I think it is a combination of things: 1. The RB position has been devalued in the NFL(which I think is a mistake) 2. He is a small back at 5'9" 191lbs. so people have durability concerns( although it didn't seem to hurt too much in college as he was a high snap back who hasn't shown any issues with injury, thanks in part to knowing how to take on contact.) 3. There are concerns that he doesn't have that second level speed(but he has burst to get through the hole and get to the second level. He kind of reminds of James Stewart who played with the Lions years ago. Same concerns, but you know what, all the guy did was get 4yds/carry and move the chains.) This guy should have been drafted higher and I think we got a steal.
