Jones right cross is gonna play a big part, I see Jones landing that punch with regularity with 1,2's.. Then you will see him incorporate bodywork to slow Calzaghe down then he will get more confidence mid rounds by mixing up an array of punches, come the 10th when he has the fight in the bag he will let his foot off the gas potshotting and cruise to a desicion.

I think Roy will counter fine off the ropes, and dont see Joe's power really troubling Roy, on the contrary I see Roy's power and speed troubling Calzaghe. Calzaghe has fast hands but not 100% conviction behing them.. Roy throws fast and still has some business on them.. I think Roys power+crispness on his punches will be enough to make the difference
