The hardest thing about the transition from college to pros for a running back isn't running the ball, that's what they do. It's pass blocking against NFL pass rushers.
Grice happens to be a very good pass blocker, and should transition very well.
Absolutely no problem with this signing. But, the kid has to learn how to block in pass protection in order to be valuable. If he only runs the ball, then it is a useless signing. ASU, he rarely had to block.
If he can block blitzing LBers or Safties, then it could be an amazing signing,
