Pacquiao's Edge

i think the fact he doesn't have to boil down to make weight is one of the keys for his excellence. it must give him confidence knowing he isnt taking anything away from his body. while his opponents on the other hand are starving themselves to make weight. making weight is difficult and can bring stresses on body and mind, paquiao avoids this and in my opinion this helps give him and edge over his opponents. he will know hes at his strongest while his opponents may have may have taken something away from themselves. i think roach said a while ago that going down in weight is way overatted or something like that. does anyone thing paquiao could be setting a trend for how fighters will prepare themselves in the future?
