neither resume above 135 is all that great imo.
pac has some good wins an bad ones one that stands out is the Bradley win,but officially he lost that fight in the Bradley fight and hatton.
Floyd has some good wins some bad ones as well,ones that stand out with him were hatton and oscar.
difference is floyd has a opportunity here with canelo,sergio and a solid win against guerroro if manny doesn't come back strong i think floyd surpasses him.
manny has a great 135 and below resume but he lost once should've lost 3 times imo.
then he was koed in his early career.
floyd dominated 130 and 135 with one blemish the first castillo fight so it's your decision i pick floyd's dominance with one blemish over pac's dominance with about 6 loses or 7 loses.
