Floyd would never knock out Margarito. There are 2 reasons. 1) Floyd doesnt hit hard. 2) Floyd would be too afraid to go for the KO even if he had the chance. Hell,Floyd could've knocked out lil ass Marquez but refused to go for it.
In the same situation I wouldn't go for the knock out either. I wouldn't have been impressed with Mayweather knocking Marquez either.
