Question for those CC folks with some better first-hand knowledge of this... What is the explanation for the inconsistency of PPs in the NHL.  Even good teams go on mysterious 0-for-20 streaks and the like.  I assume it has something to do with scouts figuring out the opposition's tactics, and then the coaches having to adapt again.  But on the other hand, the PP is one of the more predictable and controllable parts of the game.  Even at the rec level (my level of playing experience), it has always been my experience that slowing the game down and making the easy passes with the man-advantage leads to lots of scoring.  It seems like the ultimate opportunity for tactics to trump individual skill, or lack thereof. Anyway, I'd love to hear some informed (or even uninformed) opinions on this.
