John Cooper's first three years at Ohio State:
1988: 4-6-1, with blow-out losses to Pitt (42-10), Illinois (31-12), and Indiana (41-7, perhaps the low point of the program during my lifetime); also lost to Michigan
1989: 8-4-0, with blow-out losses to Southern Cal (42-3) and Illinois (34-14); also lost to Michigan and the bowl game
1990: 7-4-1, with another loss to Michigan and another bowl game defeat (to Air Force!)
Three-year totals: 19-14-2 overall (.571 winning pct), 13-9-2 in the Big Ten, 0-3 versus Illinois, 0-3 in The Game, 0-2 in bowl games ... but he did get our last win against an SEC school (LSU in 1988, 36-33).
Coop's next two years were little better:
1991: 8-4-0, another loss to Illinois, another loss in the bowl game, and a complete ass-kicking by Michigan (31-3, that was the Desmond Howard Heisman pose game)
1992: 8-3-1, another loss to Illinois, another loss in the bowl game, and a tie against Michigan ("one of our greatest wins ever....")
Five-year totals: 35-21-3 (.619 winning pct), with some improvement overall, but 0-5 versus Illinois, 0-4-1 versus Michigan, and 0-4 in bowl games
Cooper was left with a bare cupboard ("too many slow white guys") after taking over for Earle Bruce (who was a nice guy and a true scarlet Buckeye, but couldn't recruit outside the state of Ohio and made JT's offense look positively flashy by comparison), and he didn't really get the program back into prominence until 1993, when the team embarked on a great six-year run (62-12-1, .833 winning pct, Rose Bowl win and #2 finish after 1996 season, Sugar Bowl win and #2 finish after 1998 season).
If we had had the internet and "instant media" back in 1990 like we have today, would Cooper have made it past year three? I say probably not.
Not every program is a quick fix. Michigan does not have a built-in recruitng base like Ohio. Michigan is never going to get a class of home-grown talent like Ohio State got in 2002 with Hawk, Smith, Mangold, Sims, Carpenter, Clarett, Kudla, Downing, Datish, Pitcock, Richardson, Zwick, and Antonio Smith (all 13 were starters, 8 were All Big Ten, 4 were All American, 2 were major award winners). Michigan (like Ohio State) is a tough sell for southern kids, and Michigan does not have recruiting roots in Florida like Ohio State does (and we can thank Coach Cooper for that).
The question isn't really, Was the cupboard bare when Rich Rod got there? (It wasn't). The question isn't really, Has Rich Rod turned the program around (He hasn't). The questions are, What is the ceiling for Michigan under Rich Rod? Can he ever put together a string of 10-win seasons like Coop did? Will he ever challenge for a national championship like Coop did twice in three years? Will his schemes work in the Big Ten? Will he ever "get it" when it comes to The Game?
Three years is not enough time to fix a Michigan program that was entering a down period. But is Rich Rod the guy to get them back to respectability? Or is struggling to go 8-5 going to be the norm for him?
