Who'd win this fight ? Joshua is alot faster and obviously more accomplished. Makhmudov however is big and strong as well as big as Joshua. Makhmudov best win is knocking out Mihai Nistor who is a tough competitor himself. Joshua has faster hands and better combination selection in my opinion. Makhmudov is slower however but has one heck of a punch... a hard hitter. I think it would be a great fight.
I don't see how he keeps Mak at bay and doesn't get clipped and go into panic mode like he did in The Garden against a possibly lesser guy in Ruiz. Joshua is still not a mature hw for me, he is at his physical peak but mentally he's likely still weak. Could be a Wlad Sanders scenario.
I don't like AJ, but AJ would demolish Makhmudov. Makhmudov is fun to watch -- I'm definitely a fan -- but I don't think he's a threat to the top guys at this point.
Joshua, although robotic, is still far less robotic than Makhmudov, the only thing he would potentially have going for him is power, he would get outboxed and stopped at this point
The difference is that Sanders was incredibly quick and Makhmudov is slow as hell. Plus Sanders was much better boxer - just watch how easily he had outboxed Ross Puritty. Tommy Morrison went life and death against much less experienced version of Ross
Makhmudov is strong but did not test himself against a real fighter, realistically speaking Joshua should win this given the experience, but you never know, Makhmudov is dangerous enough to be able to prepare a surprise...
