Sport (Years Played): Baseball (1947-1956)
As the man who broke the color barrier in what was then America's favorite sport, Robinson was one of the true forefathers of the American Civil Rights Movement. A multi-sport star at UCLA, Robinson was famously chosen by Brooklyn Dodgers GM Branch Rickey because he was "a Negro with guts enough not to fight back." Robinson turned the other cheek for a year (winning the Rookie of the Year in the process), but when the mandate to play nice was lifted, he became one of the most intense competitors the sport has ever known, winning the NL MVP in 1949, and leading the perpetually second place Dodgers to their lone World Series title in 1955. In short, the most badass baseball player of all time.
