I don't believe Gatti was, sure he may get hurt at times and knocked down but he kept fighting. Amir Khan, that's a bad chin..
In the words of the Great Carlos Zarate.....That was not a fight NC's I dont count. I do think you have treated Tommy harshly. The Grant fight finished due to Tommy injuring his ankle, not due to anything Grant did.
It felt like a TKO1 but it was NC a fight, the standard I used for all This list helps educate people on chins, it depends on stats which I can't change. The cold nature of stats leaves room for spirituality, excuses, feelings, emotions, bias & subjectivity
You have Vitali as a C Class Chin and he was never knocked down and his 2 "KO losses" were do to an injury and a cut. That has nothing to do with the Chin. There are other examples where you are counting "KO losses" when the person was in fact not even KOed. You need to account for that and adjust it.
Tyson Psych ops was so good that his fans (including myself ) can get over the indomitable image super imposed on us His owners always had the perfect excuse: Douglas Busted that Chin (tokyo, the girl, untrained, Just not Tyson) Cruiser Holy stopped him (1st holy head) Cruiser Holy makes him quit (2nd want dont count by stats a DQ) LL busted that chin (Tyson was 36 very old, Tyson 86 was prime) Danny Williams did that chin again (Tyson knee he old 38 man) Mcbride stopped him (Tyson is done man he 39) Roy Jones didn't get the benefit of those excuses, because he was hated for ducking Tiger M & he was not satisfying the peasants with what they want (Tyson grabbing himself & threatening men to do them till they love him) :think
3.78% KO loss ratio for Jake LaMotta by the official* record, could have had a higher score if he lost less, assuming the famous rumors were true
