When Cotto got on his bike and started running from Pac, Pac was very frustrated at not being able to fight his fight - Cotto ran and Pac began to struggle to connect and do the damage he's capable of... Mayweather will be able to run and move, but with much more finesse, ALL NIGHT. If Floyd fights Pac's fight, it's all over for him, but Floyd proves time and time again that he can make the fight his fight and keep it that way. That said, Pac will give Mayweather strong doses of stuff he aint ever seen before. He's quick, has more angles than a compass and his ability to punch no matter his stance is just unheard of. I will be behind Pac, but I just worry it will be 'same old story' as Mayweather puts on a masterful display of defence once again
