"I loved the way our team played tonight, right away, out of the gate, skating, relentless puck pressure, great commitment to our checking game, capitalizing on our chances," Avalanche coach Jared Bednar said. "I thought the top line set the tone again, but our whole team was involved and playing well and skating well."
Cale Makar had a goal and three assists, Mikko Rantanen had a goal and an assist, and Philipp Grubauer made 24 saves for Colorado, the No. 1 seed in the Honda West Division.
The Avalanche hadn't played since May 23, when they completed a four-game sweep of the St. Louis Blues in the first round with a 5-2 win.
"Listen, rest is a weapon, especially this time of year," Landeskog said. "We've played a lot of hockey, and I think the coaches did a good job of managing our rest throughout the week and making sure we were ready to go. We knew they were coming off a seven-game series and had one day of rest coming into altitude, so we wanted to make sure we have a fast start, and we did."
