A prime Fury would dance around Joshua and make him look rubbish. Mind you Fury was at 30 percent when he fought Wilder and he still schooled him.
It's different landing them kind of punches on someone taller, rangier, slicker, quicker and gypsier.
Joshua is even more predictable that Wilder, Fury reads him with ease and avoids most of his attacks. I'm not saying AJ is slow but he is slower than both Wilder and Fury.
He'd probably hit the canvas. That said, even a 39 y/o past prime Povetkin in the twilight of his career still has a very good chin. IIRC it took AJ, who had 10 years of youth on Povetkin, 23lbs in weight, and a 4'' and 7'' reach advantage, about 6 clean unanswered flush power shots to drop Povetkin on his ass for that first KD. I doubt it would take him that many to drop Fury or Donkey on their asses. Granted it would be much harder for AJ to catch Fury with that many clean shots in succession than it was against little old Povekin, whereas against Donkey it would be as easy as landing them on the heavy bag because Donkey's skills are garbage. That said, despite his his lack of height, reach, weight and youth Povetkin is more than capable of sparking out all those giants if he catches them right and I'd certainly back even the version who fought AJ to do so against Donkey.
He's slower and yes more orthodox than Wilder so possibly more predictable. But Joshua doesn't telegraph his punches as badly as Wilder does. He doesn't c.ock the right hand before throwing it as much as Wilder, he doesn't stamp the lead foot before throwing a big right hand either and his right hand is much straighter. When Molina fought Joshua he said one of the big differences between Joshua and Wilder was it was impossible to read what Joshua was going to do, so had no defence against him, while he could see what Wilder was throwing and more easily anticipate and evade his shots. Now of course Fury isn't Molina but I think he will have a harder time reading Joshua's shots, but they are slower and so he'll have more time to react and then roll with them and take the sting off them. I think Joshua will find it harder to land a big flush shot like Wilder did because he's slower and more predictable but I think he can land more often, just not as cleanly because he has better variety and is just a more skilled boxer than Wilder. Joshua will need to to keep chipping away at Fury and hope he grinds him down enough eventually to land that one big shot to turn the fight.
Why do people insist Wilder was unpredictable against Fury? He literally throws a one, two, left hook the whole fight. That's a basic amateur combo, if you know boxing.
I dunno. It's hard to say. Fury's got one of those weird chins that sometimes looks unbreakable and other times looks highly fragile. He was hurt quite badly by Cunningham --I don't mean the knockdown that everyone always brings up but a couple of times after that when Cunningham caught him flush and his legs sagged. He's been hurt by Firtha as well, and I think McDermott buzzed him too. On the other hand Wlad couldn't put a dent in him and Wilder couldn't keep him down. Joshua could definitely put him down, but he might not be able to keep him there. Fury's willpower seems to override any fragilities in his physical makeup it seems. But everyone's human.
