Nope. Sorry. Even the Forrest of old couldn't have done it. Forrest claimed the key to beating speed was the jab. But that isn't how he beat Mosley in either fight. He hit and held constantly, especially in the 2nd fight which is why, save for the lone knockdown the two fights were mostly BORING. Mayweather has the uncanny ability to make opponents fight off gameplan (a-la, De La Hoya and the alleged jab he'd throw all night, Hatton's lack of clinching) and if he attempted to hit Mayweather and then hold he would find himself countered whilst grasping at air and then bombed subsequently with body shots. The way I see it, Williams is the best possible hope in recent years of someone who MIGHT be able to do it, although I think he'd fair moderately better than Corrales did in a losing effort.
