When a son takes after his father, it's common to refer to him as a "chip off the old block." In the case of the Chavez family, that block is solid granite.
Don't get me wrong: I've been as critical of Julio Cesar Chavez Jr. as any boxing writer. I think his father's legendary name has gotten him opportunities he didn't earn and caused judges to gift him decisions he didn't deserve.
But fair is fair, and just like the famous father, Chavez Jr. can take a shot and keep coming forward.
To me, the heart of boxing is to hit without getting hit in return. But that cannot happen all the time. Even Floyd Mayweather gets touched on the jaw every once in a while (and handles it well when it happens).
So the ability to take a punch and recover quickly is a priceless intangible for boxing success.
