I didn't mean his achievements, I meant what do you think of his ability at the weight? You answered to some extent there by saying who you think would give him problems, but if you could answer more directly please that would be great. What level is his ability at in your opinion at 135. I disagree that Pacquiao beats him at 135, I strongly disagree that he does anything approaching outboxing him. If he has any chance it's to catch him with a fight changing punch like the right hook he developed in recent years, and then follow it up. I doubt it personally. I doubt Arguello would be timing Duran, more like he'd be offset by his great defence on offense and have heavy artillery finding its mark on him. Just my opinion though, none of this can be proven, so I respect your opinion.
