10.Lennox Lewis : Defeated every man he went in the ring with, which is not something many boxers can say. Greatest ever british boxer extremely smart in the ring and very powerful.
9.Jack Johnson: The first "Real heavyweight" and extremley talented boxer, he would take opponents all the way just to punish them. If he fought in a more modern era he may have been higher in the list, but he fought many middle weights and light heavyweights.
8.Jack Dempsey: Was one of the most Dominant fighters, amazingly powerful and could knock you out with either Hand!!
7.Larry Holmes: Had probably the best left jab ever in the Heavyweight division.Living in the Shadow of Ali, it was very hard for holmes to make as much of an impact but he did this with an 8 year run as heavyweight champ
6.Joe Frazier: The First person to ever beat ali, fought in the "golden era" of boxing and was one of the best! had one of the best left hooks in boxing history. He had a iron chin, and was part of some of the best ever fights.
5.George Foreman: He not only has one hell of a grill, he had one hell of a punch that knocked down frazier 6 times in one round!! He retired and came back to boxing to become the oldest heavyweight champion of all time at the age of 45 which was 20 years after he lost it to Ali
4.Mike Tyson: The Youngest ever Heavy weight Champion, and the 1st to unify 3 major belts and become the undisputed champion. If Tyson had kept Rooney, he would most probably be #1. The most dominant boxer ever in there prime. He had incredible speed and power, a combination of the two that never been seen and probably never will be. He had the greatest ever left hook. His Opponent feared him so much that they would concentrate on not getting hit rather than winning, its a shame he didn’t keep on the right track.. but nether the less he is still 4th.
3.Rocky Marciano: 49-0, the only heavyweight champion in this list never to lost a fight. His power and stamina were incredible the same goes for his chin. And it looks like his record will never be defeated
2.Muhammad Ali: "The Greatest" well almost, easily the quickest heavyweight of all time, and fought in many of the Greatest ever fights. He dominated at a time with many other great boxers, two others who are in the list. Regaining the Title twice he was an awesome athlete
1.Joe Louis: 25 title defences a record that has never been broken! He was technically gifted as well as having a devastating punch that got him the #1 place in ESPNs Greatest Punchers. Lethal with both arms, this man earns his place in my List!
My List changes all the time, but not many leave the list apart from Lewis and Holyfield or liston enter
