The Chicago Blackhawks ended a long power-play drought with not one, but two, goals with the man advantage in their 4-1 triumph over the Detroit Red Wings in Game 5 of their playoff series Saturday night. It was satisfying particularly to point man Duncan Keith. Keith's shot from the point - the Hawks' sixth shot attempt of the series- finally gave the Blackhawks' power play its long-awaited payoff when his slap shot was deflected by Shaw past Howard for a tie-breaking goal with 6:52 left in the second period that ultimately made the difference in the Hawks' 4-1 victory over the Red Wings on Saturday night at the United Center. ''That's what we need,'' Keith said. ''[Shaw] made a nice tip there. But more than that he's in front of the net. It's the screen that we need. It's not rocket science. it's keeping it simple, moving the puck and taking what they give you. We did that tonight. I don't know why we haven't been able to do that before.'' Shaw's goal broke a streak of 13 scoreless power-play opportunities - a spate of futility that was worse than the numbers indicated.
