Floyd has taken some good shots in his day. Jesus Chavez, Diego Corrales, and Jose Luis Castillo all landed some good shots on Floyd. (the Zab KD was a short, weak hook that Floyd walked into and knocked him off balance.) Those Mosley shots were pretty big. The second right hand could not have landed any better. Floyd wobbled, but really took the shot well. Floyd has been stunned in the past, but he has never seemed seriously hurt other than the big shot from Mosley. I would say definitely not on the glass jaw, but not one of the best in boxing. (Also, I'd like to see Rico convince ANY of the ringsiders for Margarito vs. Cotto and Mosley vs. Margarito that Margarito's chin isn't one of the best in boxing.)
I think he might be retired. I saw him in dallas for the pac-margarito fight and he said he might be done fighting. But yea he got a good chin.
fighters with good chins can get sparked just like anyone else, especially if you rely on that chin as defense without head movement or footwork. but briggs, penelosa, vitali, froch, and toney would get my vote.
What a freaking beast of nature, he was obviously hurt and after the break, had already all his senses back...
