Listen people keep saying how pacman started at 106 but lest not for get he was 16 years old not a full grown man yet he is about the same size as Mayweather is i mean come on you are much bigger then you were at 16. When Oscar and Mayweather were at 130 they were like in early 20s and that still was not the size they should of been at i think people forget that when they bring up the weight classes and how many people move up look at the age it while show if the weight seems light they were young and that is the reason they were at that weight and nothing more.
