Saying Mayweather isn't a KO fighter is true and it isn't. It really depends on which version of him you get. Floyd has power, but he outpoints fighters so badly most times he doesn't need to use it. Ask Hatton if that check hook hurt, ask Sharmba Mitchell if that body punch hurt, (if you could) ask Diego Corrales and Arturo Gatti if those punches hurt. Floyd was motivated to hurt Gatti after all the back and forth between them got personal and he took a wide-open opportunity when Hatton didn't keep his guard up. Manny is an awesome offensive fighter, but not so much on the defense. Cotto hit him with a nice 3 punch combo and I imagine someone as fast as Floyd can do at least that and mix in body punching too. As for motivation? Well let's see if Freddie Roach has anything to say about Floyd and his father's shaky relationship. I'm not saying that will happen, but I can see Roach commenting about something that might piss Floyd off. 2 things in my mind are very underrated about Floyd; his chin and his power and I can easily see both of these being brought to the front line.
