Except the fact that if he came forward against Aj he'd be susceptible to quick counters and sharp combinations, things he didnt have to worry about coming forward against technically limited Wilder. But even then Wilder still caught him a couple of times in the rematch Fury's mid-close range game is sloppy. It's clear as day, that would not suffice for the Aj fight. Wilder and Joshua are totally different. Aj has better balance than Wilder, better coordination, better footwork, he's a better mid-close range fighter, he has FAR better, quicker combinations, he can pick his shots better, he's physically stronger, he can throw better uppercuts, he has a better jab and a strong left hook. Jesus the guy even has better head movement and ring IQ and those are Ajs worst traits. All Wilder has over Aj is power, but he has power over everyone else so it doesn't matter. Joshua lost to Ruiz mostly because Ruiz is a short guy with faster hands and better inside skills than him, eerily similar to how a 40 year old Povetkin (shorter fighter with superior inside skills) rocked Aj in round 1 and forced him to fight a smart fight for the most part. Tyson Fury is quite literally the exact opposite of those 2 in terms of style and physical dimensions and if he tried to throw his ring IQ in the trash and press the action against Aj then that would make Ajs chances of winning skyrocket and "chinny heavyweight Joshua" would have a field day with him.
