That little dude is tough as rock, he won't stop coming at you..But i have a feeling that he will get frustrate when he get his head snaps back and forth..He's one of the best offensive Boxers that i've ever seen, but Floyd can deduct his punches output.
I just don't see any advantages vs Floyd for Manny. The only thing Manny might do better is throw combos that's it.
Don't forget his impeccable power, blazing speed, jesus christ like stamina and a work-rate that could be compared to Noah's when he build the ark of faith.
Pacquiao is something else.
