20. Philip Rivers
The other veteran quarterback to move during the offseason, Rivers played the past 235 games for the San Diego/Los Angeles Chargers. Now, the six-time Pro Bowler has joined the Indianapolis Colts, where, at the age of 38, he hopes to end his career on a high.
However, many critics called on him to retire after a season where Rivers threw 20 interceptions. His signing is definitely a risk, but most people agree that he is better than Jacoby Brissett. To sum up, this one could go either way. A fresh start could either revive Rivers or expose him.
