People have gotten far too carried away with Usyk for some reason, I respect him greatly as a fighter and he is one of the ATG CW's. But he has only had 3 fights at HW ffs...
Who is Uysk's toughest opponent at Heavyweight? Joshua. Lennox beat Holyfield twice, and relatively comfortable as well, even though the cards were b.s. Apples and Oranges really. Usyk one of the GOAT CW's of all time, Lennox one of the best HW's. But if Usyk fought prime Lennox at HW, he'd probably get KO'd IMO.
Lets see a pic of Usyk and Joshua after the fight and tell me who looks more roughed up. Not taking away anything from Usyk who used his skills, speed and Great discipline to offset the difference in strength and size but it was pretty obvious that he had to tiptoe around Joshuas power. A more courageous big man with sturdier whiskers might just walk him down and KO him. Same way Lennox did Vitali in.
