"We played 55 minutes of really good hockey," Edmonton coach Ken Hitchcock said. "We had a tough go on some of the goals, but we had exactly the start we needed, we had a lot of things, and it just seemed like every opportunity (they scored). There was one opportunity we got beat off the wall, on the fourth goal, which was disappointing, but the rest of the time, we did a lot of things right."
Nugent-Hopkins scored on the power play on a shot from the slot to make it 2-1 at 10:24.
Pettersson scored at 18:48 to make it 3-1, picking the left corner from the left face-off circle.
"It's easy to start after the (Christmas) break and have a slow start, so we talked about coming out hard, play simple and just skate a lot and make it hard for them, and I think we did," Pettersson said. "The first period was really good, the second wasn't that good, the first 10 in the third wasn't that good, but I think we finished it really well."
Roussel gave Vancouver a 4-1 lead with 11 seconds left in the first with a quick shot from the bottom of the right circle.
