If he fights like the way he did with Judah, patient and moderate, and if he can bring anything else he has learned, i think he has a shot. True, khan beat the hell out of a fighter that gave Mayweather problems who was past his prime. He also beat the guy that beat Mayweather copy Broner the problem. Mayweather is a great fighter but he is not all that. He already lost to castillo and is not really undefeated. He is just lucky. If khan can beat on his face a little i bet he loses his composure and then it is up to Khan to be great or not.
