Why do people equate not trusting Lee today with never trusting Lee? Obviously you keep him, because if he does catch on to the blitz pickups and the like, you've found yourself a terrific running back. Until then he's a work in progress. I think he's a perfect #3 back right now. Young guy, has some skill running the ball and learning to block, something he was likely never asked to do or coached to do in college, and some of the other finer points.
He's 24, missed all last year with an injury, so he's essentially a rookie. Why would they give up on him?
