Tbh now im not sure why calzaghe doesnt keep fighting on.
Fight Dawson, Froch, Pavlik, hopkins and kessler again, fight roy jones again, roy wouldnt say no to a huge fight at cardiff! All these would be mega fights.
All these fights joes more than capable of winning, and would definently add to his legacy. Its a similar sitution i thought about when mayweather jr suddenly retired. If he fought cotto, margarito, williams, cintron even a fight when junior witter was considered 2nd best at 140. There all fights that add to a fighters legacy. All the legends fought the best and gave pretty much every worthy challenger a shot and even if they lost it would only add memorable moments in there career.
