The best don't simply score goals every third chance or so. They're a looming specter that buys time and space during 40-odd minutes of even strength play -- a constant, overhanging threat that forces defenders to hesitate, to keep sticks and elbows to themselves in order to not take the trip to the box that their coach specifically warned them to avoid.
It's been a few years since the NHL has seen a truly frightening power play, but there have been some holy terrors in the past.
