If Tzyu is serious he needs a tune up fight first that is for sure. I don't think he could beat any of the big names at 147. Honestly people what the hell makes you think he could beat Margarito? I doubt he could hurt Margarito, and he damn sure couldn't outwork him to win a decision or try to outbox the bigger, longer reached Margarito, from the outside. Margarito would pound him pretty bad I think.
