If I had to vote just 1 it's simple... JCC.

Here's my top 10 Mexican fighters.

1. JCC
2. 'Finito' Lopez
3. Olivares
4. Sanchez
5. Roman
6. Erik
7. Canto
8. Saldivar
9. MAB
10. 'Chiquita' (Vastly overlooked in the All-Times lists)

Honors: JMM, Zaragoza, Zarate, Efren, Pintor, Medina, 'Santa Tokyo', 'Cobrita', Arce, Zurita, Kid Azteca, Rafa, Izzy, Herrera, Montiel, Mijares, Solis, Cazares, "Yaqui", Arizmendi, "Raton", Villasana.

*Depending how JMM, Mijares, Montiel, Rafa & Izzy close out their respective careers I think either one could potentially slip into the top 10.
