How do you think Povetkin would deal with the height, reach, and punching power disparity he would face against Joshua?
Dillian Whyte, despite his 6'4 listing is actually 6'2, and he didn't have an issue finding Joshua's chin. AJ hasn't fought anyone even close to Povetkin's level, doesn't mean in a few years he can't beat him - but now I think Sasha stops him.
I was actually surprised at how well Joshua was able to parry and evade a lot of what Dillian was throwing. I think Joshua's skill set gets under rated on this board.
I think you need to watch the fight again. Joshua got clipped in the second round after Whyte spent the entire first round on bambi legs. He dropped his guard because he was, and is still, inexperienced. It literally took AJ all of 1.5 seconds to recover, clinch, and nullify Whyte. From then on AJ was alert and completely outclassed Whyte. AJ vs Povektin would be very competitive but there's zero reason to think AJ couldn't clinch and out muscle Povektin anytime he tried to get inside.
