What is Pacquiao's biggest win?

[shadeyfizzle]

Against chatchai sasakul he became the youngest world champion in boxing history

Against Barrera the coming out performance with the huge upset

Against Hatton in what will be the defining image of his career

Against cotto for the record 7 division championships.

Your thoughts?

[Franco2012]

Barrera for sure,he was p4p number 2 when Pacquiao killed him

[LeG00N]

Barrera .... the Cotto one was up there though

[Bee Keepz]

Cotto for me, that's a huge accomplishment for a former Flyweight.

The way he did it in was a bonus.

barrera.......

[SCtrojansbaby]

****** poll the answer is Barrera and its not even close if you say otherwise you simply do not know anything about boxing

[Pocket Dogs!]

Barrera because he was a top 5 P4P fighter and Pac was just considered a stepping stone in that fight.
