Philip Rivers
Rivers was one of the longest-tenured quarterbacks of his generation. Most analysts agree that he was a tier below the likes of Tom Brady and Drew Brees. But he was a loyal servant to the Chargers and a tough individual. His gutsiest performance came against the Patriots in the 2007 AFC Championship Game.

The quarterback had a torn ACL and nobody expected him to play. But he didn’t care and showed unbelievable toughness on the day. In the end, New England won the game but Rivers didn’t let anybody down. He also set a new standard because he showed what people are capable of if they put their minds something (via NFL.com).
