alternate headline: man does job
I hope this kind of analysis hasn't been done already; if so, my apologies. I was wondering, in light of Brian's analysis of the defense, if we could quantify the effect of having Mattison rather than GERG as our defensive coordinator. To that end, I have tried to quantify the effect of having Greg Robinson as defensive coordinator: the GERG effect. I looked up the scoring defense ranks of Michigan, Syracuse, and Texas for 2003-2010 (data from Rivals). They are as follows:
GERG was DC at Texas in 2004, HC at Syracuse in 2005-2008, and DC at Michigan in 2009-2010. We can therefore display the data graphically as follows (note that the Y axis is team defense scoring rank): We can also try to calculate a crude GERG effect by comparing the average rank of these defenses with and without GERG. This yields the following:
Note that positive is bad and negative is good. So GERG's Texas defense was 11 ranks better than the non-GERG average, whereas his Michigan defenses were 60 ranks worse than the non-GERG average.
To calculate the overall GERG effect, we simply multiple the differences in rank by the number of years at each school, divided by the total number of years (7), to arrive at our overall GERG effect of 29.77 [this figure has been updated]. That is, on average, GERG adversely affects the scoring rank of the defenses he is associated with by 30 positions.
If we take Brian's projection of Michigan's 2011 defense (82nd), and subtract 30 ranks to adjust for the GERG effect, we get to 52, a ranking that a number of commentators were predicting based on their "gut" feeling of player development and the new coaching staff's abilities (particularly Mattison).
Again, this is wild speculation, and incredibly simple -- hopefully it is not completely misguided. Other more advanced metrics should also be used. I am aware that there are far more variables at work that determine how good a defense is--and it is almost certain that GERG was not allowed to run his defense at Michigan. Also, it is likely that Mattison is an excellent DC, something that this analysis does not account for. I was still curious to see if anything could be done to account for the coaching change.
UPDATE: I made an arithmetical error which has been corrected. Also, I ran the same analysis with S&P+ play-by-play ratings from Football outsiders and got a GERG effect of 27.75 ranks (using only Syracuse and Michigan; S&P+ data are only available from 2005 and later).
[ed: We should be taking all of this, including my original post, with a grain of salt because of sample size issues.
That said, Michigan was an the extreme outlier because of its youth and trying to run two different schemes, one of which was something no one's ever tried before, and could expect to rebound further with Mattison--and more importantly, sanity--hanging around campus. The numbers offered here in the two posts (54 using S&P+ data and 82) seem like the ends of a range of reasonable expectations.
The moral of the story is the same one learned by the offenses of Notre Dame in 2008 and Michgian in 2009--you're going to be a lot better but still very far from good.]
[Ed-M: Bumped to Diaries]
(Click for larger)
I looked at the coaching records of new hires since 2001. There's a pretty wide spread. I looked at returing starters vs. this data but the data I have is incomplete. Hopefully this comes out. My wife is about to pull the plug on me.
I don't have time to play with the sizing here. This has some value maybe. If I come back to this I'll add more detail.
The negative 10 outlier is Stan Parrish following Brady Hoke at Ball State...
[Ed-M again: Adding some thoughts so I can get this to 200 words and bump to Diaries.
The bell curve here suggests the data are pretty solid, but a Delta of +0.5 or 1 wins for a new coach seems really really good. Reason being, look at the third chart, with the coaches who took over 12-win teams. We're not talking about replacing just fired guys, but also those who moved up or moved on after dream seasons. Michigan is in that 7-win area where only two teams improved.
So is there an advantage gained from having a 1st-year coach? This doesn't say, but it's not a massive disadvantage, which is what I kind of expected would happen.
I think this needs to show the difference between coaches replacing a fired guy (which suggests there was a level of suspected incompetence) versus a coach brought in to replace a legend or retiree, who in turn was followed out the door by most of his starters. In other words, it's gotta pull out the noise. There's plenty of that around, since we can expect the circumstances of the team that lost 10 more games from the year before had a lot more going into them than Stan Parrish (meh) taking over for Brady Hoke (RAWR!)].
