I don't believe any offense that averages 30 or more pass attempts over the course of a season is an offense that suits AJ Bush. Fuentes likes to stretch the field, and is a all three levels type of offense, which I don't see Bush fitting. With that said, Fuentes is known for developing dual-threat guys so maybe you're right!
Personal opinion, this has more to do with their QB leaving early for the draft and VT looking to fill a roster spot late in the game. I wish AJ the best, he was always a class act at Nebraska.
