They're both big and strong, Fury is probably weaker than Joshua overall though.
What do you mean weaker? I would agree that Joshua body has more muscles though.
But body muscles is not the primary in boxing. And Andy Ruiz proved that (and number of other boxer with jelly belly). All you need is speed, strong neck and stamina.
Btw, I'm writing this post while eating Ruiz's favourite snickers bar
I'm sure we'll see a different Wilder in the rematch and I doubt he'll make the same mistakes again.
I'm sure Wilder will be the same. He is not a heavyweight. He is just a cruiserweight that gained pounds and is aimed to "one-punch-KO" strategy. Fury is just more heavy and punches too hard for him.
