PACMAN wasn't 16 pounds south of Barrera..pacman only moved up 6 pounds and won....unlike Margarito who moved up 7 and loss...there's a reason why the smaller weight classes switch from one division to the next so frequently...it's because that's when the size matter most...

Listen if you put a 220 pounder in the ring with a 236 pounder..no big deal right...but if put a 140 pounder in the ring with a 156 pounder...that's bad..even worse is if you put a 126...in the ring with a 142 pounder....

Not saying PBF will be out weighed by 16pounds if they fight..he's still a much smaller fighter...Tony has even came in the ring as high as 157...
