I wouldn't blame Barrera a bit if he decided to retire. He has had so many fights and rematchs already. He's proven himself time and time again. I don't even like the miserable fucker and I'm sayin this. I was rootin for Marquez to school him, and I feel Marquez did win the fight, but not in spectacular fashion, it was far from a blow out, Barrera dropped him HARD, and Marquez never could return the favor or get back to doing as awesome as he was in that round b4 the knockdown. Does Barrera really need to get himself up for a rematch with Marquez, which if he wins could turn into another trilogy? No, not really. I say if Barrera is to fight again he ought to go for Pacqauoi and try to avenge that loss or retire. Maybe fight Marquez again, but really he has nothing left to prove aside from possibly avenging that Pac man loss.
