re: Crowell, b brown, or a dixon for the season.

Depends. Technically you're in good shape at running back so even if you were to pick either up, if it's really a timeshare, you're not going to put either in the line up anyways. Fred Jackson will also be back in a few weeks. So if you don't need immediate short term help, and I don't think you do, you might be better off gambling on Crowell's big potential should Tate get hurt... especially since you shouldn't be using any of the two possible pick ups considering what you have. At the same time, since you can't predict injuries, I can see why you'd want to make a move.
