No. Adamantium means that you have never shown to be hurt. Ever. Not a leg wobble or a buckle. GGG and Ruslan both have taken bombs and shown zero ill effects.
At 135 to 140 I think it's largely unknown, I suspect he'd be vulnerable if hit by a power hitter at that weight
Guy's been fighting elite, world-class opposition aince he was 16-17 years old and has only been down twice in supposedly over 400 fights, again against the best in the world, once as a pro which was a flash KD and supposedly once in the AM's. And as a pro, especially recently, hes been fighting noticeably bigger guys who can crack and have skill. Some of that is skill and some his chin. Id say very good at the least.
Loma chin is solid. We just wont know how good it really is till he goes up in weight class. Hes too good.
I think the fixation on chin is overstated. Yes its important but it's even more important to not get hit clean. The best boxers do not tend to get hit flush often. They do not tend to get caught by stuff they didnt see coming. They are making small movements and adjustments even as they are getting hit. Its impossible to say how good Loma's chin is as he doesn't get hit that often with power shots. I'd say his chin is probably decent because we've seen nothing to indicate otherwise. His skin though I think is delicate. He cuts and bruises easily it seems.
Since when did 'stunning' someone start counting as a bad chin? Geez... too much over-analysis here sometimes...
I don't think his chin ranks with the best, but it may be good enough due to his talent. Mayweather was hurt a number of times, but no one beat him.
It was an off balance flash KD, he was off his feet when the punch landed, he wasnt fazed at all, he got up immediately without any signs of being wobbled
