i think after the mayweather fight, manny will have no where else to go in the sport, after mayweather, manny will have no one else of quality to fight. though it's fun watching him beat up opponents, i don't think HBO will get much of a revenue draw.
let manny make his millions, in his 1 last big fight and then he can return home and assist governing the philippines. i bet he does a good, honest job.
perhaps he will raise sports to a new level in the philippines, i remember bodybuilding in the late '70's was popular but i don't hear much about it anymore, of course i don't buy bodybuilding magazines anymore and still read mine from the '70's, (maybe i should renew my stock).
