Former Detroit Lions wide receiver Calvin Johnson is only 32 years old, but don't expect him to change his mind about his decision to retire following the 2015 season.
He wrote in a Tuesday piece on the Players' Tribune:
"I can honestly say that I don't miss playing. I love football. But it became difficult to love the game as much when I was in some sort of pain every day. I never talked about it while I was playing because...what good would that do? It wouldn't make me hurt any less.
