I don't wanna really see this fight since Zhang will gas around 6 and will just be a punching bag. But it would be a well deserved payday for Zhang. I rather would like to see Zhang in winable matches such as against Yoka, Whyte, Chisora, Martin or AJ.
Zhang can bang but I have my doubts that he could put a dent in Joyce and even if he does land and hurts him, can he put him away? He had Hrgovic hurt more than once and still couldn't end it and if he can't end it how does he deal with the pace and pressure Joyce applies for every minute of every round. If it goes past 6 rounds then Joyce grinds Zhang down and stops him and that is what I see as most likely. So right now I have to favour the more proven Joyce.
Joyce needs to take out some of the other heavies as I think the main 3 will avoid him while they sort their own affairs out. Zhang, Hyrgovic, Whyte or Hunter etc. Can't go back to scrapping with the Charrs of this world. If he gets Zhang and Hrgovic on his résumé he's a contender for having one of the deepest on the circuit.
