I never said it's a fact that he doesn't do well against southpaws but Zab did put paws on him get a legit kd and Chop Chop hurt him the most out of Mosley. Does that mean every southpaw will give him a tough time? No but it isn't outrageous to believe and a roided up Zab with better footwork, handspeed, combination punching and angles in Manny will have success as well.
"No jab=no chance against Floyd" So I'm assuming you are picking him in a clean sweep then
I've said it time and time again, there is no easy W against Pacman, he is beatable but you have to go through fire to do it. Everyone in here talking "easy work" etc is in for a rude awakening, even my GOAT in Bhop
