I know this won't be popular prediction...but I don't think Hamlin and Roy stay....as their position is the weak link on this team. Dallas will have a to make a decision on to keep Roy or Hamlin (both can play SS). I will not rule out the release or trade of Williams...Dallas will take the salary cap hit if it improves the team.
Flo will command too much money. Dallas will move Free to LT and if he can't handle it....they will move Davis over there and let McQ start at guard.
Crayton will be resigned and probably draft a WR in draft.
J. Jones is a gone. Barber will be resigned.
Canty will be resigned.
Players I think will be released or traded:
Roy Williams
Bobby Carpenter
Miles Austin
Tyson Thompson
Terry Glenn
Marcus Spears
Remi Ayodele
Evan Oglesby
