The addition of Brian Campbell has helped the defense, even though he's an offensive defensemen. Campbell is good with the puck and he can carry the puck into the opponents end during the power play instead of playing dump and chase. Duncan Keith might be the most underrated defenseman in the league. Keith and Brent Seabrook have formed a very nice partnership as linemates. The defense of the most part has played well thus far.
All in all, I'm very pleased with the way the Hawks have played this season. I predicted that they would make the playoffs this year and I'm still standing by it. I'm not going as far as predicting that the Hawks will be playing for the Stanley Cup, but I see the second round in the playoffs as a very viable possibility.
