We know, we know. Dwayne Johnson was a famous wrestler long before he became an actor. But it wasn't his career as "The Rock" that landed him on this particular list. Johnson was a gifted college football star who played for the 1991 National Championship University of Miami team. He went on to play for the Calgary Stampeders in the Canadian Football League, but was cut two months into the 1995 season. This led to his decision to become a professional wrestler. —XFINITY Entertainment Staff (Photo by Ethan Miller/Getty Images)
