You know nothing, honestly watch him in his prime. He had 362 fights and lost 21 of them.

He beat Golota, Mercer, Briggs, Kirk Johnson, David Tua(one punch KO, he was 24), Brewster, Krasniqi, Solis, Chagaev, Ibragimov, Michael Benett. ALl in all he was a great heavyweight who would have rocked a lot of the best heavyweights in the 90's.
