I love Scheelhasse, and think he's a great coach and recruiter.
I'm nervous about having a first time coordinator in charge of a unit that was already struggling in game planning, execution, and game management.
It's possible Scheelhasse was getting looks from other schools to be OC, and only way Campbell could keep him is by promoting him. If that's the case, I agree with the move.
I'm 99.9% sure that was the case.
