Let's be fair to Peyton. He isn't winning 12 games with the team he had in 2005-2006. Marvin Harrison's performance is declining, he had no run game to speak of, his offensive line was banged up and inconsistent, and his defense could still be better against the run.
That team begins and ends with Manning. The beauty of Miami is that they were assembled to where there was no one player that truly had to shoulder an excessive amount of the responsibility. Chad was a huge part of our success, no doubt, to the extent I question whether we'd make the playoffs without him, but I know the Colts wouldn't have a shot in hell with Sorgi at the helm.
