This was the one beacon of hope on the defense, provided mostly 4s. The preview was extremely high on one Mike Martin:

… it's time for Martin to make the same leap Brandon Graham did between his junior and senior years. I can't offer anything more powerful than this wonderfully ungrammatical assessment from Jibreel Black:

You look at the rest of this defensive line and there’s a lot of talent there, but is there anyone in particular that you look at and say, ‘wow man this dude is better than I thought he was? ‘

“Not necessarily better than I thought he was, because I know all of them are good, but when I see some plays that Mike (Martin) makes in practice, I be like dang. His explosiveness, his technique that he uses. You can tell the work that he put in with it.”

I hope to be like dang for large sections of the season. … I'm not sure if Martin will be on All Big Ten teams after the year, especially at a position at which statistics don't always tell the tale, but I'm confident in asserting he should be on them.

The preview misidentified the Banks/Sagesse combination as the other defensive tackle when it's primarily been Banks on the field and he's always a defensive end when Michigan goes to its four man front. The two were regarded as meh interchangeable pieces on par with Rondell Biggs, the Other Guy on Michigan's ridiculous '06 line. In sum:

Michigan's formations will go some way to determining which player gets more time. In three-man lines Sagesse is clearly going to be a pass-rush liability as a defensive end, but when Michigan goes to four (or brings in the "double eagle" package with the DEs lined up over the opposition guards) Sagesse's got more heft. I wouldn't be surprised to see both lifted for Jibreel Black or maybe Craig Roh on passing downs.

Take your pick of adjectives: workmanlike, yeoman, gritty, etc. Expect something okay here; the upside is low, but so is the downside.

Backups were not encouraging: "Everyone is worried" about Will Campbell's ability to stick after getting lit up in limited time as a freshman and falling behind Adam Patterson on the depth chart. Patterson was not projected to be good:

He'll play; I don't think he'll be much good. The dropoff after Martin will be similar to that Michigan experienced when Graham came off the field, though less severe since Martin won't be Graham and the backup is at least a senior.

Ryan Van Bergen and Craig Roh were treated as defensive ends, something that's been true for them about 50% of the time. When Michigan goes to a four-man line Roh is the weakside DE; he's a linebacker otherwise. When they're in a three man line Van Bergen is the strongside DE; he's still a three-tech DT otherwise. RVB in a nutshell:

Van Bergen knows the position [DE], was recruited to play it, and is entering his fourth year on campus with a season as a solid starter under his belt. Least useful phrase ever: he's not going to be Brandon Graham. Mitigating phrase: but he should be solid. At a spot more amenable to pass rush and with more experience, RVB should brush up against double-digit sacks and see his UFRs climb into the consistently good realm inhabited by, say, Tim Jamison as a senior.

Roh was given a 3 as the deathbacker and dubbed "the Denard Robinson of the defense," which was true last year but cannot be true this year since Roh hasn't decapitated three opponents.

The catch in the Craig Roh explosion is this niggling move to the 3-3-5, where he's a strongside linebacker. …No one's sure how much Michigan will be running a three man line this fall but it will be some, which will give Roh the ability to attack from surprising angles and use his vertical speed to get into the backfield. It will also expose him to play action, counters, and other plays he's not used to dealing with much that can take advantage of the inability to change direction that had everyone projecting him as a defensive end despite being linebacker size. Now, you could just say he'll blitz all the time but that would get predictable; it would also impinge on Jonas Mouton's ability to do the same thing, and Mouton's a guy who has the exact same strengths Roh does. They'll have to split the fun bits where they tear into the backfield.

All this makes it difficult to project what Roh will do this season. A guess: doubling his 7.5 TFLs and significantly adding to his two sacks is a good bet. I don't think he'll be a crazy star just yet, but I expect to be saying the same things about him next year that I'm saying about Mike Martin this year.

Fast forward to NOW!

I be like dang about Mike Martin. Fears about turning him into a mediocre nose tackle proved unfounded. The move to the 3-3-5 has actually freed him up to slant past offensive linemen and splatter running plays or unleash thumping pass rush up the middle. Despite essentially missing the Iowa game he's amongst the team leaders in TFLs with 5.5 and has 2.5 sacks. He's got 23 tackles, as well, an impressive 16 of those solos. He went into beast mode against Notre Dame, racking up an 11.5 and proving himself too quick for one guy to do anything with:

He followed that up with an +8.5 in his toughest matchup to date against Michigan State:

At the end of that game he got hit with a cheap block and sprained an ankle that saw him play like a ghost of himself in the Iowa game. He eventually missed the second half.

Van Bergen has also checked in around expectations. He wouldn't look out of place on Michigan defensive lines of yore when the defense was actually good. He's not making a ton of tackles (just twelve) but has two sacks and four of Michigan's eleven QB hurries on the season. He's been hovering around the +4/+5 area that's a decent to good day for a 4-3 DE, and since he's not a 4-3 DE those numbers point towards an above-average player. He was even an impact player against MSU with a drive-killing sack and solid play against the run. He tied Martin's numbers on the day.

The Banks/Sagesse combination has disappointed. Sagesse hardly sees the field. Moving him to the outside when he seemed like a functional DT last year is and was a strange move. It's hard to imagine he'd be less effective than Patterson, and with Michigan moving towards four-man lines against pro style offenses he could have reprised his role from last year as an okay backup to Martin. Though Banks leads the team in sacks that's because Ricky Stanzi inexplicably ran out of bounds, Indiana busted a protection, and one of the nonconference snackycakes was a nonconference snackycakes. He delivers no pass rush and often finds himself single-blocked effectively. Michigan's been trying to get freshman Jibreel Black more playing time in response; they're finding it hard to keep him on the field because right now he's horrendous against the run.

