Right now I would give him chance only against Haye. Wilder and Joshua are too big and strong. 2-3 years of more experience and I would give him at least 50% against either of them.
He's excellent, but he is not a HW.......yet. With Wilder, Usyk has a chance because despite his height Wilder is a smallish HW (frame wise). Haye is old so I can't call it. Joshua, I'd give Usyk no chance whatsoever.
Wilder and Haye wouldn't take the risk. AJ could be a genuine possibility at some stage, not in the near future tho. Better off asking this question after each has had a handful more fights.
Usyk boxes the ears off Wilder. Szpilka was touching him up—had no answer for those level changes. The Ukrainian hits every angle and then some.
Only Joshua would be a threat to him, and he might win any of them. He has a serious chin and boxing ability.
I think he would be 2-1. AJ his toughest match up. Haye hasn't had a pair for years. Usyk beats him. Wilder is a bottom level top ten talent fighting top 15-50 guys in title defenses. Usyk wins here, via TKO.
Usyk in 2-3 years has great chances against of them. Usyk is so much more skilled than AJ or especially Wilder. But they hit much harder, and are much taller with longer reach. Haye isn't as skilled as Usyk, too. He's comparable in size, but hits much harder. AJ would be the toughest opponent since he's improving, and has all physical advantages. If they met in 2012 or 2013 though, Usyk would dominate Joshua and win every round easily. AJ back then was stiff, lost to few Usyk victims, and was dominated by Savon who I think isn't as good as Usyk.
And right after the fight, you'll claim that you were trolling and wasn't really serious about your prediction. By the way all 3 fighters will massacre Usyk .
I actually think Usyk has a decent chance against all three. He beat the big HWs in the amateurs and the WSB, so size isn't everything.
He beats the current version of Haye easily. Wilder and Joshua would be harder fights but I think he'd at the very least be competitive. I had concerns about his head movement and the lack of it in his last fight but then I saw his fight vs Joe Joyce in WSB and that has convinced me he can be a force at heavyweight when he moves up. He showed a lovely array of skills that were effective against a bigger man in the Joyce fight and showed he could also take a decent punch from a big hitter without headgear. I think he could beat Wilder, he would make him pay for his mistakes but of course Wilder is always dangerous and has a good jab that could give Usyk problems. Joshua right now might be too much. I need to see Usyk in with some heavies before I favour him over Joshua just yet.
