Who would win? Would it be Chris Byrd mark III or would Usyk out manoeuvre & Gassiev the bigger man? Both have great footwork... Could Usyk deal with that jab & avoid the big right?
We have no idea about Usyk at Heavyweight. Literally none. He's not even a big puncher. Wlad's jab >>> Usyk's power punches. Maybe he can move up and have success but that's a big maybe.
I guess we are talking prime Klitschko here? Then Wladimir is too big, strong and skilled for his size. Even if Usyk found a way around the jab, and somehow took Wladimir out of his element, there is still the factor of Manny Steward in the corner of Klitschko. I would back them to make the right adjustments and grind Usyk down in the end. Wladimir Klitschko late KO, or comfortable UD. I also firmly believe Joshua would have been KO’d mid rounds if Klitschko still had Steward in his corner at the time. GOAT boxing trainer.
2000-2014 Wlad would run Usyk over. Too good, too powerful, too quick. He'd be a nightmare for any CW coming up in weight thinking they'd exploit a big, slow, lumbering HW.
