mayweather lost #1 p4p when he became "inactive" for this year. as for pac, he won against jmm @130 to win another alpha belt and lineal title. he also won vs. d. diaz @135 to get another alpha belt and won a 147-lb superfight w/ dlh during the same time span. that should already be enough for pac to overtake pbf considering the latter's "inactivity". mayweather will probably have to beat pac to get it again considering that pac is lined up to fight hatton next. now, can pbf be re-instated at #2 or 3 which jmm and calzaghe now hold? yes, probably. if this is so, mayweather can even inherit the #1 p4p back if pac loses to hatton.
