We haven't seen Kabayel really challenged yet, but at least we know he can take a punch well after the Zhang fight. I wonder what Kabayel would do if his plan A doesn't work, because we have seen him approach the last three fights in pretty much the same way and we know Usyk will have a solid plan on how to deal with it. Plus I'm not convinced on Kabayel's stamina and endurance atm, he looked like he was getting pretty tired himself in the Zhang fight, though he was throwing a lot of heavy shots. Usyk has got to be the clear favourite, but I'd still love to see that fight and how it would shake out.
