I’m Max Bultman, and I cover the Detroit Red Wings and all NHL prospects for The Athletic. I’m excited to step in on Red Light for James Mirtle, who’s covering the Eastern Conference final. And suffice to say, he’s seeing firsthand that the supposed collision course between the Colorado Avalanche and Carolina Hurricanes is being tested.It’s a sports-filled holiday weekend in the U.S., but we’ve got so much Canada in today’s newsletter.🇨🇦 On tap:

A new PWHL champion

Memorial Cup begins this weekend

Let’s get into it.Juraj Slafkovský scores on Frederik Andersen. (Jared C.

The Canadiens ultimately won 6-2 in a huge statement from the young Habs.Even with the schedule situation, giving up six goals is eye-opening for the playoffs’ most dominant team through the first two rounds.The good news for Carolina is that the rust should be fully off now. In theory, the between-series rest should benefit the Hurricanes more and more as the series wears on and the physical toll amps up on Montreal.But for a Hurricanes team with a history of fizzling out in the conference final, it’s a frustrating start to the series nonetheless.Vegas’ Jack Eichel.

After our staff picked the Colorado Avalanche by an overwhelming 28-1 margin in the pre-series predictions — with 25 saying it’ll end in either four or five games — it’s the Vegas Golden Knights with the early series lead after a 4-2 win in Game 1.This is still a best-of-seven, so overreacting to one game is never advisable. But I still wanted to ask our writers covering the series what they learned in the opener and if there’s reason to second-guess those predictions.
