Now that the NFC and AFC championships have been determined, who has more on the line: Ray Lewis or Tony Gonzales?

The Baltimore Ravens will face the New England Patriots for the AFC title, a rematch of last year's conference-championship game. Ray Lewis announced a few weeks ago that he would be retiring after this season. For him, it's either win, or go home losing in his last game.

It's a similar story in the NFC, where the Atlanta Falcons will face the San Francisco 49ers. Falcons tight end Tony Gonzalez, a 16-year veteran, finally won his first playoff game on Sunday. Gonzalez has also hinted at retirement after this season.
