and we all know he takes on all comers. Thats some old school sh%t right there. Barrera has fought 70 fights in his amazing career.
Without even consulting Manny's record i would suggest that asian fighters in the Oceania area (Phillipines) fight quite regularly as a pretty good source of income comparable to the living conditions here he is from. Indonesians and islanders often have very similar fight schedules (busy)
And most of those fights are wars! Unless Pac turns into a boxer (which Roach is trying to convert him into), I give Pac 1.5 years at most. I believe even now, he is already shoing signs of being past his peak.
