Buster and Pinklon are guys who'd have a great chance to beat Usyk just not in the condition they fought Holyfield in. Bowe, Moorer and Lennox will beat him so I guess its Bowe he loses too first. Valuev beats Usyk especially when Usyks really older because its hard to assume Usyk ages as well as Holyfield. Theres his 8 losses penciled in right there with Ibragimov being an interesting 9th one. Old Foreman can beat Usyk but would favor Usyk to win because his chin is fairly strong. I'm not picking Qawi, Tyson or Mercer to beat Usyk but will give them a better chance against Usyk then Holyfield. Holyfield beat Moorer because he had a career night where everything was clicking without that Usyks not beating Moorer. Holyfield was also tough and aged incredibly well something we can't presume to happen with Usyk.
Usyk is nil beating Lewis or a prime Bowe or a prime Holyfield ... no knock on him as he is great and courageous.
He doesn't beat Tyson, He beats Bowe, Moorer, Foreman, Mercer, maybe Lewis but I would favor Lewis to grind it out
Bowe needed a gift against a faded Toney Tubbs, and was in serious trouble against Herbie Hide. He would have no chance at all against Usyk. Sure he beat Holy, but who knows how much HGH was in Evander's system at the time.
