The Blues win with defense. They know if they are going to clinch this first-round series they can't get into a wide open skating match with the Jets. 

The Jets defeated the Blues, 6-3, in Game 3 at St. Louis. That game, though, appears to be an outlier. If you discount that performance, the Jets are averaging 1.2 goals in regulation during the four other games in the series. 

Winnipeg has scored just once in its last nine power play attempts spanning the past three games. The Jets also could be without their fourth-leading goal scorer, Nikolaj Ehlers. He's questionable. 

The Blues are averaging only 2.3 goals in their last three games. St. Louis' calling card is its fifth-ranked defense and goalie Jordan Binnington.
