Much as the basis for this assessment is on his performance is on that which he provided in the Tsypko fight, I still think that he has plenty to prove. In taking on Calzaghe, there's no doubt he put his balls on the line in the biggest fight in the division in 10 years. However, his fight against Kessler will bring together three of the four belts, and install the winner as the undisputed champion of the division, in my opinion.

As far as Calzaghe is concerned, this is a win or lose fight, which either way will see Calzaghe finally look for the move to light-heavyweight. And if he wins, big fights could be possible. If he fails to beat Kessler, then surely retirement or a rematch are the only options.
