Umm, how so? Joshua's chin has been tested by plenty - Wlad, Pov, Whyte... He's never been knocked out. Stopped by a temple shot, yes, but his chin has always been pretty decent... It's a Wilder fanboy myth that ought to have died with the equally ridiculous idea that Wilder was ever a legit contender. There's levels to boxing and Joshua has been typically pretty solid at a good level - Dubois isn't even prime yet, he looks like he'll dominate before too long, but let's not get ahead of ourselves just yet.
It's an interesting fight, 2 of the best finishers in the game when they get a man hurt, plus they've both got that little streak of quit in them. I'll go for a Joshua KO by 6 but if Dubois catches Joshua flush then I wont be surprised to see him counted out with that glazed, dear in the headlights look all over his face.
My point is that Dubios "diving" to AJ due to a deal between Hearn and Warren makes zero sense, and giving AJ a strap is all the excuse Hearn needs for a third Usyk bout "to unify, Fury and AJ can happen after" and we never get the fight.
I was never sold on Dubois. I'm not a fan of AJ but I think Dubois is even worse. 60/40 fight for AJ, I would say. Dubois has a good chance to win if he connects clean and early, though, because of AJ's lack of mental strengh and heart. Nevertheless, I think that the most likely outcome is AJ winning this fight. Not because AJ is a hell of a fighter, but because Dubois is worse than AJ. I've always found Dubois limited and overrated.
