CRANBERRY TOWNSHIP, Pa. -- "The goaltender has to be your best penalty killer," has been stated by every hockey coach ever.
And in the Penguins' case, there might even be truth to the adage.
In their past four games, they've surrendered at least one power-play goal in each, yielding six -- on 15 shots -- in 10 total opportunities over that span. If that seems like a lot, it is. Even for the NHL's 16th-ranked (80.3 percent) penalty-killing unit.
