As I see it, Pollard and Deuce are locks for the roster. That leaves:
Ronald Jones
Dowdle
Leupke
You can’t view the RB situation in a vacuum. Roster spots will be at a premium. Ronald Jones is suspended for the first two games. I’m not sure how that affects his necessity to be on the initial 53 man roster. My guess is he still has to be in the 53 or be cut.
If that is the case, then I think it’s pretty clear that Jones gets cut. I think we will want to keep Leupke but I think he will get cut and pass through waivers through to the practice squad.
I think most expect Dowdle to be on the 53 man roster, but I could see a scenario where Pollard and Vaughn being the only two kept initially and added back to the practice squad after they clear waivers.
