The responses so far have pretty much been way to extreme imo. Either people think he can never do anything to gain more respect as he's already simply so great and some people are just stupid, and then the haters who add substance to that theory. Of course he doesn't need to gain respect in the sense he doesn't have any, that's complete shit he's had a great career. But I think it COULD hurt him in a sense fighting Roy Jones at this stage. It all depends too much on what Roy(and even Joe as well) have left to give. I really don't like Roy's chances to win myself given his legs, but if he looks good in the ring and Joe still deals with him then that goes a great way to increase his stock imo. I mean it's quite possible Calzaghe could show something to suggest he may have given a prime Roy Jones a close fight, it's also possible that he could win and yet still suggest he wouldn't have stood a chance. And then not to mention the possibility that Roy could turn back the clock enough to pull out the greatest win of his career. It is definetly an extremely interesting fight with signifigance for both guys, it's way to late but the clash of styles is tremendous. Also a pretty good undercard, Zab Judah vs someone and Frankie Figuroa(good fighter) fighting Gavin Rees.
