1. Gassiev will not get stopped. He has a Wach/Froch type chin, pure granite. And although Usyk can punch , he's not a big puncher. No way will Usyk win by KO, I'd be massively shocked. 2. It's bound to be a fairly close fight. Because both fighters are elite, very good fighters. I can't see how anybody can say one will win easily, it's not gonna happen - they are both just far too good for that to happen. Which makes the judging so important.
Usyk by KO is almost impossible, yes. Usyk by TKO is somewhat possible, though. But Usyk by UD should be the case.
