Sanchez is the first that comes up to my mind then Chavez.. Sanchez had a short but very meaningful career. That's my opinion though. I notice the name Juan Manuel Marquez is not in the list? I consider him one of the best to his contemporaries. He is still in the process of rewriting mexican boxing history and he might turn out to be best who knows. As for Oscar, yeah i see him as mexican but he act and breath now like an american.
