Randy Moss
Moss had one of the most exciting career revivals when he joined the Patriots in 2007. The disillusioned wide receiver fell into a malaise in his final season in Oakland. Injuries affected his playing form and he admitted that he wasn’t in the best place mentally (via The Week).

However, he turned everything around when Bill Belichick brought him to Foxborough. Moss won the Comeback Player of the Year Award after leading the NFL in touchdowns again. He probably should have had a Super Bowl win too but the Giants beat the undefeated Patriots.
