The youngest heavyweight champion of all time and despite his amazing career in which he was dominant throughout the late 80s he could have and should have been even better. Still great though and for a few years in his prime he looked unbeatable.
4 Jack Johnson
First black heavyweight he was universally hated by white America. Most of his loses come very late in his career (a few come early) Jack Johnson was dominant for the best part of seven years and even his loss against Willard is questionable as he claims he took a dive. Skeptics however ask why wait till round 26 before taking a dive?

2 Joe Louis
Louis was ranked as the best heavyweight of all time by the International Boxing Research Organization, and was ranked number one on The Ring magazine’s list of the “100 greatest punchers of all time” Louis’ championship reign lasted 140 consecutive months, during which he participated in 26 championship fights (he would probably have fought more if his time in the army did not stop him.)

- Muhammad Ali
Some might put Joe Louis at number one I would not argue with that but I’m putting Ali at number one. This is due to his wins against Sonny Liston, Joe Frazer and his best win of all against George Foreman. Ali carried on fighting past his prime and much too long but at his best he was as quick as any heavyweight that has ever lived, powerful, brave and smart he also had his prime years taken away as he was stripped of being world champion and did not fight for 3 years aged from 25 to 28.
