Hopkins sounds confident.
Calzaghe sounds confident.
I felt this fight could potentially be an ugly mess, but it's also a possibility that it becomes a thriller, with the final rounds being critical.

Calzaghe needs distance, Hopkins needs to be within inches of his opponent.
Both counter well. Both have excellent chins and know precisely how to pace themselves. It will be tactical, but I feel that Joe may just prevail on workrate.
