Philip Rivers
Many praised Rivers when he played the 2007 AFC Championship Game with a torn ACL. The Chargers clashed with the undefeated Patriots as Rivers refused to back out. It was noble but ultimately it didn’t help his team overcome the odds. Rivers played every snap but the injury affected his productivity (via NESN).

History remembers this game kindly because Rivers showed his grit and heart. But he didn’t play very well as he completed just 19 of 37 passes with zero touchdowns and two interceptions. Maybe a healthy Rivers could have changed the outcome of this game. Unfortunately, the injuries came out of nowhere to ruin their chances.
