Is Julio Cesar Chavez Jr. a good fighter?
In one sense, the question seems preposterous. He's 43-0 with 30 knockouts at the age of 25. His genetic pedigree, as evidenced by that name, is as good as it gets. He's trained by Freddie Roach, the best in the business - who, as a rule, does not train bad fighters. And, perhaps most pertinent to the big shiny TV fight at hand, he is, for lack of a better comparison, the Justin Bieber of Mexican boxing. The man has fans. There's no denying that.
