Leon Spinks, Heavyweight, 26-17-3
Gold Medal – 1976 Olympics, Montreal, Canada
Spinks’ most famous two fights were back-to-back brawls with Muhammad Ali. In the first fight, he beat a 36-year-old Ali to win the heavyweight championship. Seven months later he lost to Ali and gave it right back. He was roughly a .500 fighter the rest of his career, but a win over Ali and an Olympic gold medal isn’t a bad list of accomplishments at the end of the day.
