Bronco left because he got tired of being a "bishop, an marraige counselsor, a honor code counselor, a mission president, etc." He is so much happier at Virginia, because all he has to be is the Head football coach. 

Dumping the staff would rock the boat even more. If BYU wins the bowl, which I believe they will, that'll be 7-6. Kalani gets another year. Progress is being made, albiet baby steps. Think of all the freshman that played this year.
