If he's fighting men that generally outweigh him by 20-30+ lbs it may benefit him if he doesn't lose too much speed. Not everybody can be an Usyk.
Well he was 236 lbs back in his fight with AJ and was significantly outweighed when he faced Joyce and Zhang. If he's done a body recomposition increasing his ratio of muscle to fat it could only be a benefit.
I'm 6'2" and he's an inch or so taller but much broader. He's been talking about how much better his conditioning became after his disastrous loss to Joe Joyce. It has shown in his subsequent bouts. Super nice guy.
