The man had great athletic genes. He was very strong, powerful and above all else durable. I think people often overlook him when discussing the best chins of all time
He indeed had a great chin. That's why his ko loss to Savon in the amateurs perplexes me. I know he was only 18 but i don't understand how he went down like that. Could it have been the headbutt? And yes, he had tremendous muscle mass. But anything over 220 lbs is just extra fat even for a big boned genetically gifted guy like Tua.
