. Hurray yards?
Yes, but issue in the middle of the field wearing #45:
This linebacker is the guy Huyge would have released into if he wasn't blocking Kerrigan. He's totally unblocked and can run down the line as Smith zooms past dead DT and Omameh drives the backside guy yards downfield; Schilling and Koger have picked up eliminating blocks on the other LBs.
Through the hole, Smith is one on one with the LB…
The end result is a play where all six Michigan offensive linemen get blocks between good and great… and Michigan gets six yards.
Object lesson type objects:
- Generic stretch stuff. This is another example of how the stretch usually works when it works: Molk seals that DT, Lewan kicks the DE, Schilling releases into a linebacker, a lead blocker takes another one outside, and running back hits a big gap.
- Cover zero problem reinforcement. In this particular instance blocking that backside end is a bad idea, but with eight guys in the box Michigan knows they'll leave contain to a safety and send Kerrigan tearing down the line. If Smith has to cut behind Molk he will be swallowed at the LOS. There's a nonzero chance Kerrigan manages to grab Smith from behind even if the blocking plays out like this. Michigan has a choice between leaving the MLB free or leaving a guy they know will crash down the LOS free. In this particular instance getting a block on the MLB, even a crappy-push-by-the-RB-forcing-a-cutback block, is a touchdown unless Smith gets run down from behind.
The fundamental math is still the same: there is going to be an unblocked guy in the box and Purdue can slant and shift its defense in an effort to get the ballcarrier to an unblocked guy. On the previous example Purdue did this effectively; here they hang on by the skin of their teeth but do get it done.
- Weather allows cover zero. BWS did a post on Michigan's only successful gotcha play, the fourth quarter completion to Kevin Koger that jump-started Michigan's final touchdown drive and was so wide open Denard could throw a wobbly underthrown duck and still have it easily complete. The pass on that play and about a dozen other hilariously misthrown balls by all four quarterbacks goes a long way towards justifying Michigan's resignation to pounding its head into the wall repeatedly. I'm sure Michigan won't do this again—not that they'll have an opportunity against Wisconsin and Ohio State, two teams that won't run cover zero much if at all.
UFRing the Purdue game was a blast from the past, and in a frustrating way. After the first drive Purdue spent much of the day with eight guys in the box, and Michigan ran at them anyway. Since Michigan's always based out of a three-wide formation this is the equivalent of having nine guys against a tradition I-form; Purdue spent the day showing really soft man zero that may have morphed into cover three after the snap but still should have provided Michigan ample opportunity to exploit the big chunks of space Purdue was leaving open.
Look at Roundtree here:
That was his whole day: sitting by himself and never getting a bubble. There were a lot of reasons for this—primarily the weather and Michigan's reluctance to do anything risky against a Purdue offense that's much worse than Michigan's defense—that were in retrospect correct. At the time it was very frustrating.
Anyway, this Picture Pages is about what this eighth guy in the box allowed Purdue to do. Going into the UFR I was hoping I'd see something that would explain why the offensive line seemed to get whipped so badly, and I think this is it. So that's the setup above. It's Michigan's third drive of the second half. They start on the twenty, it's first and ten, and Purdue has eight in the box. Michigan runs a basic stretch at them.
A moment after the snap you can see that the Purdue linemen are slanting away from the stretch instead of flowing with it. This is not something you see often:
At the mesh point Robinson sees the slot guy containing and Kerrigan moving upfield past Huyge, who's releasing, so he hands off.
A moment after the handoff we see that Molk has completely sealed the playside DT. Normally on a stretch play this means the opponent is dead meat. That's because the playside DE has to maintain contain and sets up outside the OT, which means running a good distance outside, which means there's a huge lane for the tailback and whichever guard is playside gets a free release at one linebacker in a lot of space.
Here the DE has not maintained contain. He's slanted inside Lewan and threatens to get upfield for a TFL. Also the MLB is driving hard to the outside. Schilling either aborts his release to rub the DE or just gets caught up on the Lewan block in an effort to get out on the charging LB:
A moment later we see that Molk has erased both DTs with the seal but the playside DE is sitting in that hole. Lewan knows he's lost the battle and starts shoving him past the tailback. Smith has to go outside, where he's got a lead blocker in Hopkins against two Purdue linebackers. Schilling has no chance on the MLB since he shot for this exact hole at the snap:
A moment later Hopkins kicks one guy, Lewan shoves the DE, and Schilling is following the other linebacker into the hole. Smith's cutting up because he doesn't have much of a choice.
