The Blues played Monday following the long All-Star break. St. Louis lost to Vancouver, 3-1. The Blues, though, fired 37 shots on net. They entered that matchup having scored 3 or more goals in 12 of their last 13 games. 
The Flames are home, but at a disadvantage. It has been 10 days since Calgary last played. The Flames are sure to be rusty while the Blues are not. St. Louis is 6-1, too, the last seven times when playing without rest. 
The Blues also have defeated the Flames in four of the last five games, including blanking them, 5-0, at home on Nov. 21 when the teams last met.
