Brian Kelly is apparently considering moving Theo Riddick back to RB after the season-ending injury to Jonas Gray (per Eric Hansen on Twitter). 

In my opinion, Riddick hasn't had the same explosiveness this year or at any point since the ankle injury in 2010, but some experience depth at the position could be welcomed.  Also, it opens up a spot for Roby Toma to get plenty of reps in the slot. 

What are everyone's thoughts?
