OL(9): Bakh, Jenkins, Myers, Runyan, Tom, Nijman, Rhyan, Walker, Jones (PS - Tenuta, Empey, Telfort)
I don't see them cutting Newman because that leaves Rhyan as your top G backup. And they don't tend to like shuffling two spots (i.e. moving Tom) in case of injury. As little as I think of him, we don't have many other options.
Edge(5): Gary, LVN, Smith, Enagbare, Hollins (PS - Cox, Mosby)
You are probably right here though. Cox is probably one of those "oh, no, we are going to lose him to waivers" players that just quietly goes on the PS.
I don't think it is obvious that #2 QB is a weakness. I think Sean has been better than MANY backup QB options available this year. He has been better than any rookie QB we've had in a long time (Rodgers and Love included). I don't see any third options (that we couldn't just stash on the PS) anyway.
