Pacquiao can retire whenever he wants IMO. He has had more of a career than 98% of boxers ever do. What, so Joe Calzaghe can hide in Wales forever come out and beat a never-was and 2 old men, and be like"Ai got Nuttin' left to proove en this spoat". Then retire with everyone saying he was a good fighter?LOL Everything pacquiao has done past 135 has just been extra IMO, he shoulnt even be fighting at that weight, but because hes a great fighter looking for challenges, he fights bigger men. 2 years ago the idea of fighting PBF wouldve been ridiculous to most boxing fans, now were gonna be pissed at him for NOT fighting him?? PBF is the one who needs to prove himself, Pac has took enough hard fights for me.
