Ali Louis Liston Foreman Frazier Larry Holmes Jack Dempsey Jack Johnson There's more. I don't have time right now though.
Lewis, Holyfield and IMO, Vitali have the best chances. But I wouldn't make anyone a strong favourite against Mike.
Ali, Lennox and possibly Louis. And I still wouldn't go against Mike with them lot. People mention size, but where's the skill? Fury has no skill compared to Mike. Fact.
6 foot 5 230 lb guys with polished technique versus 6 foot 7 250 lb guys with poor technique. Tyson would eat everyone alive today. 86 to 89 is rather broad though. Still a little green in 86 and could be outboxed and outlasted to s decision ala prime Holmes. Foreman and Ali are about it maybe peak Bowe and Liston doub it though. Tyson would be too much for Louis and Lewis imo.
Tyson in his prime was able to dominate very talented, huge men .. he shut out Mitch Green, Bonecrusher Smith, crushed Carl Williams, Tyrell Briggs and beat up Tony Tucker, Razor Ruddock, Frankl Bruno, Lou Savarese, Andrew Golota .. Tyson was a complete ass and the author of his own fall but in his prime he was one hell of a rare heavyweight ..
