"We continued to play the way we started the game in the second," Rinne said. "Another two goals and in the third, we didn't let up, kept going. We didn't give them any life. Defensively and from my standpoint, that was the best game we've played this series.
"I think we knew coming in, trying to close out the series, it's always demanding and difficult to do. I thought we did an amazing job."
Arvidsson made it 5-0 at 2:36 of the third period.
"I think that was our best game from start to finish," Watson said. "Obviously with a little bit of a lead in the third period, it's hard not to sit back a little bit. Right away, from the start of the game until the finish of it, we had a really strong effort.
"That's good for us going forward, to be able to take the last game of this series and carry that into how we want to play in the next one."
The Avalanche's top line of Gabriel Landeskog, Nathan MacKinnon and Mikko Rantanen combined for five shots and was minus-9.
"Good series, tonight was tough," said MacKinnon, who had one shot and was minus-3. "I thought we came out with some jump and then they scored two quick goals and it just deflated us, and they got one early in the second that made it 3-0 and kind of ruined our momentum. Obviously, tonight was pretty bad."
