Peyton Manning – 2013
This was an amazing regular season for Manning because it came against the odds. The Colts reluctantly allowed him to go to Denver because they thought he was past his peak. Most people believed that a debilitating neck injury would slow him down but Manning proved them wrong (via SBNation).
Manning racked up over 5,500 passing yards and threw a ludicrous 55 touchdowns as the Broncos stormed into the playoffs in a season that fans will never forget. Unfortunately, things went wrong for Manning and co. in the Super Bowl. Nonetheless, this was a majestic season and he won his ring with the Broncos two seasons later.
