For me, the AFC is easy to pick, as I'm taking the Power Ravens over the Rusty Colts and the Super Chargers over the Not Ready Jets.
The NFC is harder for me to pick, as I think the Saints are a better version of the Cardinals, but the lack of momentum might bite the Saints, especially if 99 Warner shows up again. The Cardinals, though, won't stand a chance if the MNF Saints show up and rip that stomped defense to shreds. I think the last few weeks of the regular season woke the Saints up, and will be playing with a chip on their shoulder with almost everyone doubting them. I say the Saints win over the Cardinals, but not by much.
The Vikings have had time to get healthy and rested, especially Favre and Harvin, and looked great against the Giants, but if AP doesn't show up against that Dallas defense, 08 Favre will show up and cost Minnesota the game. On the other hand, Dallas can control the clock with that power running game, but I'm wary of the pressure on Romo and Phillips now that they're in uncharted territory again a very stout Vikings defense. I say Favre gets the Vikings to the NFC Championship.
