I keep mentioning Michigan's disastrous 2010 class and how Michigan's attrition has slowed considerably since Brady Hoke was made head coach, so I thought I'd lay that out in pixels.

It'll be interesting to see what happens over the next few years—Hoke's attrition rate will go up as certain guys find themselves buried on the depth chart and his classes have more time to pick up career-ending injuries, but so far so good.

Starter-level contributors are in italics.

[UPDATE: I corrected some errors. Hopkins left football, Teric Jones was injured, Hayes was an RR recruit, italicized Raymon Taylor.]

2009

This was a Rodriguez class, his first full one. Only redshirt seniors are still around from it.

Jeremy Gallon, Justin Turner, Taylor Lewan

Enrolled: Jeremy Gallon, Taylor Lewan, Quinton Washington, Michael Schofield, Cam Gordon, Fitz Toussaint, Mike Jones, Thomas Gordon, Brendan Gibbons

Played Out Eligibility: Will Campbell, Craig Roh, Denard Robinson, Vincent Smith, Brandin Hawthorne.

Transferred for PT (3): Vlad Emilien, Je'Ron Stokes, Isaiah Bell

Academics/Not Being Nice (3): Justin Turner, Tate Forcier, Adrian Witty

Injury (1): Teric Jones

Left Football: N/A

This is actually a high-quality outfit with 17 of 24 kids completing their eligibility or about to do so. Michigan got ten starter-level contributors with the prospect of adding an eleventh in Cam Gordon this year, and there should be four to six NFL draft picks out of this group when it's all said and done.

The biggest bummers here are Justin Turner's inability to scale depth charts that were below sea level for most of his time here, and Tate Forcier's spectacular flameout. That's not too bad for a large class.

2010

All Rodriguez, during his under fire period.

Dorsey, Gardner, Vinopal

Enrolled (9): Richard Ash, Courtney Avery, Jibreel Black, Drew Dileo, Devin Gardner, Jordan Paskorz, Jake Ryan, Jeremy Jackson, Will Hagerup(?)

Transferred for PT (6): Ricardo Miller, Cullen Christian, Marvin Robinson, Carvin Johnson, Jerald Robinson, Ray Vinopal

Academics/Not Being Nice (5): Demar Dorsey, Antonio Kinard, Austin White, Davion Rogers, Conelius Jones

Injury (3): Terry Talbott, Terrance Talbott, Christian Pace

Left Football (3): Ken Wilkins, DJ Williamson, Stephen Hopkins

The disaster class. Four kids never showed up on campus because of academic issues—which is four more than Hoke has had in two and a half recruiting classes. A fifth, Austin White, was immediately a problem child and didn't make it to fall after enrolling early. While Rodriguez can't be faulted for losing the Talbotts or Christian Pace, he can be faulted for making Pace the only(!) offensive lineman in this class.

Michigan also brought in an assortment of guys who busted almost immediately. Cullen Christian was out the door after one year, as was Ray Vinopal. DJ Williamson quit to go run track at Akron. Ricardo Miller hung on a little longer but was moved to tight end quickly, which was pretty much the death knell.

Finally, hanging over this class is the bizarre specter of guys who were getting playing time but left anyway: Christian, Vinopal, Johnson, and Hopkins were all seeing snaps—though Hopkins did seem to lose his job after moving to fullback—early, and then left.

Meanwhile the few guys who are still around are Jake Ryan, Devin Gardner, Jibreel Black, and some role players. Three starters out of 27 players, and 8 or 9 guys who are even here right now, depending on how you want to classify Hagerup.

2011

Frank Clark 50 pounds ago, Chris Barnett, Tony Posada

This was the hybrid RR/Hoke class in which Hoke found himself with three weeks to pile ten guys in. Late Hoke pickups are denoted with H.

Enrolled (13): Justice Hayes, Brennen Beyer, Raymon Taylor(H), Chris Bryant*, Blake Countess, Delonte Hollowell, Frank Clark(H), Thomas Rawls(H), Desmond Morgan, Russell Bellomy(H), Keith Heitzman (H), Jack Miller, Matt Wile(H)

*[Bryant actually committed after Hoke was hired but had been favoring Michigan so long that Rodriguez deserves the credit there.]

Transferred for PT (1): Tamani Carter(H)

Academics/Not Being Nice (2): Chris Barnett(H), Kellen Jones

Injury (1): Antonio Poole(H)

Left Football (3): Chris Rock (basically: is walk-on at OSU now), Greg Brown, Tony Posada.

Beset on all sides, Rodriguez struggled again in 2011. He locked down Brennen Beyer and Blake Countess and found an excellent sleeper in Desmond Morgan, but that's about it. He recruited three guys who didn't make it through year one at Michigan—Posada in particular showed up for a cup of coffee only—and  missed out on Lawrence Thomas, DeAnthony Arnett, and Anthony Zettel in-state. He did put Michigan in a good spot for Chris Bryant, who technically committed after Hoke was hired.

By the time Hoke came in he had ten spots to fill in three weeks and he was swinging wildly. He found some hits: Wile, Clark, looking like Taylor and Heitzman. He also brought in Chris Barnett, a tight end who'd had more high schools than years in high school. He immediately flamed out and took Kellen Jones with him; Jones would later flame out at Oklahoma as well. Minnesota decommit Tamani Carter also couldn't hack it quickly and departed; Antonio Poole was hewed down by injury.

13 of the 20 guys enter their true junior or redshirt sophomore seasons, and while there's significant attrition already almost all of it can be attributed to Rodriguez recruiting some guys who saw the (depressed) talent level at Michigan and said "noooope" and Hoke having to cram ten guys in his recruiting class in three weeks time.

2012

Redshirt freshmen and sophomores.

Enrolled: 24 of the 25 guys have made it to the beginning of year two.

Injury(1): Kaleb Ringer.

Hey look, everyone qualified and nobody was so patently out of their depth that they transferred out after one year.

I am filing Ringer as an injury issue, since I have it that he underwent serious knee surgery that robbed him of his athleticism. He chose to stick it out at a lower level instead of retire.

2013

All are qualified and enrolled. None have committed to the University of Awful Rap.
