The weight issued is nullified by Oscar losing most of his recent fights . He is clearly past his best but Pac is in his prime . Plus Oscar will have to kill himself to make 147 . Pac wont so I dont see it as a huge unfair advantage .

Oscar was at a disadvantage when he moved up from superfeather to fight Hopkins at middleweight . Difference was Hopkins was a long reigning champion and top p4p fighter . Oscar as I say is a business man these days and not a boxer at his peak .
