Wasn't just TVD not buying in ... Ponce, the QB coach wasn't buying in to what Gattis was trying to do. Gattis was WAY over his head and it was obvious to every coach and player. The guy DID NOT run the offense at Michigan. They promoted two other assistants ... one for game planning ... and Harbaugh had input on the actual play calling. So you have a guy with an OC title that is inept at game planning, can't scheme to his roster skill sets, and is horrible at play calling on game day. There was a total meltdown (aka cluster ****) on the offensive side of the ball. Gattis DIDNT KNOW WHAT HE WAS DOING and it impacted every single facet of the offense. UM would have been more productive without an OC last year, simply keeping the Lashlee play book and letting TVD call the plays with game planning assistance from Ponce.
