P.A. Parenteau had sent the puck up the ice and it deflected off Nashville defenseman Scott Hannan's stick and Predators forward Craig Smith's left skate on its way to a surprised Duchene, who looked over his shoulder before gathering it in and scoring as both Hannan and Smith pulled up.
Even Duchene expected to hear a whistle for being offside.
When he didn't, "I was shocked," Duchene said. "Even after I shot it, I thought maybe I missed something. Like I said, I didn't see the play. It might have been a good call by the linesman, but from what I heard, it wasn't."
This was one of the few breaks the Avalanche have caught this season.
There's a product we might be hearing more about: kevlar socks and wrist guards.
"It’s a tough call," said Karlsson’s defence partner Marc Methot. "Most of us have never even tried them on before.
"It certainly raises awareness now. I’m going to try them out."
"We have skate guards that defencemen should be wearing and I look around and not many defencemen are wearing them," he said. "Players want to be able to play at a high speed and they think that some of this stuff is cumbersome so they take the risk of not wearing it."
Will NHL players get to participate in the next Olympics?
NHL players have participated in the past four Winter Games, and the league is weighing whether it gets enough return on its overall investment, which requires North American hockey to shut down its season for over two weeks to take part.
"I think it is fair to say that if this can be worked out to everybody’s satisfaction, we’d all like to have NHL players at the Olympics," Bettman said. "I think, most importantly, hockey fans that like and love the Olympics would like to see us get this done, and that’s what we’re going to be focused on."
