Manny Pacquiao. He may not be a saint, but he's a big inspiration to all of his countrymen every time he fights and represents the Filipino nation.
I feel in this fight the way I felt in the Cotto/Mosley fight. I don't want either guy to loose as much as want either to win. That being said it will be good and close. Much luck to both fighters. Great to have the fights that fans want to see.
I'm a fan of both, so in a case like this I usually root for the underdog. THis probably means that my allegiance to each fighter will change several times depending on the ebb and flow throughout the fight.
