The main reason I would entertain a move for him...and again...not saying I would..
He would add a bit to the passing game as well. Also, coming off the injury it sometimes takes a full year to bounce back to normal. We would potentially have 1st crack at resigning a guy that flashes big play potential in both the pass and run games. Yes the 1 year price tag is high and he has had injury issues. Both big red flags. However if fully healed he could be an excellent back to combine with Motor.
It could be very much like when we made a move for McCoy...if the initial investment is low enough at a late pick it may make sense for both sides
