There are so many signs of this that it is not an opinion but a fact. He is a spectator on the sidelines. Offensively, I don't think he has a clue as to what is going on. He looks lost and nervous. He says in his post game presser that the scheme was not the problem but the execution was. He has no input whatsoever. A few more games like this and he will have lost the team, if he hasn't already lost it.
He is a great person, a Notre Dame man, and a wonderful recruiter. But as a head coach, he is failing miserably. He is in way over his head.
