With Signing Day and spring practice in the rearview mirror, Michigan's roster should remain basically intact until fall and possibly beyond. With the media cottoning on to the enormous hole in the roster created by the last Rodriguez and hybrid Rodriguez/Hoke/Process classes, it's time to update Attrition Watch.

2009

A last look at Rodriguez's first full class. Starter-level contributors are italicized; (sometimes projected) NFL draft picks bolded.

Jeremy Gallon, Justin Turner, Taylor Lewan

Played Out Eligibility: Will Campbell, Craig Roh, Denard Robinson, Vincent Smith, Brandin Hawthorne, Jeremy Gallon, Taylor Lewan, Quinton Washington, Michael Schofield, Cam Gordon, Fitz Toussaint, Thomas Gordon, Brendan Gibbons

Didn't Take Fifth Year(1): Mike Jones.

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 class lost a little bit of its luster every time Toussaint tried to pick up a blitz, but this is still a class you can do excellent things with as long as you surround it with other talent. It features two bookend NFL tackles, the season receiving yardage record-holder, Denard Robinson(!), and six to eight other important contributors. Your 11-2 blip is built around these guys.

2010

DOOOOOOOOOOM! Your Freep class.

Dorsey, Gardner, Vinopal

Enrolled (3): Devin Gardner, Jake Ryan, Will Hagerup

Did Not Take Fifth Year(2): Richard Ash, Jordan Paskorz

Played Out Eligibility(4): Jeremy Jackson, Drew Dileo, Jibreel Black, Courtney Avery.

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

Nothing miserably bad has happened to this already miserably bad class since August. Will Hagerup has hung on to a roster spot; Ash departed after getting his degree, as did Paskorz. That leaves three of 27 players on the roster, including the starting QB and most dynamic player the defense has.

That is of course horrendous, and about 80% of the blame should  be heaped upon Rich Rodriguez. Rodriguez struck out on tight ends and OL left and right during this period, compounding that issue with some horrible talent evaluation—of the guys who left early, only Ray Vinopal has made any kind of impact at a BCS school.

Baumgardner's article comes with a depressing Big Ten retention rate chart showing Michigan at the bottom at 26%; three teams are tied at 40% for next worst: Minnesota (coaching change), Penn State (holistic program implosion), and Indiana (coaching change, is Indiana). No one else has lost more than half their class; Northwestern leads the way at 82% with MSU second.

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 (11): Justice Hayes(H), Brennen Beyer, Raymon Taylor(H), Blake Countess, Delonte Hollowell, Frank Clark(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 (2): Tamani Carter(H), Thomas Rawls(H).

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

Injury (2): Antonio Poole(H), Chris Bryant.

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

Rawls and Bryant are added to the dead list here; the Bryant departure leaves the OL count from the 2010 and 2011 classes at a whopping one, Jack Miller. Rawls was a signing-day reach who represented Peak Fred Jackson as Michigan scrambled after the process; Bryant was a three/four star borderline OL who needed to take a lot of weight off, much like Posada. Posada showed up for a cup of coffee; Bryant couldn't remain healthy enough to stay on the field, though he did start a few games in the middle of last year.

While this class is better than its predecessor it represents the bulk of the seniors on the roster. That's a problem when you've only got 11 of them and one is an offensive lineman. An attrition rate of 45% that could still go up is middling at best, something Michigan could not afford after the 2010 crater.

2012

Redshirt sophomores and juniors.

Funchess, Henry, Kalis

Enrolled: Dennis Norfleet, Sione Houma, Amara Darboh, Jehu Chesson, Devin Funchess, AJ Williams, Kyle Kalis, Blake Bars, Erik Magnuson, Ben Braden, Ondre Pipkins, Willie Henry, Matt Godin, Mario Ojemudia, Tom Strobel, Chris Wormley, Joe Bolden, Royce Jenkins-Stone, James Ross, Terry Richardson, Jarrod Wilson, Allen Gant, Jeremy Clark.

Injury(1): Kaleb Ringer.

Michigan still has all but one guy from Hoke's first class on the roster. The departure, Kaleb Ringer, had microfracture surgery and transferred to a lower level to play.

At this point there have to be a couple guys teetering on the edge of a transfer because they can't get on the two-deep—that kind of attrition is the sign of a healthy program, not a diseased one. It's worth noting that was Michigan super, super paranoid about bringing in anyone who looked like an academic risk in this class. That seemed like a reaction to the previous two recruiting efforts; now it appears to be just their standard.

2013

Enrolled: 27 of 27.

Nobody from Hoke's second class has exited after one year.

2014

Enrolled: 7 of 16 with the rest pending. There haven't been any whispers of academic issues except with kids Michigan ends up not getting, so it's likely the class arrives intact.
