If we were being critical of Usyk and we have to be if we are trying to debate the best heavyweight champions in history, then he has had only 8 heavyweight fights whilst the others were mainly professional career heavyweights.

Best win would be beating the undefeated Fury (who has not always looked the best when facing opponents, he did not take seriously).

Usyk has had only 5 defences, and his career could end up in a worse state than it is now.
