It was the first one that had everyone talking. Mantha took a pass from Athanasiou on the left side and faked a shot before returning the puck to Athanasiou back door at the right post for what looked like an open-net goal.
Bobrovsky was leaning to his left but was able to stop and stick out his right leg.
"It just happened. I played the first pass. I thought he would shoot but he goes back," he said. "I just throw what I could. I felt it in my heel. It hit my heel. It was good. You're not going to have those every night. It was needed too."
Athanasiou gave all credit to Bobrovsky.
"What a save. It's either going in there or it's not," Athanasiou said. "It's unfortunate it didn't go in. He's an unbelievable goalie. He made an unbelievable save."
Bobrovsky gave up a goal to Frans Nielsen in the first round of the shootout but stopped the next eight tries. Artemi Panarin tied the shootout in the second round.
It remained that way until Johnson, a defenseman, scored the fourth game-decider of his NHL career, against Jimmy Howard, who made 31 saves, including a penalty shot by Josh Anderson in the first period.
"I was actually just watching all the shooters before me," Johnson said. "Every guy was going in to shoot. [Howard] was challenging a lot so I knew I was going in deking."
