Couture couldn't explain his scoring explosion.
"I don't know," Couture said. "A couple breakaways, a couple lucky bounces. Shea Weber doesn't turn many pucks over like that. Take advantage of the opportunities I was given. [Marleau] made a great shot on that one. [Thornton] scored a big goal. Guys were scoring, and I was getting some good chances."
Couture missed 30 games because of injuries early in the 2015-16 season. He had surgery in October to repair a broken right ankle before sustaining a thigh injury and having surgery for internal bleeding in December.
"He was outstanding," Sharks coach Peter DeBoer said. "He's just getting better. Again, I can't [overstate] how traumatic an injury he dealt with in the first half of the year. Everyone saw how much we missed him. To get him back now, he's fresh, obviously. He's feeling, I think, getting back to 100 percent, and we're seeing it, the season he maybe could have had had he been healthy all year. He's an elite player."
Couture scored two goals, including the game-winner, in San Jose's 5-2 victory against Nashville in Game 1, and then had a goal and an assist in the Sharks' 3-2 win in Game 2. He had at least a point in all seven games.
