I am trying to remember a season in which Blues fans weren’t at each other on social media about their goaltender. It may be the lockout season, which had the double benefit of being a lockout with no hockey, and also before the advent of most social media sites other than maybe LiveJournal.
There was a controversy between Manny Legace and Chris Mason that Legace’s disintegrating play the season after he was an all-star intensified. There was Chris Mason vs. Ty Conklin for a little while, and then there was the rivalry between Jaroslav Halak and Brian Elliott (with a late touch of Ryan Miller added in just to spice things up).