Linebacker is now the blur between Schilling and Smith. Schilling's managed to get him to run past the play a bit and he's got to make a diving ankle tackle…
…but he does:
Michigan receives zero yards.
Object lesson type objects:
- Purdue can only do this because they have eight guys in the box against six blockers. One goes with Denard, so that's seven on six. Normally you see playside DEs set up outside on the stretch because if they don't that lead blocker to the outside threatens to pound a single linebacker and send the tailback into the secondary. Here Purdue outnumbers Michigan, which allows them to slant that DE inside and still get two guys on the perimeter when Lewan pushes the DE past the back. Purdue consistently answered the "one safety or zero" question with zero, and these were the results. Here they get the play to go exactly where they want to and kill it.
- I don't think anyone blocking did anything wrong. The only block in question is the one on the playside DE where the guy gets under Lewan because he's slanting inside. If that DE gets past Lewan into the backfield that's a major issue but a main principle of zone blocking is you take the guy where he wants to go faster than he wants to go. Guy wanted to go inside, Lewan shoves him inside and opens up a crease at the LOS. Extra linebacker makes the play. The only thing I think Michigan could have done here is a weird anti-scoop where Schilling shoves the DE outside of Lewan instead of shoving the DT inside of Molk. I don't know if anyone's ever tried that so it's hard to blame the players.
- This is actually close to breaking for some yardage maybe? Despite all this Schilling's good-faith effort to do something with that filling linebacker and Lewan's ability to create a decent hole sees Smith almost cut past the charging LB, whereupon he'd get somewhere between five and many yards. He can't.
That's not a serious knock on Smith on his most effective day as a Wolverine. A back with the ability to make the cut he does on this sloppy field and the speed/power to run through that ankle tackle attempt would be a special guy indeed; hopefully Demetrius Hart can be that guy.
So, yes, I think I did find an explanation in what Purdue was doing that partially exonerated the offensive line. Michigan saw this front all day and kept running into it, which resulted in a crappy day on the ground. In this case the "crappy day on the ground" is 4.3 YPC excluding sacks, which is basically what good DeBord teams averaged on the ground. Since DeBord absolutely loved to run "away" from the extra guy and out-execute in the face of herculean odds, this makes sense.
Michigan's offense is going to net a huge RPS minus in UFR because of this rock, rock, rock playcalling, but don't take that too seriously. I get why they did it when Denard threw two horrible interceptions and a lot of his simple hitch routes to the sidelines were fluttering ducks. The conditions affected his throwing significantly, and allowed Purdue to spend 80% of the game running cover zero. When they stopped this on Michigan's late third-quarter drive from their own four, Michigan went right down the field until a clipping penalty on Lewan put them in second and forever.
More tomorrow when the offense UFR drops.
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.
Earlier in the year Chris Brown of Smart Football offered up some clarification of a route package Michigan's running, and now I'm spotting it in key situations so I might as well Picture Page it. This will please people who complain about the relentlessly negative PPs in past weeks that are all about explaining why Michigan gave up a touchdown.
It's third and four from the 29 on Michigan's second drive of the day. Michigan comes out in a standard formation:
Smith, Hemingway, and tight end Kevin Koger are going to run a snag concept. This consists of three parts:
- The #1 (outside) receiver runs a slant and then sits down about five yards downfield.
- The #2 receiver, in this case the TE, runs a corner route.
- The tailback runs a flare.
This is what it looks like on a diagram. It's on the right:
Chris Brown on the point of this package:
The snag is a variant of the smash, where one point is to get a high-low with the corner route and the flat route (except now the flat is controlled by the runningback), with the added dimension of an outside receiver running the “snag” route — a one-step slant where he settles inside at 5-6 yards. This gives you a “triangle” stretch, where you have both a high/low read (corner to RB in the flat) and a horizontal read from inside to outside (snag route to the RB in the flat).
In previous games when Michigan's run this the opponent was in three deep and the read was simply reading the playside linebacker: throw it where he's not. Here Illinois runs what looks like a combo coverage. Just after the snap:
Illinois has a hard corner to the bottom of the screen and a soft one to the top. Robinson's reading the snag package all the way. Here he's starting at the playside LB, who's figuring out what to do with Koger.
