ATG HW: No.1 Ali ; No.2 Louis ; No.3 Usyk ; Can it be like this?

Any Heavyweight boxer competing at a high level in the 70's, 80's and 90's was literally like walking out into an unmarked mine field. For me, Ali's level of competition is unmatched. Foreman having a very successful second career after a 10 year lay off will also likely never be repeated. Holmes was one fight away from matching Marciano's 49-0 record and many feel was robbed of that accolade. Lewis beat every man he ever faced, including several consensus top 10 ATG's and Louis title reign is unmatched. Evander Holyfield's resume is crazy good and he has a similar standing at CW, the Bowe trilogy alone is highly praise worthy against a peak H2H monster.

I also feel that Frazier gets overlooked, particularly given he was the first man to defeat Ali when both were arguably a little past their best for various reasons. Vladimir Klitschko's title reign shouldn't be sniffed at either. Marciano undefeated and, his resume has some serious names on there, regardless of when he fought them: Ezzard Charles x2, Walcott x2, Archie Moore, two of those names arguably the best LHW's ever in an era of small HW's. Usyk just doesn't have the required opposition or the longevity and that ain't his fault as he certainly has the skill and the minerals.
