Pac is the greatest fighter in world who will now face an opponent who has a loss and a draw in his last 2 fights. This fight is all hype, it's a farce, don't watch it, Shane has been on the slide for years and had his last hurrah against Margarito (whose style was tailor-made for him). A complete mismatch, Pac win is close to meaningless. At least Shane is getting a nice paycheck, I liked him years ago but he's not a top fighter anymore.
Marquez also got up to school Pac, something Floyd never suffered. On your little chart there, you might want to make a few adjustments: Cotto was not 147, Pac forced him to come down to 145 for a 147lb title fight. Margarito was not 154, Pac forced him to come down to 150 for a 154lb title fight, even though Margarito was never the 154lb champion to begin with.
