Needs to beat more people to go from great to…truly exceptional. I think he has the ability, but not the resume.
He beat Klitschko in 2015. Klitschko was 39, almost 40, (Fury was 27 I think) and Klitschko only had one more fight after that against AJ. In the two years prior to fighting Fury, Klitschko beat 5 men - all over the age of 37. He hadn’t fought anyone under 30 for 10 years previous to Fury, since 2005.
Then we have Seferi, Paineta, Schwartz and Wallin (who I think caused him big problems). Good - but I don’t think that is enough to call him a great.
Wilder - entertaining fights, and he is a powerful puncher, but he isn’t Lennox Lewis. Is that really a test for a top ten heavyweight, once Wilder’s power punch is neutralized?
Dillian Whyte - in my opinion, he was always going to struggle because of his size and style. That fight was no surprise really. He also lost to AJ and an old Povetkin at the end of his career.
Prior to Klitschko there was Chisora, Cunningham, Rogan, Abel, Johnson….
He has done well to become world champion, of course. But has he shown the extent of his ability? I don’t think so - not yet.
If he had wins against AJ, Usyk, Hrgovic, and maybe Joyce…then I think his resume becomes as good as it can be in this era.
