It can't be, at least in comparison to other HWs. He and Louis should be undisputed options for number 1 and number 2 resumes in HW history. Nobody is even close to them.
I think Lewis resume is slightly overrated, but he still has excellent case for the 3rd best HW ever. Same with Foreman, whose 2nd career is extremely impressive but he doesn't have a lot of top tier wins. Frazier's resume is extremely underrated, as most people view him as career defining win with little else. Same thing applies to Max Schmeling, though with extra anti-30s bias.
Joe Louis resume is underrated: Primo Carnera Max Bear Max Schmeling Jack Sharkey James J. Bradock Jersey Joe Walcott (x2) Billy Conn (x2) All world champions in the boxing era of one HW champion/belt + Billy Conn LHW champion.
In breaking news just about every great heavyweight ever's resume is overrated.......but Tyson no doubt.
calling Alis Resume overrated=Tyson fan lol and i didnt name 2 Best resumes in HW history Louis Holyfield
