The Blues came into their game here Saturday leading the NHL in power-play goals and efficiency. Though they failed to score on three chances Saturday, that's a big change for a team that had to rally to finish 19th in power-play success last season. "The two biggest strengths are, we hunt pucks down, so we're not a one-and-done team," coach Ken Hitchcock explained, "and we're willing to go into all the dirty areas to score. All of our goals have not been pretty, but when you're willing to stay on the hunt and willing to go into the dirty areas, that's how you score on the power play." Following Saturday's 4-3 victory, the Blues had seven power play goals in 16 opportunities, a 43.7 percent success rate. Coming into tonight's game with Minnesota at Scottrade, the Blues are five for nine in power play chances at home. In 2011-12, the Note had 45 man-advantage goals in 270 chances, a 16.7 percent success rate. They were worse on the road, where they clicked 13.9 percent of the time. But they are showing a different side this season: that is, they are showing two different sides.
