TAMPA, Fla. -- The Penguins' power play can be a weapon with few equals, a strike force capable of altering the course of a game with a breathtaking burst of skill and teamwork.
Of course, it also can be what it was during their 4-3 victory in Washington Sunday.
Which is to say, ineffective at some times, downright invisible at others.
That is why, before the Penguins went onto the ice for a practice at Amalie Arena Wednesday afternoon, Mike Sullivan had members of his power play watch video of their work against the Capitals.
