Substitution notes: Patterson played the entire second half and big chunks of the first as it was clear that Mike Martin was not recovered from the late MSU cheap shot. RVB never came out; Black cycled in for Banks, mostly on passing downs. Fitzgerald got a few snaps as Roh's backup. At LB, Demens played the whole way except for the first few plays of Iowa's third drive; Thomas Gordon and Carvin Johnson rotated with Gordon appearing to get most of the time.

Formation notes: Okay, Greg Robinson, I believe you. This defense is indeed "multiple." Michigan played a little stack, a lot of it with two deep safeties:

That's a stack with the bandit in a deep half. I called it "stack two deep."

Michigan played some 4-3, and they played a lot of a 3-4:

This is different from a 4-3 with a standup DE because of the alignments of the DL, who are head up on the C and Ts. That's just a 3-4, straight up. Early in the game they were using Floyd as the WLB, but after a couple issues with that they put Kovacs in the box and used Floyd as the overhang guy. This appeared to be a response to Iowa's heavy use of twins.

The past two weeks the defense has used more 3-4 and 4-3 than stack, FWIW, so its heavy deployment in spring and fall may be an artifact of the team it's going against. Against spread outfits Michigan has been almost all stack.

Show:

Demens? Demens Demens? Is it really pronounced "Demons"?

Sounds like you need a—

Chart.

Chart.

Hahaha!

No, seriously.

You're no fun.

[RPS is "rock, paper, scissors." Michigan gets a + when they call a play that makes it very easy for them to defend the opponent, like getting a free blitzer. They get a – when they call a play that makes it very difficult for them to defend the opponent, like showing a seven-man blitz and having Penn State get easy touchdowns twice.]

Losing Martin—even when he was in the game he was obviously not Martin—crushed the DL just like you would expect. With Martin out the only half-plausible rushers on the line are RVB and Roh, if he's coming, and since the other two guys can be single-blocked no problem all you have to do is leave one guy in to double the other two, and while they're not terrible they're not BG or Martin. Add in Patterson and Banks getting clubbed in the run game and it adds up to a very rare—possibly unprecedented—negative day for the DL to go with a –7 pressure.

The linebackers we'll get to in a sec; the secondary is just a debacle. Avery's a part of that but it's not like the starting corners are any good, either. The two slants Floyd gave up were incredibly frustrating, the second moreso than the first because you should be able to play off the receiver and tackle the slant for less than nine yards.

Demens. Wow.

Yeah. Watching the game live I thought that he was an obvious upgrade over Ezeh but expected that when I went over the game in detail I'd find he was at fault for some of the longer Iowa runs or third down conversions, or had messed up in some way that had gone unexploited. I didn't. I found little things that I thought were good plays I hadn't seen live, like this:

There Patterson gets insta-scooped and the center is going to club the MLB five yards downfield and the tailback will get a nice gain, except this is Demens and he reads the block. He attacks, turning the center into the clubee and turning the Iowa line into a mass of bodies without a gap in it. Floyd comes up to tackle.

How many times did Iowa RBs find themselves facing a line with no penetration and no holes in it? Several. How many times did previous Michigan opponents face this? Essentially never. Good DL play with crappy linebacker play yields a lot of penetration and a lot of lanes where the DL aren't. Crappy DL play with good LB play is this, a bunch of bodies on the line with no windows to squeeze through.

This doesn't look like much but he's there when Mouton forces it inside:

This was 100% consistent. When plays were turned back inside Demens was there.

Meanwhile, this was the only instance where it seemed like he was burned on play action:

Is that really on him? It seems like it's mostly on Gordon being way, way too deep. Demens was eight yards deep on his drop and I can't see any way that him being better at pass D stops this play. I minused him here, but I'm not sure if he deserves it.

He's the undisputed starter now. Not to pile on the guy, but this is the first thing that will pop into any Michigan fan's head when Obi Ezeh is mentioned for the rest of time:

Fair or not (pretty much fair), that's the coda.

