I don't know about clowning NE, but I think Pittsburgh has a good shot. NE is just as flawed as anyone left... But having Brady & Belichick (and playing at home) always make them a tough out.
I'm starting to feel like Atlanta is going to stomp GB, though. No real reason... Could just be because it seems like the public loves GB +4.5.
Also, this could end up being the best crowd in Atlanta sports history for the game (final game of the Georgia Dome, hosting the NFC Championship game against the hottest player in the league at the moment, legitimate shot at a championship), which is saying quite a bit for that town.
