Yeah, but you can't blame Gamboa for that. He has faced very good opposition, if not one of the best of a 10 fight prospect. Stooping to the same level is no really the right way to go about?
At least people will know he is not unbeatable and still has flaws in his game and he can still learn.
Gamboa will have difficulties with disciplined and skilled fighters with good chin in his entire career. Marquez is disciplined, accurate, skilled and has a great chin. He stops Gamboa right now within 7-8 rounds.