So if Demens was such a ninja how did Iowa rack up all those yards on the ground?

Mouton. I know he came out +3 but I'm annoyed with that, and annoyed with him. There will be a picture pages later today or tomorrow discussing Iowa's 11-yard touchdown run on which Mouton fought inside a tackle and gave up the corner when Demens was scraping to the hole; most of Iowa's long runs were on plays where Mouton did not contain the ball and drive it back inside. Here's one:

Black didn't do Mouton a ton of favors but he can't get upfield and essentially block himself there. Force it back inside and it might be a big gainer; let him outside and it will be.

On the same play I gave Demens a minus half because he bit up, but I was torn about that since he sees Sagesse chopped and knows there's going to be a cutback lane, then doesn't get locked up by the OL. He seems like a smart player. Mouton doesn't; he makes a lot of great plays but he is still consistently making errors similar in severity to Avery's zone messes. Avery's a true freshman. He's a fifth-year senior. He is better this year, but he's still mistake-prone.

Another example:

Here a window opens up in the line. I know what Demens would do: hit it. Mouton gives up backside contain by attempting to scrape over the top on a jammed-up play and gives the cutback lane. The #1 answer to the question "why do we give up so many cutback runs" is Mouton.

Another example:

These four plays represent 54 of Robinson's 110 or so yards that came with Demens in the game. On plays where the rest of the D allowed him to be involved Iowa averaged under 2.5 YPC. This is how you get +8 as an MLB. Mouton came out positive because he made some impressive plays and blame on those outside runs was shared with the DL; he was obviously Michigan's second-best LB on the day.

Why the hell didn't they put Demens on the field before?

Man, I don't know. I assume part of it is disciplinary; I heard from a good source that he got in some minor trouble in the offseason. Not trouble enough to actually warrant a suspension or justify leaving him off the field for the first half of the year, but something that would provide some drag as he attempted to pass a senior returning starter. That's the only explanation for the Moundros dalliance. Obviously they were dissatisfied with Ezeh; to go to a converted FB walk-on when you've got Demens in your pocket there has to be something off-field, whether it's attitude or whatever.

And then Obi had a game or two where he was moderately okay, and GERG apparently really likes him, and oh hell, I don't know. As you're bitching try to remember that this is the vastly preferable scenario. For the rest of this year and the next two years Michigan will have an upperclass starter who looks competent instead of yet another freshman or position switch guy.

Isn't this all a little too good to be true?

Yes. I mean, Cam Gordon imploded as soon as I said "I like the kid!" I've just doomed Demens.

What about the other ten guys?

Right. Something more specific?

That's a horrendous performance from the DL, isn't it?

Yes. For most of the day Stanzi's experience in the pocket was this:

Martin is the Woolfolk of the defensive line and not having him made the line 70% as bad as the secondary. (The secondary doesn't have an RVB and the line isn't starting freshmen.) Patterson does well to not get blown up by a single block and Banks is reason 1B for all the cutback runs; neither can sack the quarterback unless given a gilded invitation (Banks got credit for one for Stanzi's inexplicable run OOB, FWIW). There's nothing surprising here given what we know.

The secondary?

Is the secondary.

Heroes?

Yeah: Kenny Demens. Also, RVB and Roh did yeoman work against extra defensive attention and still came through to the good.

Goats?

All cornerbacks save Talbott and Mouton, +3 be damned.

What does it mean for Penn State and beyond?

If Martin's not full go we're permadead, but you knew that. Secondary is dire, but you knew that.

Demens's emergence is huge. If he can maintain this level of play Michigan will have gone from some of the worst linebacker play in the league to average-ish, or even better, and they've filled a gaping hole in the 2011 and 2012 defenses with the upperclass years of an effective player. There is a nonzero chance that Michigan can kinda-sorta shut down Penn State's rushing attack. If Demens comes through the next three games unscathed Michigan just picked up a huge win.

Freshman quarterbacks ahoy!
