Calzaghe was very fast, a great athlete. Speed and great natural energy and stamina.

I kind of see it like Kirkland. This is a very hard fight to get a read on for me. I think there are a number of different possible scenarios and outcomes.

One, Dirrell builds up a lead early cause of his immense natural gifts but falls apart under the pressure and either drops the decision because of getting swept late or gets stopped. Dirrell has some wow factor about him but I've seen him be clearly bothered by pressure from lesser guys than Froch, whether he holds up mentally under the pressure, whether he can hold up stamina wise is the question, and he may not have the greatest chin.

Or he could build up a lead and hold on late to take a close decision.

Or, and I'm not picking this but I don't think its out of the realm, he could dominate. There's nobody in this tournament with the physical gifts of Dirrell, speed and he can punch at times, he's an explosive guy and he might find Froch hard to miss and could stop him. I know Froch has a good chin but he could be getting tagged repeatedly by fast punches that he doesn't see coming and Dirrell does have some power, he's not Andre Ward.
