Yanni Gourde pushed the lead to 3-0 at 14:15 of the second on the rebound of his shot before Stamkos made it 4-0 at 18:21 with a power-play goal from below the left circle.
"They had about 10 or 11 shots in a row and we hadn't had a shot in 8-10 minutes. I don't know for sure, but it felt that long anyway," Cooper said. "Then Yanni comes off the bench, we get a rush out of it, and he makes a great individual effort to score, and that probably burst their bubble a little bit."
DeBrincat scored to make it 4-1 at 4:50 of the third period, from the high slot off a pass from behind the net by Dominik Kubalik.
"They're a team that punishes you when you make mistakes," Chicago coach Jeremy Colliton said. "We made a few and they scored. They made us suffer, and I thought we created more than enough, especially in the second period. We had a long stretch where we were putting pressure on, but then we're down 1-0. Then they get the 4-on-4 goal, we kind of have a long, hard push, and the third one was tough."
