Yes they did score a lot of goals in one game.
And there's no league mandate. Why is goal scoring up across the board? Did the Oilers miss the meeting? It's a damn good thing they shut out the Flames (well they had a goal taken off the board but that's another subject) because they had every opportunity to extend the lead.
You don’t believe refs call a game based on the score? That a team trailing by two is more likely to get a PP in the 3rd than the team leading by two goals? You don’t think that the league has made it clear that the goal is close games?
And once again your inventing reasons to complain.
