Tampa Bay has not had more than one power-play goal in a game since Dec. 20 against the Hurricanes, a stretch of 26 games in which it is 14-for-105 with the extra man; its 13.3 percent efficiency about five points below the league average.

The penalty kill has allowed goals in seven straight games during which it killed 20 of 29 power plays (going 2-of-6 in its past two games) for a 68.9 percent efficiency 13 points below the league average.

No surprise Tampa Bay is in a 2-3-2 stretch.

What is startling is the team used to be top-five in the league in both disciplines. It entered Monday seventh on the power play at 19.8 percent, 13th on the penalty kill at 82.2 percent.

"It's been very frustrating," Boucher said.
