Winnipeg trailed St. Louis after two periods before firing three third period goals to take game one.
“You’ve just got to stick with it, stay positive, knowing you’re doing the right things, getting the chances. You know a lot of plays like those cross-ice plays, even the one that Fetsy (Cole Perfetti) made on the power play. I’m trying to get that off as quickly as possible, near a lot of holes in the goaltenders if you can. It was obviously a great play by Scheif. Just try to get it off quick," said Connor.
Scheifele just wanted to get the puck on his stick and let Connor work his magic.
"Oh it’s amazing. All I want to do is put the puck in his hands and he does some fantastic things. Like I said before, I’m lucky to play with him. He’s absolutely fantastic, he shoots the puck fantastic, he does so many little things fantastic. Like I said a million times, he’s amazing to play with," he said.
