Heavyweights are tricky because they have really gotten huge and while there is diminishing return, size does matter , especially in stylistic match ups and if you're actually going to rate men from 188 or so to say 250 all time as heavyweights there should be a P4P and a H to H .. that said , guys that intrigue me .. I'll start w Usyk as he's current ... I feel his rematch performance against a motivated and trained Joshua was exceptional ... in my opinion that Usyk beats any Fury who's bravery and charisma greatly supersede his performances over questionable opposition ... By the time he actually fights Fury his inactivity ( two fights in three years ) and age 37 may bring him down to a sloppy decision loss in an ugly Fury lean/hugathon but no doubt Usky is/was a great fighter. Jack Sharkey always intrigues me. Inconsistent and a basket case, at his best in the mid the later 20's he was brave as hell and a terrific fighter .. speed, skill, chin and condition ... Joe Frazier, today highly underrated , without doubt a top five P4P heavyweight ... very small, sight impaired, what he accomplished as a tiny swarmer was astonishing ... Dempsey ... without talking it to death again he may have had the skill to be a cruiserweight version of a Duran or a Manny Paq but his inactivity post title winning victory leaves too many question marks for me ... More to come ..
