Well aside from Bika being a power punching crazy man Joe did well.

Calzaghe showed off, he has great handspeed, he has a good left hand and his defense is decent.

He looked like a left handed white Roy Jones Jr.....(that being said Roy would have whupped his ass, try to copy THE MAN and you get blasted just ask James Toney!!!) Joe doesn't have great 1 punch power but it's good enough to do damage.

I think at this point in time Calzaghe would humiliate Mikkel Kessler. The real fight that needs to be made is Kessler-Lacy but until Lacy gets back in the ring Kessler-Calzaghe would be good enough.
