that has been severely underfunded and under resourced, and he has had less than stellar staff, including his first offensive staff encouraged by his AD, none none of which were even coaching in college before or since (as far as I know.)

The resources are up, the staff is better. He may be average with major weaknesses, but he is not in over his head. In fact with such a lack of resources in the past, I'd say it was BYU who was in over its head for a while.
