The St. Louis Blues are an in-between team right now if we are all honest with ourselves. It is not impossible for them to miss the playoffs entirely. It is not impossible for them to get hot and climb the ladder.
However, reality is reality and reality says there are three spots the Blues will probably get. They will most likely be the third team from the Central Division or one of the two Wild Card teams.
With that in mind, there is actually a case to be made for the Blues falling out of a guaranteed divisional spot.
