From the late 1950s through the late 1970s, nearly every man who reigned as the Heavyweight Boxing Champion of the World was a former Olympic gold medalist: Floyd Patterson, Muhammad Ali, Joe Frazier, George Foreman and even Leon Spinks all stood at the top of the Olympic podium.
Some of the top box-office attractions of the past 30 years have also been former Olympic stars. Ray Leonard, Roy Jones Jr., Oscar De La Hoya and Floyd Mayweather Jr. all became famous first through the Olympic tournament.
On today's scene, world-title holders James DeGale, Vasyl Lomachenko, Guillermo Rigondeaux and Anthony Joshua all won Olympic gold, as did pound-for-pound contender Andre Ward.
