I'm currently just rooting for anyone-but-the-Patriots in the AFC. However, I will be endlessly amused if the Colts are stomped in the second round due to the "resting the starters" philosophy which ended in playoff losses in previous years. That being said, I think San Diego is the most likely to reach the Super Bowl.

As for the NFC, I'd like to see New Orleans make it; Brees is so entertaining to watch. If Favre can hold up, then Minnesota probably has the best shot, but that is a pretty big question mark at the moment.

First round predictions:

Cincinnati at home
Baltimore over NE
Dallas at home (though this may be a bit of a trap game after the big win)
Green Bay over AZ
