What does Manny Pacquiao have to prove Saturday night in Macao versus Oxnard's Brandon Rios?
That he's recovered from the brutal knockout loss to Juan Manuel Marquez he suffered in December.
Of course, that was the fourth fight between the two. Perhaps to help him focus more on the positive than the negative, HBO has provided us with the entire Pacquiaio-Marquez III fight, which ended with a majority decision victory by Pacquiao in November 2011.
Which Pacquiao will show up against Rios? The one above, or the one who got knocked out?
