We may be getting caught up in word play here, but I think that Bioli has to 'expect' every starter on the team to get hurt at every position. That is what quality depth is for, because you 'expect' that several of your starters will miss games.
If Branch goes down, we have a sheer rookie, a really past his prime former #1, or a guy from the Chargers who has yet to be a decent #2. We cannot think that a tight end will cover the WR job either, unless one of our tight ends is going to take all his reps from now on at the WR position.
As to the original thread question, I believe that Stone might make the practice squad, Childress has a chance to make the roster unless we bring in a veteran, and the rest will be cut. Brutal but honest.
