If he can be a 5th rounder or better it'd be hard to come back. As much as id love for him to come back I wouldn't blame him If he would go. Rbs careers are just so so short that once your able to start your nfl clock almost anyone in that world would advise him it'd be not only ok to go but it'd be smart. Look no NFL team is going to draft him as a bell cow like Dalvin Cook or Fournette will be. He will be asked to be used like a Darren Sproles type. He would have a chance to get 5 to 10 touches a game or so. Be it as a 3rd down guy in the kicking game or have special packages for him (something Iowas staff doesn't seem to know how to come up with) He wouldn't be the smallest guy that's ever played. I think on the right team/coaching staff he could do well....Either way I'm a fan of his he seems like a good kid.
