Former Dallas Cowboys quarterback Troy Aikman is probably one of the most recognizable names on the planet. He was a six time Pro Bowler, three time All-Pro selection, and a former Super Bowl MVP.

Yet, when he retired, just a shell of who he was, in 2001, Aikman was reported to have suffered at least ten concussions in his career.
