If Calzaghe used his south paw jab then he would win a UD. An old Oscar was winning the fight with Money by using the jab, until he got tired that is. It would be a great fight but for me it would have to come down to what Floyd would do, if floyd tried just to counter, I think he would have a jab in his face every 2 seconds then a flurry of slaps just to nick the round. Floyd is very good with his style but he was very open to Oscar jab and Calzaghe has a faster better one. Now if anyone would like to state their opinion on what floyd would do to avoid the jab and flurries then please do.
