To quote NHL.com: ”
The winner of the Philadelphia Flyers–New York Rangers game goes to the playoffs, the loser is eliminated. If the Flyers win, they clinch the #7 seed, the Montreal Canadiens are the #8 seed and the Rangers are eliminated. If the Rangers win, the Canadiens clinch the #7 seed, the Rangers are #8 and the Flyers are eliminated.”
Translated – If the Flyers win, the Habs play Washington in the first round. If the Rangers win, it would be either the Sabres or Devils, who are playing each other, for the Habs.
The Devils would make for an incredibly boring series.
