Kessler training :-)

[yoitsdan]

Joe's principal sparring partner is Enzo Maccareneli, he's Cruiserweight

And i bet he is fast as lightning

If you've seen Enzo fight you'd be shocked with his handspeed for a cruiserweight, besides, he also had Bradley Pryce who's a light middle, I doubt they're as quick as Kessler though like you suggest, it's going to be a hell of a battle and it's hard to predict, but I wouldn't factor in Calzaghe's sparring as an aid for Kessler.
