I think Zhang could knock Fury down. Same argument I've used for AJ: If Wilder can do it, someone with power and actual boxing skill can do it too. This of course depends on which version of Fury shows up too. But eh, I don't think Zhang would have enough to finish him and would probably get outpointed, unless Fury is in really poor shape. Wilder 1 and maybe 3 Fury, Zhang can maybe put down and finish. The Fury from Wilder 2, Whyte and Chisora easily wins.
I would think that if anything would motivate Zhang it would be a chance to fight Fury (or Usyk) for a heavyweight title.
Yeah, he was just calling Fury out, he said that Fury did not have a strong chin and he felt he could knock him out.
Of course Zhang can do it. Washed up cw Cunningham did it, never was featherfist Pajkic did it, Bum ass Firtha came damn close.