It turns out he goes with Koger:
The hard corner is taking away the flare and this linebacker is turning his hips, so the snag route itself (Hemingway's) will come open. Denard should probably be throwing the ball now.
He should definitely be throwing the ball now.
THROW THE BALL AAAIAIGH
Hemingway's about a half yard short of the first down and is fortunate that Martez Wilson read the route package about as fast as Denard did. He's still two steps away from Hemingway, allowing Hemingway to take that orbit step wide receivers to do evade overpursuing tacklers…
…which gets him past the sticks for a first down.
Maybe Michigan's passing game isn't as unsophisticated as the spread n shred used to be? This is a favored package around the NCAA right now, which is why Smart Football could bring it to my attention—he'd seen it in the Rose Bowl. Meanwhile, despite having a quarterback who's going to break the all-time rushing record for his position and possibly Tim Biakabutuka's Michigan rushing record, this is not the West Virginia offense. Disclaimers about Tate cameos and catchup ball apply, but Michigan's running 61% of the time this year. That's not far off from Carr's last three years, which were 56% rush (2007), 61% (2006), and 55% (2005) and it's a far cry from Rodriguez's Pat White offenses that ran 75% of the time.
Despite missing a game and a half, Denard already has more attempts than White did as a sophomore and needs just 22 attempts per game to match White's 274 attempts as a senior (which wasn't even an RR offense anymore). Michigan's 14th in passer efficiency, which says a lot more when you're throwing it around at a semi-normal rate.
- But maybe so, or maybe not. Previously in this series we've broken down the curl/flat combo (twice) and frequently mentioned the snag. Here Illinois runs a combo coverage that blankets the curl/flat to the top of the screen and probably should do the same to the snag but for Wilson's tardiness. They're prepared for this play. On the other hand, they were completely unprepared for the all-hitch routes that Roundtree kept dropping, and Michigan got their bomb on. So maybe nevermind.
- The game is still slowing down for Denard. This is the euphemistic way to say "he's not reading defenses fast enough yet." (For a given definition of "enough," anyway. He's 11th in passer efficiency.) He's late here and I think he was late a couple other times. It's hard to tell whether certain balls are inaccurate or thrown in the right zone window, but thrown too late. I think the fourth and nine Roundtree touchdown may be an example of this. He couldn't hit Roundtree in the numbers because of the safety coming over and forced a moderately difficult catch out of him.
- Great protection. This happened all day. Robinson sat back there like John Navarre, most prominently on the second(!) 75-yard completion to Roundtree where Michigan slid the line and he re-enacted his throw to Roundtree from the spring game except without the guy coming into his face.
- Maybe this is why he never scrambles? He seems uncertain about his reads still so he sits in the pocket wondering if he's missing something when he should just run, Forrest, run. For a guy with his ability on the ground he's got a weird antipathy for taking off. I've got him for four scrambles on the year.
Note: no UFR today, as the torrent got down late Monday and I couldn't do the first half then. Hopefully both halves tomorrow.
You'll have to forgive the picture quality on this one—both of these are low-quality torrents. Just like Michigan's defense. AMIRITE!
So in the game column this week I complained about the alignment of the middle linebacker in this bastardized version of the 3-3-5. Michigan has him maybe a yard behind the nose tackle, like so:
This creates a major vulnerability against misdirection, as we'll see. This play is a first and ten on Penn State's first drive. They've driven it into the Michigan half of the field because of depressing things, and more depressing things will happen. This isn't one of them. Michigan shows a two-deep with six in the box, but moves Kovacs down late to add a seventh guy, which gives Michigan the formation above versus Penn State's ace 3-wide.
At the snap the offset fullback heads inside the tackle to his side. You can see the handoff is going to be made to the right side of McGloin. Linebackers start scraping as each and every DE attempts to take on two blockers:
Here's the handoff point. The fullback is hitting the backside B gap, which makes me think this is a called counter play. Where's Demens?
Demens has taken a step towards the line of scrimmage and has hit a guard. Now… he hit the backside guard, the one that PSU is cutting towards. He read the play, but he's a linebacker two yards from the LOS meeting a guard with a free release who's much bigger than him. Momentum means that the best he can do is bounce off it and attempt to flow down the line. (This is much more apparent in the video below.)
