Opposite to how the Leafs are an elite team that has had some their trouble finishing this year at 5v5 relative to other top teams, the Avalanche have experienced the worst goaltending of the NHL’s 10-or-so-best clubs. Their five-on-five save-percentage ranks 25th in NHL on the season, and only ranks 23rd if you remove their 4-4-0 October. On the PK, they rank 25th as well.
As you would expect, the Avalanche have been primarily propelled by a truly dynamic offensive game. Unlike the Leafs, finishing at 5v5 hasn’t really been an issue for them all year and they’ve been especially goal-happy in recent weeks.
