Great posts from Senya13 and Stonehands89. I think they have it about right. MancMexican is right about prime Calzaghe having power though (dropping Eubank within 15 seconds proved that). If you thought Calzaghe was good against Kessler and Lacy; he was even better in his prime. That said, Jones was probably unbeatable at 168 in his prime and I agree he'd beat Calzaghe; probably 8-4. But it would have been a HELL of a fight.
