Without reading all the other comments in the thread, my first impression after reading the title is Manny Pacquiao should retire and try not to tarnish his legacy in boxing more.
He already did enough for the sport and I assume that he already made enough money to live comfortably for the rest of his life. He is also a senator.
What is he trying to prove?
Maybe he wants to try or reign in every division in boxing? I don't know, when I watched the news he's saying that it will be his last fight whenever he will having a fight but then again he's still fighting.
Manny isn't getting younger anymore so it would be better if he retire sooner like what the others did and don't wait someone will knock him off the ring as that will what the people remember, his last fight.
