Calzaghe v Manfredo isn't about boxing,it's about safely marketing Joe stateside against a household name,making him look good and paving the way for a Hopkins or Taylor mega money fight
The Super Middleweight division is starting to get some face back with Carl Froch barging his way into the equation and Froch is on track to get to Calzaghe first not Kessler.
That is if he wants it but i think he'll retire in around 3 fights time and not fight either of them.
