8. Joe Frazier
The great, late Joe Frazier was one of the world’s top heavyweights throughout the 1960s and 1970s. He was known for his strength, durability, formidable punching power, and relentless pressure fighting style. An Olympic gold medallist, his professional career was also very successfu. In 1970, he became the undisputed champion. This was his crowning achievement.

Frazier’s rivalry with Muhammad Ali is one of the most famous of all time. He beat Ali in their first match-up in the ‘Fight of the Century.’ But he lost his rematches to his fellow legend. George Foreman was the only other man to beat ‘Smokin’ Joe,’ whose left hook was one of the best in the game. In sum, he was one of the most fierce fighters ever.
