Here's the thing, Margarito was exposed by Williams... but a lot of us already knew what Floyd knew, Margarito is a wide puncher who basically just tries to outwork his opponents and land his shots near the end to take them out. Floyd didn't duck Margarito the same way he's about to not duck Hatton. Just because Williams needed the fight to put his name in the top echelon doesn't mean he just beat the best man out there. Floyd would have done a better job against Margarito because he has DEFENSE, and Williams really has none. Floyd would weather the large output by Williams because Willams doesn't have the power to hurt him. He'd counter him all night long, slip the slaps and touch him up. No knockout cause Mayweather really wouldn't hurt Willaims, but it would be a wide UD. This is a thinking man's game and until someone has the intellectual capacity plus the power to out think AND hurt Floyd, no one is going to beat him.
