Re: Are we overusing Foster?
In the Long term? - YES, we are overusing him.
In the Short term? - No, not until I see Arian get fully on-track for one game. I want to see 150+ w/ a 40+ yarder i there before I think our running game looks "normal" again. Once that happens, 50/50 it all you want. Until it does, keep feeding him (steak pun inferred).
D.B. - That sounds like a nugget of reality wrapped in a layer of embellished hyperbole.
