How does Joshua hope to win rounds against Usyk, if he struggled against Povetkin?

Povetkin was old, washed up and exhausted. Those tapping body jabs did not affect Povetkin as much as his poor stamina did in my opinion, caused by old age. Even Price was on the verge of knocking Povetkin out. Povetkin would lose to anybody that can fight at a high intensity for 12 rounds. Povetkin is no longer a 12 round fighter.

AJ could barely land anything on Parker. What makes you think he is going to land all that much on Usyk. Mihai Nistor landed at one of the highest frequency on Usyk in the amateurs. And this is the same Nistor that stopped Joshua in 2 rounds. Nistor has a very aggressive, high intensity style, probably hits just as hard as Joshua and Usyk still managed to eventually figure Nistor out and beat him. I can't see Joshua landing more on Usyk than Nistor did. Nor am I sure if Joshua even hits harder than Nistor.
