Up two

Chicago over Detroit
Bengals over the Browns
Houston over Oakland
Colts over Seahawks
Tennessee over Jacksonville
Giants over Chiefs
Ravens over New England (I can't believe I am doing this.. I hope Welker doesn't play)
Washington over Tampa Bay
Buffalo over Miami
Saints over NYJ
Denver over Dallas (when in doubt, choose your favourite team. That's what I always say. But seriously, Champ will take Williams out of it, and Newman will do the same with Marshall. I'll take our chances with Witten, because they wont be able to stop the Bronco run game. And the crowd tips it)
SF over STL
Steelers over Chargers
Vikings over Green Bay (what a game that'll be...)
