How many ATG heavyweights do you think there have been? Because your criteria of having to beat an undefeated ATG is hard to pull off. There have only ever been your answer to the above question, minus one. "Wins over reigning champions..." Well, you can only ever do this once. Unless your criteria rewards fighters for losing, as that is the only way they can again beat a reigning champion. I think "wins over past, present, and future champions" is a much better barometer.
True and yea there are not so many ATGS who beat other undefeated ATGS but there are few ali foreman frazier ali spinks tyson bowe holyfield
Missing quite a lot of great contenders here.. Folley Quarry x2 Bonavena Ellis Bugner x2 Lyle Young (debatable I know)
Bobby Cziz None of the fighters you mentioned have as many fights (in most cases successful) with former, current, and future world champions as Holyfield.
