Deboer from Washington would not be a good fit, imo. But I really don't know who else you bring in. Bama is currently a victim of their own success. No one wants to follow in the footsteps of the GOAT, because the expectations are insane. They would almost be better off signing some hotshot coordinator like Warren Ruggiero or Garrett Riley, hungry to make their own name, rather a coach like Deboer who would be chasing the money.
I imagine whoever they hire won't be around at the start of year 4. The first time he loses 3 games and/or loses to Auburn, Bama fans will be calling for his head.
DeBoer has a helluva coaching record. Reminds me of Brian Kelly when ND nabbed him. All he does is win everywhere he goes
