NFC teams getting stronger won't prevent Pats from getting back to the SB.
Miami hasn't signed anyone that made them better and the Bills still have a QB who signed a big contract and disappeared after a good start.
Houston hasn't signed anyone to make them better as far as I know. Getting their QB back should help, but no guarantees.
Manning isn't guaranteed to get any team to the playoffs, let alone Denver. He hasn't thrown a pass in over a year, will have to adjust to a new offense/team and may be shaky worrying about his neck....
Patriots haven't lost any big name players...Welker is tagged.
BB will upgrade positions as he sees fit, and at a price that will keep the Patriots a contender for the future also.
Step back off the ledge...
