It's partly because he lost to a physically superior SHW in Wlad, partly because Usyk is an elite cruiser vying for GOAT status having already well surpassed Haye and partly because Usyk destroyed Bellew, who KO'd Haye twice. There may also be ethnic/national bias and AJ is a puncher as was Haye, who has a puncher's mentality and biases (which is also why he picked Wilder to beat Fury, who is like a big Haye).
I don’t pay attention to anything David Haye says. He’s an overrated con artist who bs’ed his way into fights he didn’t deserved, and pulled out of more then a porn star.
Great reply my point was that to be called the best fighter you have to beat best. Anyway Usyk did beat giant heavyweight champ. What a great performance. I was very suprised after Chisora match up.
