Pacman showed us why he's the top guy in boxing this past weekend by beating Shane Mosley. Here's a clip of the 3rd round knockdown.
Floyd Mayweather calls himself the best, but when we look at common opponent's that they've fought (Ricky Hatton, Shane Mosley, Oscar), Manny has beaten them much easier. Of course match up of styles determine the outcome of fights. Floyd has to step up to the plate and take on the "Pacman" to prove who's top dog to the fans.
