A loss against a bad Chicago team would be disappointing/frustrating, but there is just no such thing as a "must win" NHL game in February when you are 4th place in the league.
In the remaining 19 games, we are probably going to throw away 3 or 4 games that we should absolutely win. So will Dallas and so will Colorado. That's what happens when you play 20 games in 6 weeks.
This isn't directed at you 2 in particular, but is just a thought that was kicking around in my head for a couple weeks when the Blues kept losing. Terms like inexcusable, unacceptable, do-or-die, must-win, etc seem to get thrown around so much when discussing an 82 game regular season. I'd wager that every NHL team in the league has 15+ games that are "unacceptable" and every NHL player makes dozens of "inexcusable" mistakes every year. At what point do fans need to take a step back and realize that these terms are almost always used as complete hyperbole?