The play cuts back as designed. Roh has attacked a frontside gap. Martin and Demens are caught up in the wash on the interior, and Mouton, who was scraping along well back of everyone else, is going to eat the fullback four yards downfield:
The saving grace here is Kovacs, who sifts through the blockers and makes a mediocre ankle tackle that the RB (Royster, I think) steps through:
Demens and others finish it off but after four yards:
Michigan got away with this by putting an extra player in the box late. When Penn State was not caught in a bad playcall, counters like this gashed Michigan all night.
Here's the video:
I don't have an exact replica of this from Rodriguez's WVU days but here's an inside zone Rutgers ran in their 2007 game. Rutgers was no joke on the ground in '07. Ray Rice was around and the Scarlet Knights finished 26th nationally.
The first thing that's obvious is that the MLB is six yards off the line of scrimmage, not two. Also despite playing against a bigger set—Rutgers has a tight end on the field instead of a third wide receiver—West Virginia maintains two deep safeties:
At the snap WVU has shifted to an aggressive look with the OLBs and the spur at the LOS; the MLB has moved up a yard:
At the snap six players attack the line, giving all but one WVU DL a one-on-one matchup:
This is a similar setup, really: inside zone. Main difference is that there is an inline TE instead of a fullback on the backside, but they block the backside end above. The playside end is about to beat a Rutgers tackle to the inside. Note the MLB two yards away from the LOS now—where Demens started the play—after the handoff. He's scraping to the hole. A Rice cutback would be somewhat problematic for him but he's not likely to get a lineman in his face:
MLB has now engaged an OL at the LOS. Rutgers tackle is totally beaten and forces Rice to start cutting:
There are four WVU guys in the area:
And Rice goes down shortly after he crosses the LOS:
On the day Rutgers would get 183 rushing yards, but Mike Teel completed under 50% of his passes and threw two interceptions on a 128 yard passing day because WVU left the safeties back the whole time. West Virginia won 31-3. Their rushing defense was 18th nationally.
- It seemed like Michigan was using Jonas Mouton like WVU used their MLB in the 3-3-5. Except Mouton was four yards off the LOS, not six, and not aligned in the middle of the field. So if he's going to get to anything on the frontside he has to run hard, which means he is susceptible to cutbacks.
- I don't think Demens ever had a prayer of dealing with a cutback or counter because of his alignment. One step to the playside and he's a yard away from the LOS about to get swallowed by a guard.
- Michigan plays Demens at the same depth in their other line alignments. 3-4:
Paired with the disconnect in WVU's 3-3-5 this signals shoehorning to me. Demens should be at a certain depth in more conventional sets and putting him six yards back would confuse him in pass drops, run fills, etc, but in the 3-3-5 he takes one step and there's a lineman releasing free into him. In these sets he's got a chance to scrape without dealing with an unblocked OL all the time. So…
- Michigan's deployment of the 3-3-5 isn't really a 3-3-5. I don't know what it is, but that whole attacking from everywhere, making different fronts, blitzing, getting guys through the line unblocked thing is something you can see on a fairly typical WVU play above. There are six guys on the LOS threatening and a dedicated cleanup guy behind them with the space and time to get anywhere along the line. Michigan is a passive three man line with guys you can easily single block (but get to double if you want) and linebackers who are living a nightmare. It's incoherent, and Michigan going back to it after having a fairly solid day against Iowa basing almost exclusively from traditional fronts is a miniature version of what happened against Purdue in 2008. Michigan's 3-3-5 is a 3-4 with linebackers in places that don't make sense.
- Michigan only escapes the above play by outnumbering the offense. No one on the defense beat their counterpart. Everyone was blocked out of the play, which means you can't win unless you've got an extra guy, which means you can't play two deep without getting smashed.
- I have no idea what Greg Robinson is trying to accomplish. This puts me in the same situation as Greg Robinson.
Promised last week but Wife Day occupied the designated space.
This week's great linebacker debate is about how I'm sitting in a tree with Kenny Demens, finding reasons to posbang him that would not be reasons to posbang Ezeh or Mouton. That's not really how UFR works on defense. A three-yard run is a usually a +1 for the D, a zero-yarder +2, and a TFL +3—though it's context dependent—and I try to assign credit and blame to get to those numbers. There is wobble when the other team makes an error or there's a rock paper scissors play. If I was going to give Demens positive he didn't deserve they'd be coming off his teammates in the front seven and the only guys to suffer relative to expectations were Rotating Ineffective Nose Tackle and the Banks/Black combo.
