I'm going to start putting it in the GGG territory, Usyk has never been wobbled once in his entire career, the closest he came to being hurt was in round 5-6 of the Gassiev fight where he got caught with a nuke at the end of the round, that punch would have knocked anyone out. He fought hard punching killers such as Glowacki, Briedis, Chisora, Dubois, AJ, Fury, Gassiev, Bellew and he's never been wobbled once. Really is an ATG chin
He's never been knocked down ever at amateur or professional level. Even when does get wobbled a bit he comes back strong.
It's not tested, he doesn't get hit enough for it to be granite worthy. He moves too well. Not about his chin, it's his movement.
Oh it's been tested many a time, Fury hit him with about 5-6 uppercuts that KOed Whyte cold across the 2 fights. THe thing is that Usyk doesn't get caught twice in succession.
Yes it has been tested, dude stop making up ****...You're just a Usyk hater...Salty he's dominating boxing now...Sit down.
Usyk's defense is superior to GGG's. So he hasn't been blasted as many times. But given the amount of times it's been tested, especially against naturally bigger oppents, you'd have to say it's grade A.
