I don't think Coker did anything to warrant losing his starting job. If it ain't broke . . .
It's not like Foster's three TD's were really long runs . . . he punched two in from the 1 yard line, and the third was a short but powerful 3 yard TD I believe.
I don't think the RBs care who starts so long as they get their carries. I feel the same way. I could care less who starts, so long as they run it well when they're in the game. You gotta love being able to throw opposing defenses a changeup with the differing styles, and it's great to have fresh legs throughout the game.
