My best guess is that at present (ignoring Dunbar's injury) that the depth chart would look like this: Murray Dunbar Randle Tanner I think the first two are roster locks. I think Randle makes the roster because he is a rookie (but not necessarily because he has out played Tanner). I think Randle has a lot of upside, but so far he has not been flashing as much ability as I thought he would up to to this point. It would only be a mild upset if Randle got cut based solely on preseason performance. I think Randle's spotty play makes us carry 4 backs into the season. I don't think they will risk having to play him a lot early in the season .... he is not ready.
