its the same when Larios had Pac going backwards in the 2nd or 3rd round "Pac was 1 punch away from being ko'd!!! there is no way he can take Hatton's punches"
Pacquiao getting beat up is certainly a possibility however I doubt it would come in the form of an early stoppage if that's what your implying. In fact, if an early stoppage were to happen I think Cotto would be the one to get stopped.
When Pacman gets hit.. he'll raise is hands in the air to let everyone know that it didnt phase him and continue to land combo's followed by that strait left with blinding speed.
One thing is for sure, wheter pac wins or not, he will feel pain, take a look at jmm vs pacquiao 2 round 8 and you can see jmm hurting pac with body shots
The main reason Oscar de la Hoya could not land is because Pac is ****ing hard to land on. His defense is underrated.
