Marquez feels he won the three fights with Pac, and after last nights dissapointment, why would he feel motivated for a fourth fight and probably thinking to himself "I'm just gunna bust my ass in the gym, woop him again, just to lose by robbery again". I feel he should just leave it be and move on, and leave that last thought on everyones mind that Pac got beat by him and was robbed.
Marquez has Manny's number and is probably mentally in his head now. Pacquiao thinking he has destroyed all these bigger men, but can't shake a 38 year old blown up lightweight? Marquez finally gets the decision in the 4th fight. Pacquiao should avoid Marquez like the plague if he wants to have his $50 million from the Mayweather fight.
No doubt he'd win a fourth fight as well, but that wouldn't be the case since he'd be thinking during the fight "Im gunna get robbed in the end" and that would not make him perform well, which in turn Pac would ACTUALLY win due to that.
I would only be worried about it from the point of view that after all that effort on JMM's part - discouragement might lead to him getting hurt at 38 and I don't think he deserves that. Then again - I can't imagine a JMM/MP fight that doesn't go the distance and it stupidly hard to score.
Same thing I was thinking today bro. I dont think his training would be the same and his heart will not be in it. Theres no motivation for a 4th fight...What the hell for.
