20. Manny Pacquiao
Fight: Manny Pacquiao vs. Juan Manuel Marquez
Don't look at his face, Manny! Look at his fists! In their classic second meeting, both Pacquaio and Marquez pounded each other for 12 rounds before Pac-Man walked away with the split decision. Come Saturday, we expect more of the same in this boxing trilogy that ranks high among those in the modern era. Yeah, we'll promote Pacquiao-Marquez III and expect no financial return. Unless you feel like throwing dough are way...what up, Bob Arum?
