Mayweather beats either of the other two. Here's the reason: He does get hit less than Winky, and he is far smarter than the Mosley who faced Winky. He can nullify Winky's jab with footwork and his right hand is superior to Winky's left cross. I think that Mayweather would have a chance though slim fighting Winky as it is, but at the same weight he would win everytime. Same against Pacquaio who just doesn't have enough defense or skill to box with PBF who would use his jab and cross and pick Pacquaio apart.

Between Manny and Winky I would have to say Winky wins this... He has better timing, and IMO Winky was as fast p4p as Pacqiao in terms of handspeed, and still would be fast enough to control Pacquaio with his jab. If Pacquaio had problems with Morales at times then Winky would be way too difficult for him due to vastly superior defense than anything Manny has faced, and far better timing. Everytime Pacman would try to come in that jab would snap his head back.
