Yes. Gatekeeper, I think the stamina advantage is significant. Joshua can't go 12 active rounds, under pressure. You'd be lucky if he could do 6. As I said earlier, his physique is not designed to carry that 240lbs and he has been as high as 250. That will not change at this stage of his career and his stamina will only continue to suffer as a result. He likes to take rounds off and Usyk should not let him do that. I don't think Usyk is stupid, so that will be interesting. Usyk's footwork is simply sensational, so he is well ahead in that regard and of course this dovetails with his superior agility, engine and intelligence. I also think he has superior defence. Usyk has a unique way of evading punches, and it sometimes looks untidy, but he uses his head, knees and waist to good effect and a lot of the time takes blows to the arms and gloves. Usyk is someone who doesn't seem to mind taking a flurry, rolling with some punches and evading others, if it means that he can let his opponent punch himself out or respond with a counter. People often spoke about Ruiz doing damage at close range, which he did, but Usyk is also very good at close range and can throw to the body and head in 3, 4 or 5 punch spurts. The difference is that Usyk seems more content for these punches to be "scoring punches" as opposed to damaging ones. And I think he will need the latter - but as said, it doesn't take that much to send Joshua's head spinning and for him to do the funny dance.
