To be honest I'd be surprised if he didn't go. He'll never match this season statistically.
We haven't had a Running Back stick around for his senior season in a while...I think Calhoun was probably the last one
There's a reason, Running Back is a so rough on bodies you basically have to get to the money while they are still young and able to play, they don't want to shorten an already statistically short pro career. Any running back that gets a draft eval back for the first one or two rounds should almost definitely be headed pro.
