Floyd win this! What the ****? Are you even thinking people!!!? Floyd will power(sucker) punch you with his straight right into oblivion and you won't even be paying attention to it.
I do feel that Manny's left hand has lost some of its luster as he moved up in weight. We have not seen that STRAIGHT left hand that Manny used to to throw in the lower weights in a long time. Mannys right hook on the other hand seems to be the dominant weapon in his Arsenal. Mayweathers straight right hand is out of this world but its not really a KO punch. Its fast and sharp like Hopkins, but not really an extremely hard punch.
