After reading all the arguments in this thread, let me give my humble opinion.

If Pacquaio will do the same thing he had done during the first round of his first battle with Marquez, he will, in very high probability, TKO Marquez around (or even before) the 8th to 10th round.Pacquaio should carefully study what he did to Marquez during that first round. He should do the same thing again. Throw some quick punches then move backwards, that way MArquez won't be able to counter. I think this will be an easy strategy for Pacquaio.

I'm just concerned with how Pacquiao's speed had declined. Many may not have noticed it but Pacquiao had really slowed down (of course, in comparison with his prior performances).IThough compared to Marquez, Pacquiao is still faster. He can use this advantage to counter MArquez. It's like giving Marquez his own dose. That way, PAcquaio will be known as the one of the best counter punchers.

Pacquaio had done the same thing to BArrera. He gave Barrera the taste of how to be defeated using "the technician way".Now he is known as a tactical fighter.

If PAcquaio performs like what he did to Barrera, he will also win by UD.

I believe MArquez will win over PAcquaio if:
1. Pacquaio will be distracted in his training( which is not happening).
2. PAcquaio gets a pneumonia one week before the fight. I just had a pneunomia and its really debilitating.
3. Pacquaio will seriously break some bones in his hand ( hope it does not happen again during the fight).
4....
5.....

For the fans of marquez, please continue fill up the reasons why Marquez will win over Pacquaio.

by the way, regarding GAME, he is not a pacquiao hater. He just supports all mexican boxers. He still owes me a bet over PAcquaio vs Barrera but I am not demanding it. He goes crazy supporting his fighters......posters beware.... hehehe
