What does his time at Central Michigan have to do with him here? Do you think if he would have stay at Alabama, they would have had a bad offense?
That is like saying, what did his time as OC at Arky or QB coach at Bama have to do with him here. As a HC, you run the program exactly as you want it. He was running the offense exactly how he wanted and it wasn't good, much worse then the prior coaching staff.
I just find that comment intellectually dishonest because past performance doesn't suggest that to be the case.
FWIW, I'm not saying the hire was good or bad.
