Pac has only had one bad fight. His fight with Marquez was a good fight (nothing unusual about that) and no one said anything about Pac possibly fading after that fight. Im not saying he isnt showing signs of fading because he probaby is. With his style and the wars hes been in theres no doubt its going to start taking its toll sometime. I do think we can see a ressurgance in Pac tho like great champs have been known to do. If he loses to marquez I wouldnt be surprised if he retired. If he wins another controversial decision I wouldnt be suprised if he retired.
