Let's face alot of people believe that Jones isn't what he used to be. And even if he hadn't gotten knocked out twice, and lost three of the last four people would still notice the slower footspeed, and the diminished reflexes. However, Jones still has faster hands, and just as quick of feet if not faster than Calzaghe. If Calzaghe tries to box with Jones Jr. I think he loses most of the rounds because Jones' hooks are better, his combinations are cleaner, quicker, and harder, and his cross is more accurate. I see Jones jumping in and out too quick for Calzaghe to counter. When Calzaghe gets Jones on the rope he throws his slapping combinations with are bludgeoning, but Jones can deal with it, and retaliates with his own combinations that overwhelm Calzaghe. Also Jones will go to the body which will take alot out of Calzaghe. Regardless Calzaghe is 35, and I think Jones can definitely still do it.
