Only got 2 healthy RBs--Foster and Ogbonnaya. Ward out, Tate hurt, Slaton cut. If you're talking about the actual play-calling and going to Foster, I dont know. I dont think so.
The only thing that looks off about Arian is how he's not finishing every single run, sometimes he just kind of gives up and avoids contact by going to the ground. That will return in time. Gotta get used to getting hit.
