agree wit everythin ur sayin but pac wasnt timmys first fight at 147 . his first fight there was with carlos abregu.
I think the reason people keep saying Bradley can fight at 154 is because he fought at 152 in the amateurs (I think he fought Ward in the amateurs there, not entirely sure about that one though) and reportedly walks around in the low 160s. He's pretty stocky and built. He'd get slaughtered by the guys fighting at 154 now though.
