Barrera can retire if he wants

...and maybe he should. He's truly done it all. He's given us everything we could ask from a fighter. Avenging the loss to Pacquiao would be a great way to go out, and it would be a huge fight, but it's not necessary. Barrera beat a better fighter than Pacquaio in Morales. He also beat Naseem Hamed, who while undoubtedly overrated, had the same kind of rep and devestating punch as Pacquaio. If he never fights Pacquaio, he'll still go down as the better fighter. Plenty of great fighters have taken beatings. Let's see if Pacquaio lasts as long as Barrera has. With his predictable style, I would bet he doesn't. Even if Barrera beats him, he'll still never avenge his loss to Junior Jones, and he'll still be ranked below Willie Pep and Salvador Sanchez on the list of great featherweights. He's had a long, great career, he's taken a lot of punishment, and the Morales fight would be a better ending than 99% of all boxers ever have.