Mouton also come in for a big minus and clucking, but I thought that was easily justified by the clips provided. If it's not here's another one. It's late in the third quarter and Iowa has third and three from the Michigan eleven. They come out in an unbalanced formation with a covered TE; Michigan responds with a 4-4:
Iowa will run off the right tackle. At the snap Kovacs blitzes. Banks, the DE to the bottom of the screen, takes on a double team from Iowa's LG and RG; Renaldo Sagesse is getting single blocked by the center:
A moment later Banks and Patterson have both gotten in bad situations. Sagesse is a yard downfield and sealed to the inside. Banks has managed to stick at the LOS but he's about to be effectively comboed and sealed to the inside:
Kovacs gets picked off by the fullback. Roh's gotten a cut on the backside but Gordon is flowing behind him; RVB has gotten down the line to cut off a hole; Sagesse is getting buried by a double downfield. Mouton has set up on the Iowa RT as Banks just kind of sits there at the LOS:
Here's an endzone angle of the last moment:
That's a lot of grass to Mouton's right there. I wonder what he's going to do about that:
Dios ffuuuu, man. This will be clearer on the video but this was not some crazy block by the right tackle here—Mouton fought inside of the guy, sealing himself. The sad thing is that Kenny Demens has cleared the trash from the Sagesse double and is showing up in the hole:
If Mouton is outside the guy he's almost certain to tackle short of the first down…
…but he's not:
Another third-down touchdown from the ten given up by a combo of players but especially one in particular; another four points on the board because of a basic mental error from a Michigan defender. This one is ten times more frustrating than Courtney Avery's because Mouton is a fifth year senior who's been doing this his entire career, including earlier this year against UMass on another egregious play that was picture-paged.
- Either Mouton has suffered the worst kind of coaching malpractice during his career or he's just not all there. Or both, I guess. He should not be making this mistake. He has made this kind of mistake dozens of times. Maybe there's something in the scheme that makes it confusing as to when he's supposed to be the contain guy, but I don't think so. WLBs should know this as part of their DNA. There's a theory floating around that Mouton has gotten used to playing next to Ezeh and now assumes he has to do everything himself and may get all clueful now that he's playing with a linebacker that usually shows up in the right spot at the right time, but I don't think so. It doesn't matter who you're playing next to since hopping inside that tackle is guaranteed doom.
- The defensive line didn't do the linebackers any favors… Other than some sporadic help from RVB and Roh this was par for the course. Here the NT is Sagesse instead of Patterson but the end result is similar to what happened all day: effective combo on Banks gets him passively single-blocked and gives Mouton a tackle to deal with. Combo on whoever the NT is crumples and/or seals the guy.
- …but could this actually be something resembling okay from Sagesse? It's not good by any stretch of the imagination but the reason Demens is flowing into the gap unblocked is because the C could not pop off of Sagesse after shoving him downfield. That mess falls in a heap, meaning that the nose has taken out two blockers. I didn't plus the guy because I thought it was more luck than anything and ending a play on your knees two yards downfield doesn't seem like a strategy sustainable in the long term. I didn't minus him either because he kinda sorta just managed to do his job.
- More good Demens play. He doesn't get blocked but because Sagesse is blown off the LOS this isn't the world's easiest scrape. He makes it and should have an opportunity to tackle if everyone else does their job. It's impossible to say whether or not Ezeh would have made the same scrape, but we've seen enough of him to know that he doesn't do it consistently. He might be standing right where he was at the snap, or he might not have the agility and recognition Demens does to get around the garbage. (FTR, Demens did not get a plus here; Mouton was –2, Banks –1.)
We don't know whether or not Demens does execute this consistently, or whether his run-fill gusto is exploitable with misdirection or play action. His Iowa game was promising, though. I'm sure he'll have some wobbly games during the second half—Iowa was not one. I repeat my stat of wonder and alarm: when Demens was on the field runs that did not pop outside contain because of mistakes by Mouton, Black, and Banks averaged under 2.5 YPC. This happened essentially without Mike Martin. Whatever problems existed with the run D had nothing to do with him.
Mouton, meanwhile, is incredibly frustrating. This year he's turned "big positive, bigger negative" into "big negative, bigger positive" but I'm not going to spend 2011 pining for him. Michigan can't and shouldn't pull him since he makes a lot of good plays; I don't think Michigan's run defense is going to suffer greatly without him.
