And as long as we have BB as the coach and Robert Kraft owning the team, I think we're in good hands.
As for how much longer Tom can do this? 2/3 years I'd say. You never know though. He keeps himself in great shape and still loves the game and plays with a huge chip on his shoulder. His game has never been a "chuck it 50 yards down the field" type game and with the way they protect QBs now who's to say he can't dink and dunk for another 8 years?
