I am not jumping on the bandwagon. I've said he was over-rated for years. He does not win at a "high level everywhere". He won the Pioneer League, twice. He never won the Pac 12 and has not won the Big 10. In fact he never even won his division outright. Shaw is the far more successful Pac 12 coach and it isn't close.

He is far better suited for college ball because he is so **** weird that he wears people out. He needs the player turnover because they tune him out after a while. His problem is that he wants to build his college program around the QB. That rarely works as most college QBs aren't that good and the good ones go pro. What you saw today was yet another example of Michigan without an actual identity. Beating a Harbaugh team is pretty simple - keep the first half close, run the ball, wait for them to panic, and you'll be in it at the end.
