Chucho's finest hour, taking the title from Olivares.
The mentioned fights against Cruz and Caraballo.
Loads of other great stuff on youtube against Olivares, Rose, Herrera etc.
I've said this before, but I think Chucho was a better fighter than any of the modern trinity of Mexicans. Certainly in terms of skill. The bantam era spanning from Macias to Castillo/Herrera has become my fast favourite. So, so many very good/great fighters, most of whom are forgotten outside the smallest hardcore boxing circles. I'd love to see the Castillo-Medel fights, if they're out there.
