Calzaghe would win hands down against any of the super six now in my opinion. He beat Kessler, would take out Taylor and Dirrell. Andre Ward would be tough because of his speed and power, but i'd give the fight to Joe, and Froch just leaves too many openings all the time, and although Joe probably wouldnt have the power to knock him out, he would be able to keep Froch off him and confuse him with his speed and stay away for the points.
Hatton stopped Mallinagi in 11 a while back, and now as it stands i think Khan will have too much speed and power and will take out Mallinagi inside the first five rounds. Paullie just does not have the power to trouble him, infact this is the kind of fight Amir loves, a fast fighter who cant punch and can make him look good as he demolishes him,
Oscar i think was one of the most accomplished boxers of not just the last ten years but perhaps all time. I think his skills in his prime were top class, and he had a heart and brain to complement those skills. I think De La Hoya was p4p one of the best ever. But just my opinion.
