Personally P4P lists baffle me...Are we judging The proven all around superior Boxer or The one who beats fellow P4P fighters?

I can see him at 4th behind Mayweather/Pac/J.Marquez and Calzaghe.Yeh,I understand Marquez just lost a one point fight but Imo He is much more soundly and technically skilled than Calzaghe as an all around boxer.Regular weigt divisions are win or loss effected but does that negate your all around Skill as a P4P boxer??
