The Blues and Jets have never met in the Stanley Cup Playoffs. They have met together in the regular season a lot - 35 times to be exact (including the Thrashers). The Jets have taken 18 games, while the Blues have won 17. The Jets have averaged almost three goals a game, the Blues have averaged 2.5.
Literally zip of that matters. That’s the fun of a new season, a new coach, a new team, and the playoffs. Every year is a refresh, and for the Blues this season they got a mid-season reboot after they concluded their four game series.
