Hart said some extra work with goaltending coach Kim Dillabaugh has helped.
"Just getting back to what I was always doing," he said. "Last year, I made sure that I made the most of every practice we had because we don't get a lot of practice time. That's something Kim has been stressing, something I've been really focusing on, is I'm making the most of every minute in practice."
His teammates said they never doubted the 21-year-old goalie would figure it out.
"There's nothing really to be worried about," Couturier said. "I'm sure he wanted to be better, same for us in front of him. I think collectively we stuck together, and we try to support him as much as we can and be better in front of him. Tonight, we gave up a few chances, and he was there to back us up."
Konecny put the Flyers ahead 2-1 at 1:12 of the third period when he scored on the rebound of a Matt Niskanen shot.
