If every HW champion from Sullivan through Tyson could fight each other - three fights on their best day, who would win the most fights? The fewest fights? I'm almost certain both the winner and the loser would be big surprises. The usual suspects would be high on the list - Ali, Louis, Marciano etc and low on the list Spinks, Hart etc. I'll bet the winner would be a surprise- someone like Max Baer or Jim Jeffries. Likewise the loser- maybe Patterson, Frazier or Charles. Who would your possible surprise winner or loser be?
Ali at his best beats them all. Too many physical gifts plus as tough as they come. Very hard combination to overcome. If the fights were old school of 20-25 round duration my money would be on Johnson and Jeffries as they would be comfortable with these conditions and had the skills to back up their stamina.
Top of the list is probably Ali, Holmes, and Tyson followed by Wlad (if he can hold as much as he wants), Bowe, and Lewis.
ALI from 66 to 68, haven't seen a heavyweight that beat him. Indeed the greatest Holmes from 78, to 81 probably the best jab in the history of div. And if you have a great jab.... Big George. 70/72 scary punching power, and a mean streak. Iron Mike from 86/89 short quick powerful puncher/ the only thing that makes him not THE G.O.A.T is in my opinion the lack of mental toughness in a war of wills. Typical of the so called Bulley fighter whos's great as long as fight is going their way. But adversity........ Joe Louis, great combination puncher, but slow feet and didn't take a great punch sits him back.Smoking Joe viscous left hook, pressure fighter, And if you couldn't keep him off you. Big Sonny wreaking ball left hook, see Big George. Evender is the greatest CRUISERWEIGHT to ever live. Marciano awesome power in both hands but cut easily, slow feet. the Kleichkoes great size but both have been stopped by very average fighters in their primes. Dempsey, refused or wasn't allowed to fight the best fighters esp the black ones. note just my opinions. And everyone here have one lol.
I think the Larry Holmes would come out on top because I think he's the most complete heavyweight that there is without any real glaring weaknesses. The one with the most losses would probably Leon Spinks who with only * fights wouldn't have enough experience and know how to hold his own.
Holmes was always open on the right side. He always dropped that jab. However his jab was so good his opposition had difficulty getting around it. However against the best opposition they would get around that jab. I rate Holmes highly but I believe ATG with great right hands would get to him. Louis and prime Ali certainly.
