I wouldn't want to pay $50 for it but as the fight gets closer I would hit that damn buy button even though every bone in my body is telling me no.
I would pay to watch Calzaghe anyday, doesn't matter who he's fighting. I'd pay to watch any boxer with an exciting style or something extra that others don't have : J.C, RJJ, Cotto, Hatton, Pacqiauo, Tyson, Haye, Gatti
