Well, I think it's pretty obvious who is going to win the AFC. The Patriots are the best team in that division. I think the next best team in the AFC is Jacksonville or MAYBE the Steelers.--yes, they lost to the Colts, but the Colts are falling apart (they barely beat Kansas City this week). And the Steelers? I say maybe to them because they couldn't find a way to beat the Jets. What an upset. However, they still have one of the best defenses in the league. I only mention the Colts, Steelers, and Jacksonville because New England will have to beat them in the AFC championship, which may not be a sure win for the Pats (even though I love them).
As for the NFC, that's a little more difficult to call so clearly. Dallas and Green Bay are both 9-1, and I don't think that anyone else poses a threat to them. I pick Dallas to go to the Superbowl from the NFC. Dallas has a more complete running game and maybe a slightly better defense. However, both teams are prone to making errors, which, if either goes to the Superbowl, will cause them to be defeated by the near-perfect Patriots.
Dallas vs. New England in the Superbowl. The Cowboys will keep it close with they're running game, but the Patriots will win, just as they did when they played the Colts (who, in my opinion, outplayed the Patriots, but let them win in the 4th quarter).
