pq started fighing at 106 and fought as high as 147 and still won, a difference of 41 lbs. if mayweather can duplicate the same then, i am inclined to believe that mayweather is the best p4p. but until then it is fair only to conclude that pq is the best. mayweather is maybe undefeated but there are also lots of boxers who are. if being undefeated is the real creteria of the title then, valero should be the rightful claiman. his record he too much superior than anypresent claimants.
