Hopkins is somewhat of a dirty fighter. So the chance of him getting DQ'ed and Calzaghe winning is there. My opinion on the names listed is

Jones- I see Calzaghe being competitive with Jones. But Jones by UD
Pavlik/Taylor- I would make Joe the favored over both
Dawson- I see Chad being to big, to strong and to young for Joe
Johnson- No way this happens. Joe already ducked him 3 times. He would make it 4 if the opportunity presented itself