The Kyle Kalis commitment was a huge deal for Michigan. With 19 commitments on board there's no reason to think they won't be sitting at 20-22 by the time the season starts. They're on a roll and that momentum should continue soon. Here's a look at what happened this week and what's happening in the future. As always you can follow me on Twitter @TomVH and send me any tips or questions at [email protected].
6'3", 220 lbs.
Farmington Hills, Michigan
Mario was one of the five commitments in Oregon for the Nike event The Opening. He, along with the other attendees, got to work with some top NFL talent while there.
I didn't run the forty as good as I thought I could. We got to work with Ndamukong Suh though. He had a lot of stuff to tell us about technique. We were doing ball get offs and one on ones. I think I did pretty good.
He also got a chance to meet some of the other Michigan commitments and do a little recruiting.
I already knew Terry and James [Ross] but I met with Erik Magnuson and Anthony Standifer. We did some recruiting. We were recruiting Sheldon Day, Danny O'Brien, and anyone that we thought Michigan wanted. I didn't talk to Zach Banner, but I heard he was saying Michigan was in his top group.
As for what he was saying to try to recruit prospects to Michigan.
We were joking around mostly, but we were saying come to Michigan. Look what we're building, look where we're taking the program and all these commits we have.
This event seemed to be a positive all around for everyone involved. All the prospects have been raving about the experience.
6'6", 280 lbs.
Magnuson was also in Oregon, but was working on the opposite side of the ball as Mario. He also got a chance to work with some NFL talent.
We got to work with Russell Okung, the offensive lineman for the Seattle Seahawks. It was cool because he's in the league but he's young enough to joke around with us. He's out there helping me and he wasn't acting too big. He was out there telling me what to do better. He talked to me about my hand placement with my punch on pass rushing. He said he liked my footwork and aggression too.
Erik was also in on the recruiting pitch with the other commitments.
It was cool to hang out with the other commitments, it was good to put a face to the name. We were all doing some recruiting. Josh Garnett is really liking Michigan a lot, and Zach Banner this is my second week in a row being with him. I'm still trying to get Isaac Seumalo.
I asked Erik the same question as Mario, what is he telling recruits as to why they should choose Michigan.
I just ask them if they want to win a National Championship. Someone said that Michigan has the number one or number two recruiting class. Look at what Coach Hoke did at San Diego State. Give me one good reason why he won't do that at Michigan. I know Coach Hoke more than anyone else and there's no reason to think he won't win at Michigan.
The other recruits were listening to the pitch, and as you already know Josh Garnett and Zach Banner are both planning official visits to Michigan.
6'2", 295 lbs.
The theme with The Opening continues as O'Brien was also at the event. As Mario mentioned the commitments were trying to convince Danny to jump on board. He spoke very highly of the event.
It was sick, they over did it with everything. They had everything for us, three barbers on hand to cut our hair, and we got to play NCAA Football 2012 which was sweet. Ndamukong Suh worked with the defensive line the whole time. During one on ones he'd pull you aside and critique you. He said that my pad level on pass rush needs to get lower and he was showing me different stances and moves.
He was obviously around the Michigan commitments and took in what they were saying.
I hung out with Terry [Richardson] and James [Ross] a lot. We hung out with them and Ron Thompson and Anthony Standifer too. They were just saying comments here and there, and talking about how many spots are left.
As for what's next for Danny, he plans on taking some more visits in the near future.
I'm going to come out with a top six here pretty soon, Michigan is definitely in there. The plan is still to take some official visits then decide. I'm going down south from the 17th of July to the 23rd. I'm going to Alabama, Florida, and Tennessee. If Godin is going to the BBQ [at Michigan on the 31st], then I'll be there too [Tom ED: Godin is going as you'll see below].
Danny is well aware of the defensive tackle situation and knows that Michigan wants Ondre Pipkins as well. We'll see how that situation plays out, but I still think there's a decent chance the coaches would take two defensive tackles if those two were Pipkins and O'Brien.
BBQ at the Big House
The BBQ at the Big House is still happening this year. It's taking place on July 31st. Still a lot of time until it happens but I've confirmed some names that will be there so far, and a few that are undecided.
