Well even with a loss I'm still happy this team didn't turn over and die. They put up 31 points on the best defense in the league. They rarely turn the ball over, and you never see NE give up a pick-6. ever. So in my mind NE has a loss but a win in morale.
Close out the season 12-4 and with a bit of luck get the #2 seed if Peyton can have a floppy game.
Or you can play on the side of caution to give yourself a chance.
They gave themselves the final chance on 4th down. They have Tom Brady at QB and their defense is suspect. Nothing wrong with the decision really. If you get it, you still have plenty of time to score. If you punt you get the ball with a lot less time with what would probably be the same field position. There was also no guarantee they'd get the ball back.
This isn't the first time the Patriots have put the game on the line on a crucial late 4th down. It's just how they do things.
