Mayweather has a fairly good reputation against highly rated southpaws including Guerrero, Ortiz and Corley, aside from Judah. But these southpaws are far behind from Pacquiao in terms of speed that these southpaws do not possess. Judah seems like a bad choice as Mayweather's sparring partner because he is far from being a copycat of Pacquiao and he doesn't have the foot and hand speed of Manny. Judah's agility and mobility in the ring would not even measure up to 50 percent of Pacquiao's speed. But Judah is confident he can mimic Pacquiao to give Mayweather enough options to neutralize Pacquiao's speed and power
Actually you don't know wtf you're talking about. He never said anything like that. In fact he said the opposite.
It's not a case of finding someone who's exactly like Manny Pacqauiao in every capacity, speed, power, and style. The simple thing is just getting Mayweather in the ring with a few southpaw's that are world class. Your not going to mimic a Manny Pacqauio. Having elite level southpaw's in training camp is honesty the best thing you can do. It keeps him sharp through training camp and then any other adjustments can be made during the fight.
It's like saying that pac's sparring partners can't mimic mayweather. Judah is a southpaw with speed who can crack that's all may needs.
