Ezzard Charles
With a record of 95 wins, 25 losses, and 1 draw, Ezzard Charles wasn’t a boxer you wanted to be up against in the ring. The former World Heavyweight Champion defeated Hall of Fame fighters in three(!) different weight classes.
Carlos Monzón
Argentinian boxer Carlos Monzón easily makes the list. For seven years, he held the Undisputed World Middleweight Championship. Yeah, that’s how impressive he was. 14 times, that’s how many times he defended his title. Moreover, he’s thought as not just one of the best middleweights in history but also as one of the greatest boxers of all time.
