Beristain beating Pac twice (with Marquez) may be an advantage for Oscar. Add to that the fact that he seems to have more advantages than Marquez (reach, power, weight, etc.).But I think Team Pacquiao still has the edge in the battle of the trainers even if Beristain is with Team Hoya... Roach having trained Hoya in the past is an advantage for Team PAC...
