A week into the Stanley Cup playoffs, a few trends stand out. One is that we're seeing a lot of goals. After a high-scoring regular season in which teams averaged 3.14 goals per game apiece — the most since 1995-96 — it's up to 3.27 so far in the playoffs.

Another pattern is that just about every series is close. Yesterday's games ended with four series being tied 2-2, and three more could be even after tonight. The only outlier is the Colorado-Nashville series, where the Cup-favourite Avalanche can complete a sweep tonight after winning the first three games by a combined score of 16-6.

It's not just a vibe: the average margin of victory in the 28 playoff games so far is about 3.3 goals. Six of the eight series have an average victory margin of more than three goals — including a whopping 4.25 in the Edmonton-L.A. matchup, which is somehow tied 2-2. The only series consistently producing close contests is Calgary vs. Dallas, which the Stars lead 2-1 after rebounding from a 1-0 loss in the opener to win the next two games by two goals each — both capped by an empty-netter.
