I'm also thinking SF and NE. I'd really like to see them battle it out in a high scoring game.
Apart of me is rooting for the Ravens or Falcons since Ray Lewis and Tony Gonzalez trying to make a run for the last chance for a ring (or another ring in Lewis' case). On a side note, it was great to see the emotion from Tony Gonzalez, I couldn't quite believe a player of his quality never got a chance to win a playoff game until now.
