It depends on which Calzaghe shows up and which Jones shows up. Joe usually looks good against guys who are aggressive. Hes rarely been in with a guy like Roy who can counter and use his range well. if Roy lays on the ropes and covers up like hes he will have his hands full, but if he can control the center of the ring he will give Joe problems. Also, who knows Joe may get old overnight himself. I think its a real interesting matchup.
