Early in his recap of the Dallas Stars’ Game 5 victory, Sean Shapiro explains why St. Louis Blues fans hold both arms straight up over their heads just before a power play:
Apparently, this is supposed to mimic a two-pronged electrical plug being inserted into a power outlet. The team, in theory, is plugging in and charging up on the “power” play.
But the Stars pulled the plug on the Blues’ man advantage all night. The Victory Green gang held St. Louis to a measly five shots on eight minutes of PP time, and they generated two high-danger shots while short-handed in the bargain.
