Welker plays in a limited role and doesn't return punts. Watson gets used as a TE/WR extensively when Welker is out.
Not sure what Simmons physical status is. If healthy and ready to play, he gets the nod over Wendell.
If Pryor continues to be physically improved I think he gets a spot and sees limited action, with one of Lockett/Alexander sitting. If Pryor is not improved then he sits and Alexander becomes a 5th LB, with Lockett a 5th S/ST player.
