I've never seen a heavyweight more able to get inside an opponent as Tyson, even shot Tyson had no problem getting up close to Lewis, the man could slip a jab blindfolded. Joshua simply doesn't have the skills required to deal with Tyson on the inside, the Usyk fights exposed the lack of framing, posting, etc, what worked against Tyson was being physical with him, tying him up, pushing him back and down, Joshua would end up just trading up close and getting KO'ed like he was vs Ruiz. Joshua would do well to make it beyond 3 rounds, horrible style match up from him.
Prime Tyson slaughters anyone around right now. Joshua wouldn't last 1 round Usyk would get KO'd early also. If Fury is fit and back to somewhere near his best he has the skills to win, but I'd still back Mike considering how often Wilder caught Fury.
