Wilder will get viciously knocked out. He couldn't even take Fury's punches, Zhang lands a big left and it'll be night night. Hopefully Wilder will retire after this fight, he overachieved in his career and made plenty of good money. No reason to keep fighting unless it's against the journeymen he spent most of his career KO'ing.
I would hope Wilder could take out Zhang Just to hopefully get Wilder vs Joshua But alas El Chino Gigante likely destroys whatever is left of Deontae.
I am going with ZZ in this fight, probably by mid to late rounds TKO. And for the people that keep constantly calling for the retirement of this or that heavyweight if they lose their next fight, I think they should continue fighting, and become a test for the younger heavyweights that's the way it's always been in boxing.
