12. Philip Rivers
Rivers’ departure from the LA Chargers didn’t get the same attention as Tom Brady leaving the Patriots, but it was the end of an era in its own right. After 17 seasons, Rivers and the Chargers decided to part ways. Now the 38-year-old will lead the Indianapolis Colts.

They offered him a one-year deal worth a guaranteed $25 million. Some believe that this is a big risk because the Chargers and Rivers were awful last year. But the veteran wants to prove that he has gas left in the tank as he pursues a new challenge.
