It's a strange one. He has gone very gun shy. I don't remember this happening to any other major fighter, it is the equivalent of the yips in a golfer. Even in the Usyk fights, especially the first one, he was terrified about getting hit with that left, an when it did hit the legs wobbled. I do wonder if he has lost confidence in his chin or just mentally not prepared to risk another KO.
Until he learns to let his hands go again he is going to struggle. Even Joyce I would fancy to wear him down and hurt him. Amazing to think this is the same boxer who had a firefight with Vlad an got up off the canvas to KO him.
