In NE? Would have to disagree there....typo?
I think they all stay on the roster - TB/JG for the full season, Bissett can sit on the PS even if he's active for the first 4 games (6 is the max now) as the backup, so they don't have to keep him on the 53-man. Either way JG is a goner - his quality of play will just dictate what they can get for him, and even then we're probably talking 2nd instead of 3rd, or 2 picks instead of 1.
I don't see them signing a veteran backup, mainly because it would cost real money and that doesn't make sense for a 4-week backup. Why would Hoyer (for example) sign a deal here knowing he's going to get cut in October?
