"We played well tonight," Tampa Bay coach Jon Cooper said. "It was quite a contrast from the last time we played them. Things went our way, but we felt like we deserved for them to go our way. We didn't give them time and space at all."
MacKinnon scored his 20th goal to cut it to 2-1 at 14:14, but Johnson got a rebound at the top of the crease to make it 3-1 at 16:26.
"[Colorado's top line of MacKinnon-Gabriel Landeskog-Mikko Rantanen] is dominating the League right now, and we had to be really good defensively and try to stay above them," Johnson said. "We had to make sure that whatever chances they got they had to go through us to earn them."
Alex Killorn converted a cross-crease pass from Yanni Gourde to make it 4-1 at 2:00 of the second period.
"I think we made it real easy for them," Grubauer said. "Best team in the League. Best home ice (13-4-0). We didn't live up to the challenge tonight. I don't think there's any positive we could take out of this game."
