I think Cronk can successful. He is an all around back but the offense makes him one dimensional. What makes Johnny good is he is hard to see and hard to tackle. Duran is just fast.
If this offense requires the Alabama offensive line, track speed RBs, Randy Moss like WRs and Steve Young like QBs, then I am not sure this is the right offense for USF. I like USF and I am partly delusional about it but I feel fairly comfortable those types of players are not walking through the door.
If Appalachian State can run an offense that can put points on the board against Penn State, i think USF can find enough athletes to so. There have been two Bay Made coaches that found success at USF when there wasn't much to speak of
