With the kind of offensive firepower the Blackhawks send out on the ice each game, scoring isn't much of a concern.

It's the other end of the rink the Hawks have been trying shore up, with Thursday night's effort against the Islanders a prime example of the kind of defensive style they need to play to be successful.

By playing a tight-checking, puck-possession game and clearing the crease of danger, the Hawks skated to a 3-2 overtime victory over the Islanders at Nassau Coliseum. It was the Hawks' fourth consecutive victory on the road and their fifth triumph in their last seven games overall.

Patrick Sharp scored the game-winner 1 minute, 34 seconds into overtime when he knocked in a rebound of a Marian Hossa shot for his second goal of the game. Sharp also added an assist while Hossa had a goal —the 400th of his career — and two assists.
