Well lets not forget the age Pac was when he started i mean he was 16 thats the reason think he could start as low as he did at 106. But weight classes are different then they used to be there alot more of them now. I mean if you want to go off how much weight they moved up in there career then it would be Holyfeild for me he start at 175 and fought guys that were up to 246 and still managed to win the title off him as well. I mean that is a move up of about 69 pounds which i cant think of to many people to do that but i dont hear Evanders name anywear near Alis.
