I just don't see Denver taking a RB, as much as a few here want it to happen. Denver has had enormous success with later round RB's, and I don't see why Shanahan would be totally unhappy going into next season with Dayne competing for the starting job. Dayne was a total waste of space in NY, but he was very productive in Denver and I saw nothing that would indicate a lack of confidence from the coaching staff.
Having said that, I didn't see him play too much. I don't know how his blocking and blitz pickup is, and I know he can't catch.
