Two southpaws that will KO Mayweather

The two are : Pacman Martinez Question is how long will it take them to disrupt the so called famous shoulder roll by shoot straight lefts right up thru that guard. There is a lane made for the southpaw. Question is how long will it take them to Crack Mayweather as he leaps in with his left hook ??? I am amazed that he lifts his head everytime and is extremely exposed to the Southpaws right HOOK, time it perfectly and he will fall like Hatton and Williams Both Southpaws have excellent foot work and have been buzy with fights whereas Mayweather has not. Matter of factly he hasn't fought a prime elite fighter in many a year in his weight class. He has ducked Cotto and Margo during the time they were elite. De la hoya was out of his prime. Hatton was too small JMM was WAY to small but Jr. felt he had to cheat in weight, for what??? Name an elite prime fighter in the Welter weight division that he has fought in the past 5 years???? He hasn't shown the balls. Its in his blood to quit, his outward actions shows QUIT,,,Roger QUIT badly on his stool Quitters take their frustrations out on women. I think either Southpaw, Pac or Martinez would KO Jr within 9 rounds more likely 4.
