It would happen at 168. I don't think fighting at 175 would benefit Calzaghe, I reckon he still comes in the ring same weight, except with the extra work he won't look so sluggish.

This would be the perfect finale for JC, I just hope Pavlik brutally knocks out his two next opponents just to reiterate to Joe tha t he is not too be taken lightly. I'll say it again, if Joe comes in sloppy and unprepared against Pavlik he gets KTFO.
