Zhang is good but we haven't seen enough of him to say he's a atg . BTW joe Joyce has no defense btw.
In my opinion he would. Notwithstanding the outcome, that was basically Wlad's last great fight. He used a lot of clever tricks that he had never needed to against his previous opponents, and took Joshua to the brink of disaster. Don't underestimate that version of Joshua either. Back then he was hungry and vicious.
