8. Otto Graham

Sport: Football
Retirement Age (Career): 34 (1946-1955)
During his ten years split between the All America Football Conference and the NFL, the Hall of Fame quarterback made it the championship game every year and was victorious in seven. He's still considered to be Top Five Dead or Alive by many and arguably the greatest winner in pro football history. Otto etched the Cleveland Browns into football mythology during their first decade of existence. His legendary accuracy earned him the nickname, "Automatic Otto." Just imagine how history would've turned out if he stayed a couple more years and was teamed up with Jim Brown? #unreal #videogameshit
