When Margarito was 18 years old, I saw him fight Alfred Ankamah. If my memory is correct, Ankamah was 14-0 with 14 KOs at the time. He hit Margarito with a killing punch to liver and Maragarito went down. He should have stayed down, maybe even died, because it was a vicious punch. I was ringside and I saw it. But he got up and stopped Ankamah. That had zero to do with 'loaded' gloves, but a whole lot to do with being tough. Not only physically but mentally.