Commit OL Caleb Stacey
Commit LB Joe Bolden
Commit LB Kaleb Ringer
Commit LB Royce Jenkins-Stone
Commit DB Terry Richardson
Commit LB James Ross
Commit DE Matt Godin
Commit DB Allen Gant
Commit TE Devin Funchess
Commit DE Tom Strobel
Commit OL Ben Braden
DT Danny O'Brien
2013 RB Wyatt Shallman
WR Jehu Chesson: He told me he believes he will be there.
2013 OL Steven Elmer: His father told me they will be at the BBQ. As I reported on Twitter earlier, he and his father were on campus on Monday the 10th. It wasn't a football related visit, just more to walk around campus and see things.
OL Kyle Kalis: Says he's not sure yet. I'd imagine he'd be there, but we'll see.
DT Ondre Pipkins: There's a chance, but he doesn't know yet
OL Jordan Diamond: They're not sure if they are yet, but there's a good chance they will be. His mom told me, "Any excuse to visit. We'd like to go."
RB Bri'onte Dunn: He was invited, but his father told me he doesn't know if they'll be going yet. It might help if new commitment Kyle Kalis is on hand as well. We'll see if he makes it up.
Speaking of Bri'onte Dunn. I also tweeted this, but for you non-tweeters, if Ohio State's self imposed sanctions stick with the NCAA then I'm not expecting him to leave Ohio State. However, if they get a two year bowl ban then I think that's too much for him and there's a good chance he would leave. Just something to keep an eye on. The OSU compliance meeting is in August, so we won't know what the official word is until then.
The offensive line situation now that Kyle Kalis is committed has stayed the same so far. The plan for now is to take one more lineman, as long as it is one of the elite prospects on their board. That's the plan for now, it could always change but it looks like that's what will stick.
The commitment of safety Jarrod Wilson was a win for the Michigan coaching staff. Greyshirt commitment Jeremy Clark told me that he is still 100% with Michigan despite the Wilson commitment. This sounds right since the coaches laid out the scenario to him pretty clear.
MaxPreps has moved Michigan ahead of Texas with the number one recruiting class in the country with the addition of Kalis and Wilson.
If you missed this, you can see some pretty cool videos from The Opening event.
With more new Michigan commits, we're hitting the front page after a hiatus of a couple weeks. Action since last rankings:
7-5-11 Penn State loses commitment from Jarron Jones.
7-6-11 Minnesota gains commitment from Isaac Hayes.
7-7-11 Minnesota gains commitment from Dominic Twitty. Iowa gains commitment from Jaleel Johnson.
7-8-11 Michigan gains commitment from Jarrod Wilson.

On to the full data, after the jump:
As everyone knows by now there are several Michigan commitments and targets at the Nike event, The Opening, in Oregon. You can watch some of the events tonight on ESPNU at 9pm. The first part of the week was spent with the prospects running combine drills to figure out their Sparq training score.
The Sparq score is determined by using an equation that combines the prospect's forty yard dash, shuttle, powerball* (measured in feet), and vertical leap. Here are a look at the scores for the Michigan commitments and targets, and you can also see the rest of the scores here. The finals video is here.
|DB Anthony Standifer||4.61||4.38||38||30.7||91.77|
|DB Terry Richardson||4.55||4.22||31||33.2||87.93|
|DE/LB Mario Ojemudia||5.02||4.44||35||30.1||79.29|
|OL Erik Magnuson||5.38||4.78||41||22||77.85|
|WR Dwayne Stanford||4.73||4.35||40||34.9||101.64|
|OL Kyle Murphy||5.31||4.52||42||28.3||96.21|
|DE Adolphus Washington||4.97||4.57||42.5||24.6||91.89|
|OL Josh Garnett||5.38||4.68||38||28||90.81|

|OL Zach Banner||5.54||5.34||44.5||19.6||79.89|
|TE Ron Thompson||5.27||4.51||38||25.4||75.51|
Top Three Scores:
|DB Daje Johnson (TCU)||4.34||4.01||45||40.8||146.52*|
|RB Derrick Henry (2013)||4.54||4.29||42.5||39.2||134.19|
|RB Altee Tenpenny (2013)||4.49||3.92||41||35.1||133.77|
As you can see this testing isn't necessarily set up for the bigger prospects to score high. The forty times were, I believe, laser timed also. That's at least what people were tweeting that were at the event. Take from this what you will, just interesting to see how they all stack up if nothing else.
