After watching Steelers spring practices, I thought Jonathan Dwyer had a chance to become the No. 2 back. After watching camp, I don’t think he’ll make the team. He had a tough start and the coaches were all over him, then he came on a little but an unspecified shoulder injury from the first game set him back again. But there is one snapshot that stuck with me most of all. At one practice early this week, the Steelers were doing a 7 on 7 drill and Dwyer, not practicing because of his shoulder injury, stood with his offensive teammates behind the backfield. Every other offensive player watched the plays develop. Dwyer had his head in the clouds. He tried to engage some teammates in small talk and he actually turned his back on the plays a few times as he low-dee-dowed it. Not a good sign for an injured rookie sixth-round draft choice already on the hot seat. As I watched, I remember something backfield coach Kirby Wilson told me early in camp, that Dwyer has to learn that football is important to him all of the time, not just once in a while.
