Johansen gave Colorado a 1-0 lead at 5:19 of the first period, scoring with a one-timer from the left circle off a cross-slot backhand pass from Rantanen on a power play.
"We kept working hard all night, and we just have to keep working hard, practicing and getting our team game better and better," Johansen said.
"We were not perfect, but our confidence is growing as a group."
Clutterbuck tied it 1-1 at 10:03 of the first when he deflected in Dobson's slap shot from the point.
Makar responded to make it 2-1 at 12:52. He skated into the zone, got around Pulock, and roofed a shot over Sorokin with his backhand.
"I liked our first period. We set the pace. It was really good," Bednar said. "They pushed harder in the second, and we didn't handle it well. When we made mistakes, they capitalized."