Derrick Henry is also a 6'4", 222 lb running back. He's in the 2013 class and took second in the preliminary ratings.
Ohio RB Bri'onte Dunn only had a 40 time recorded, it was a 4.77.
*The powerball is throwing a weighted ball from their knees as far as they can.
**I believe Daje' Johnson's score is a record
The Michigan coaching staff has made it apparent that they would like to recruit a running back prospect for the 2012 class. However with the number of offers extended and prospects committed, the opportunities are becoming slim. That may require the coaching staff to look for new prospects to extend offers to, and there just happens to be an uncommitted back waiting for an offer from the Wolverines.
Muskegon RB Juwan Lewis (5'11", 208 lbs) laid everything on the line recently at Michigan's camp and is now hoping that performance will earn him an offer. I caught up with both Juwan and his father, who also happens to be his coach. Here's a look at his film and then we'll start with Juwan.
TOM: Tell me first where you're at in your recruitment, and who you've all heard from so far.
JUWAN: My parents and I are taking our time with recruiting. My dad has been taking care of everything for me and it's been a great help. My feelings right now for every school is mutual, no school is above the other. I've been in contact with schools from the Big Ten, ACC, SEC, Pac 10, Big East, Independent, and MAC schools. My parents have mainly been telling me to enjoy the process and take my time with my decision right now.
TOM: When you camped at Michigan what did the coaches say to you?
JUWAN: They've been impressed with my work ethic, and they were happy with my work outs at camp. They're very interested.
TOM: What offers do you currently have?
JUWAN: I have offers from Buffalo, Western Michigan, and Eastern Michigan.
Since Juwan's father handles most of his recruiting I also spoke with him about what's happening now and what could be coming up in the near future.
TOM: I know Juwan told me he's hearing from a lot of schools, does he have any favorites yet?
MR. LEWIS: He's getting letters and phone calls from all over. His options are open for now. Does he want to go to a Big Ten school? Probably. They're all starting to come around and talk to him. I coach so they can talk to me about him and he has a lot of letters, he has a tub full of letters from schools all over.
TOM: With Michigan specifically what do you think is next after his camp performance?
MR. LEWIS: He had a great experience down there. I've been working Michigan camps for the last 11 years. I'm injured right now so I couldn't this year. They worked him over though and he was one of the best at the camps. With them it's a waiting game. I like Michigan, I love Michigan, but I don't know if they feel like they have enough backs or not. My understanding is that Juwan could be on the backs that they would take. Until they offer him we have to keep options open. He's talked about Indiana, Northwestern is definitely a school that's right there. Iowa has contacted him. The only school that's fallen off with us is Ohio State.
TOM: Can you tell me about who he is off the field?
MR. LEWIS: He plays the drums in church, too. He's in the church band so I never have to wake him up to go to church. He does a lot of community stuff without people asking him. He's a well rounded kid that's humble. I try to make him see the other side of it. Little kids come up to him, and we're in a small town, and they look up to him. People talk about not just the football but what he does in the community, he's in honor society, and he's probably going to be around top twenty in his class. He was born in Ann Arbor, I brought him up from Ann Arbor and I took everything personal with him. I'm an educator and we focused on that with him, and I'm proud of where he's at.
TOM: Do you have any idea of when he'd like to have his decision made by?
MR. LEWIS: What I want to do is have him done by a couple weeks into the season. Have him getting an offer and just saying let's go with it. I don't want him to have to worry about anything and just have fun. That takes a lot of pressure off the kid. He only has two classes next year and he has a 3.8 GPA, so he'll graduate early. In January I want him to be in someone's system, learning their program. The academic side is why I like the Big Ten schools. It's up to him to finish his major, I know he wants to major in broadcasting. I preach with him because I know he can play football. I want him to embody the student athlete and be in the study hall as much as he is in the film room.
