That punch? There were hundreds of powerpunches landed onto Antonios dome, what were you watching? And yeah, you have a guy like Mosley tearing away at you hundreds of times, something is gonna happen to you eventually.
:nono Take Maidana and Adamek out of there.... Adamek was hurt a couple times by Arreola(dont believe the bull**** shoe excuses hereatsch) and stunned/Slightly hurt by Grant whos not even a factor anymore. Maidana has a solid chin but i wouldnt say one of the best. Ortiz played his cards right it was a matter of time before he kod Maidana... Maidana has alot of hard and decent to solid but not great chin. Oh i forgot about mayweather i think hes proven a decent chin... but he hasnt gotten tagged enough to prove hes got a top tier chin. When he has gotten nailed good hes been a little hurt (corley,Judah) or seriouly hurt (Mosley.
'off balanced' - what does that have to do with chin? Learn something about boxing. Who is your pick, then? Vitali and Toney are definitely up there. Mosley and Margarito too. Proves chin has nothing to do with ethnicity or nationality (as some here claim...). But Oli McCall has the best chin bar none. P4P I'd say it's Toney though, seen as he is not a natural HW but can take any HW punch.
