Mayweather is the MASTER of that defense.
He puts one of his arms to cover his body, uses his other hand and shoulder to block shots.
He's been perfecting that since his youth and he's pretty much unstoppable with his acquired speed.
Mayweather doesn't want to fight Pac right away because there are too many money fights before that happens.
Pac matches up well with Mayweather , but I think Money comes out on top.
Can't wait for it.
