27. Greg Louganis-1984 & 1988 Summer Games
Some claim that Greg Louganis is the greatest diver in history, and it is not hard to see why. He was a force in the Olympic Games during the 1980s. In the 1984 Summer Olympic Games, Greg became the only male diver to win both the springboard and platform gold medals. Louganis put on what many say is two of the greatest performances in Olympic Games history.
He completely dominated the competition, recording a 754.41 in the springboard event with the silver medalist scoring nearly 100 points less. He followed it up with a 710.91 for the platform event, nearly 70 points higher than what the silver medalist finished. Greg did it yet again at the 1988 Summer Games. He actually sustained a concussion during practice and came out to win gold at both events, pretty much making him the greatest to ever do it.
