"You look at the style of runner that Chip wants in his offense and even though Shady is one of the best backs in the league, he's not necessarily what Chip is looking for all the time," Jenkins said. "Chip thinks he's a great running back, he knows his talent is there, but our (system) is really predicated on downhill, somebody who is going to hit the hole every time. It's about getting up in the defenders face as fast as you can and that's not necessarily Shady's running style."
