The St. Louis Blues won their final game of the 2018-19 regular season against the Vancouver Canucks. Based on the other results the Blues had at the end of the year, that was all they could do to put pressure elsewhere.
The problem was the opponents for their divisional rivals. The Chicago Blackhawks and their porous defense was trying to contain the Nashville Predators.
The Winnipeg Jets were taking on the Arizona Coyotes. The Coyotes were a tougher opponent, but they were already knocked out of the playoffs by the time the final day began.
So, basically it all boiled down to that Nashville game.
