Boston has owned the special teams battle in the series, outscoring St. Louis 7-1 on the power play. If that continues to go the Bruins' way in Game 7, it could be the difference in who wins the Cup.
The Blues, though, haven't lost confidence in their power play, which is 1-for-18. They generated 12 shots on goal in going 0-for-4 in Game 6.
However, St. Louis coach coach Craig Berube said adjustments will be made on the power play, including personnel, for Game 7 and the goal is to get in Rask's face more often, make it difficult for him.
"If we keep fighting there, we're going to get one," Blues center Ryan O'Reilly said. "If we can outcompete their penalty kill we're going to have the opportunities and we've got to put them in."
