Am I the only one who thinks Julio Cesar Chavez Jr looks like the Karate Kid Ralph Machio?

Now that you mention it, he does kinda look like the Karate Kid, and odds are good he will take advantage of that famous name for as long as he can. He is no different in that respect than Ronald Hearns, Camacho Jr. or Laylia Ali. They were all born with a famous last names, but in the ring, their names are irrelevant. They either come real or they get waxed like the next guy/girl. Time will tell, but usually the children of famous fighters simply don't reach the level of success of their fathers.
