It is changing into exactly what he is ... a back that can run up the middle or outside ... a back that can pass block or lead block in a two back set ... a back that can execute the screen or the sweep ... a back that can slip into the slot and run the route tree.

There isn't another RB on the roster that is further along in that trend than mark Ingram. He isn't worried about ANY of the others supplanting him at this point.
