The thing is that Manny has never been a KO artist anyway. The Hatton one was a one off. At the lower weights he stopped people with an accumulation and at the higher weights doesn't really stop people. But how easy is it to win rounds against Manny? It is bloody hard. It doesn't matter if he stops Floyd or not, he will be more active, landing more, and Floyd has been losing quite a few rounds by being outworked in recent fights. I don't think Floyd has the legs to stay off the ropes against Manny for 12 rounds which means that Manny will be in close for some of those rounds and he is fast, unpredictable and hard hitting. Reach matters but only if you can keep it in the middle and that is easier said than done. Mosley tried to box, but you still get outworked every round and it ends up being survival. Same with Barrera. Same with everyone unless you choose to fight and then you get stopped or end up looking like a Chinese sailor. Even in that last Marquez fight, Marquez was starting to lose it and it looked like Marquez was the one that had been worked out.
