Does Manny Pacquiao fights like a Mexican?

Yup. In a sense Pacquiao has the similar boxing techniques adopted by many Mexican boxer. I travel to Mexico a lot, and many people love Manny Pacquiao there even more than Juan Manuel Marquez. Julio Cesar Chavez is of course their idol and Pacquiao sort of have his style a bit, and as you said also a resemblance of Erik Morales when he throws his combo punches in perfect accuracy. I respect Erik Morales and Julion Cesar Chavez (I have no respect for arrogant and jealous JMM), and i think both had an influential impact on the development of Pacquiao since Pacquiao said Duran and Chavez are his favorite fighters, both Hispanics.
