When Mayweather won a junior welterweight belt from Arturo Gatti in June 2006, he did it in brutal fashion. Gatti barely landed any punches while Mayweather teed off on the slower Gatti at will until Gatti's corner stopped the fight after the sixth round. Scary thing is, it wasn't Mayweather near his best, he said. "I was beating him so bad, I backed off of him," Mayweather said in a stunning statement. This is a guy who goes for blood against sparring partners, so to hear him say he went easy on Gatti was quite surprising. But he insisted that is exactly what he did. "I could have gone all out. I didn't beat him with my A-game," he said. "I said if I don't back off him, I'm going to kill him, and I didn't want a man to die in the ring that night. I thought I was going to kill him, I was beating him so bad. I said in my head, 'You're gonna kill him.' So I backed off on him."
