Tom Brady vs. Peyton Manning
Tom Brady and Peyton Manning will face off once again Sunday night, just the latest matchup between two of the top quarterbacks in NFL history. Manning's 2013 season has been perhaps his best yet, a tour de force that could see him breaking all kinds of records, while lately, Brady has looked mortal. The debate over who will be remembered as the better quarterback, however, still rages. Manning's numbers are better, but Brady has him beat in head-to-head matchups and -- perhaps most important -- success in the postseason.
