He'd burn up his senior year on the bench at Utah or any other P5 school if he asked for a transfer this late; he doesn't know the system. Not even sure Utah would have a scholarship to offer this late. The only way he transfers is to a G5 or JUCO where there's a major need or if he's a lot less intelligent than I thought.
If he stays, next year he'll be the most prominent linebacker on the team. He'll start. He'll know the system. He'll have time to get bigger, stronger, and faster. Seems like them best option at this point. He has no one to blame but himself.
