Yep, Dirrell is up right now, but I think Froch will decapitate him late. Can't see the judges having Dirrell 3-0 up mind. Rightly or wrongly.
4-0 Dirrell Dirrell is countering beautifully, in addition to the left leads. Froch is routinely leading with the hook and whiffing, but he is landing occasionally to the body. I can see why some scoring more on aggression could lean to Froch, but I think the defense and cleaner punching of Dirrell carries the round.
