I've been going a bit back and forth whether it would be a good thing if Usyk bulked up to around 230 and in the end I don't think so. You don't want to go in against such a difficult opponent without having tried out coming in that heavy before. He'd need a tune-up to feel how he manages with that extra muscle, not go not really sure against someone of Joshua's calibre. And I don't think he will, no matter the noises beforehand. He'll try and do what he's done extremely successfully his whole career, but I don't think it will be enough.
lol Usyk by KO would actually be more likely than Usyk by decision due to the likelyhood of corrupt judges and Joshua's suspect chin and stamina
I smell nerves I don't think he can adapt that well like he claims. He hasn't shown that during a fight. He's fought scared at points during all his post Ruiz fights. I see that as regression mentally, should have dealt with pulev within a handfull of rounds. If Usyk can outpoint him and he can't make boxing adjustments he's going to be straight back to walk down use his size advantage, might get tagged coming in. If he does walk right at Usyk, Usyk has to be countering almost straight away, both meeting head on then it's a clinch battle or Usyk dipping in and out.
