Anyone who knows anything about sports knows Jackie Robinson. Not only was he a Hall of Famer merely for his bravery in breaking baseball's color barrier, but he was a damn good player too, winning Rookie of the Year in 1947 and MVP in 1949, as well as making six All-Star teams in his 10-year MLB career. These achievements have overshadowed those of his older brother Mack, who was a remarkable athlete in his own right. Eleven years before his little brother would break the color barrier, Mack headed to Berlin for the Olympics as a 200-meter sprinter on the US team. He ended up winning a silver medal, losing by just 0.4 seconds to a guy named Jesse Owens.