Finally, Craig Roh has not made the hoped for leap in production. This is largely not his fault. He's not a linebacker, he's a weakside defensive end, and when you put him in space he makes a lot of bad zone drops and is often beaten in one-on-one situations by far more agile receivers. He's okay in man coverage against a tight end, but he's hovering around 250 pounds—he is the wrong kind of mismatch against a WR.

Michigan put his hand on the ground against Notre Dame to good effect…

…until Brandon Herron went out with injury and Michigan felt forced to put him at linebacker. Roh had a +11 on the day; Herron hasn't seen the field since and Roh's been stuck at LB in Michigan's 3-3-5. As a result, he ended up solidly negative against Indiana. The pro-style attacks of MSU and Iowa saw him put his hand on the ground 70-80% of the time; Roh ended up in the +4/+5 RVB zone after both games.

Fast forward to LATER!


At this point it's obvious that Will Campbell is not going to have an impact on the defense this year, so things are settled and relatively static at three positions.

Martin's ankle is 90% of the variance in future performances from the Michigan defensive line. Since he was healthy enough to at least try against Iowa and has had a bye week the assumption/hope is that he's shaken it off and can resume his backfield-terrorizing ways. He should continue to perform at an all conference level; his numbers will probably come up short because no one can cover long enough for Michigan to get sacks.

Roh and Van Bergen are a level of play down from Martin; at this point in their careers they're both good Big Ten players but not stars. Roh should be improving more quickly than anyone else on the line because of his relative youth. Hopefully by the end of the year he can make more impact in the pass rush and Michigan can reliably get pressure with four.

The strongside DE spot currently manned by Banks could see a late switch as Michigan coaches keep trying to get Black playing time. Unfortunately, he's an obvious liability in the run game and opponents will have scouted this by now. They've already installed a run/pass platoon there, so all that's left is to throw Black in the game and hope.

Prediction accuracy to date: Complicated by the error when it comes to positions. RVB is about a 4, as is the combination of Martin and Banks. Roh is about a 3. If I'm ranking them by actual position the strongside DE is a weak 2, the DTs a 5, and Roh still a 3.
Level of play relative to prediction: About right; main error was being too optimistic about the Banks/Sagesse combo.
Expected level of play for remainder of season: No change unless Michigan manages to get Herron back and decides to roll with Roh as a 3-3-5 DE, something that will only be relevant against Purdue and maybe Illinois.

I would love to see Roh in the weak-side DE position permanently. Who is behind Herron on the depth chart? For some reason I am unable to recall. I agree with Brian, Roh is a big LB and isn't able to plant and make cuts to tackle RB and WR one on one as well as some others. However, his ability to explode off the ball and get to the QB or RB in the backfield is a huge asset. I hope to see him with his hand down a lot more and hopefully when Herron is fully ready to go he will be.

Brian in your analysis you forgot to mention Mike Martin is on pace to set  the new Michigan record for "most times to force a hold from the donkeys on the other teams oline that does not get called".   He moved ahead of Glen Steele in the MSU game and is only 5 behind Brandon Graham and Mark Messner  with 5 games left.

I agree with Brian that Roh as a rush lineman makes far more sense than him at LB, but I also don't see why the team continues to stick with the 3-3-5 instead of just putting 4 guys on the line and bringing down a safety against the run (likely Kouvacs).  Roh is rough in space but a great behind-the-line guy, while Kouvacs can tackle reasonably well and could be protected somewhat by Mouton and Demens.  I know everyone is worried about Kouvacs being trucked by RBs and linemen, but you give up the same yards if Roh is trailing WRs or shifty RBs all day.  Might as well maximize the talent on the field instead of maintaining the illusion of a standard defensive set.


October 28th, 2010 at 3:55 PM ^

It's Kovacs, sorry just had to. Anyways, that's pretty much what we have been doing, or at least it seems like it. Since we have been playing more pro style offenses, we have moved to more 4 down lineman instead of 3. Kovacs has done a pretty decent job and I expect us to remain doing it. Hopefully Herron comes back soon and is able to allow Roh to go down on the line more.


October 28th, 2010 at 5:13 PM ^

I agree.  I just think that needs to be the base defense going forward, not a situational defense for pro-style teams.  Playing Roh in the defensive backfield against spread teams won't work, and the past few weeks have shown that the 4-3/3-3-5 stack/whatever is more effective than the 3-3-5 trotted out in the early part of the season.

Thanks for the spelling catch.  For whatever reason, I always want to put the "u" in there even though I know it shouldn't be.  Makes him sound more British/Canadian, I guess.

It seems like well will be set at d-line for a while. I know my way around catholic central where d-end Matt Godin goes and it seems that if or when he gets a M offer he will probably commit. Today i heard a rumor, maybe Tom or Brian can confirm this that Danny O'Brien, a guy that would be a big get in the '12 class is shadowing Godin tomorrow at CC. It seems like Danny is thinking about transfering to catholic central to play on a better team since powers was 1-8 this year and CC is a far better team and against better competition. That being said this looks good for us because since Godin is a potential lock and if O'Brien transfered it looks like he will commit too.
