Does Pacman realy have to chase Barrera?

In my opinion, i dont think Manny should chase after Barrera. Let him come to papa (Pacman). Since these belts arent realy a good basis of who's good and who's better, it seems like Pacman turned out to be THE MAN to beat and not Barrera. Barrera just got his rank in the p4p by beating EM. but since Pac beat EM and MAB, logically Pac should be on top of Barrera's rank. Pac's quality of beating an opponent makes him deserving to be on that level than Barrera. though it seemed in the past that MAB had avoided a rematch with Pacman by beating EM, and EM's win over Pac seemed like MAB got it even with Pac, now he's (MAB) left without a choice but to fight Pacman to prove himself. not just because he lost to a guy who beat the guy he beaten, but also Pac is the next WBC mandatory challenger. The only way MAB can keep his career is by going up in weight, and make an excuse like "sorry but i have a scheduled bout in 135lbs." i doubt MAB can beat Pacman in a rematch. even he himself knows that.
