A big part of why sitting out hasn't been easy for Hagelin is because this is the first time he has done it in three trips to the Stanley Cup Final during the past four seasons.
Since 2012, Hagelin has played more Stanley Cup Playoff games than anyone (108). Prior to this season, he missed three playoff games in his NHL career, because of a suspension in 2012.
"I've never been in this situation before, so it's one of those things, it's a new experience for me and I'm trying to see the positives," Hagelin said. "Whenever you get in there you've got to be ready, so it gives me some time to work on my skating and conditioning and get back there, which is good. If I get in, I'll be ready to go."
Hagelin's skating and conditioning has been a concern for the Penguins because of a lower-body injury he sustained in a game against the Winnipeg Jets on March 10.
Hagelin was in a walking boot for weeks following that injury; he missed the last 16 games of the regular season and the first six games of the playoffs. He came back to play in Games 2-6 against the Washington Capitals in the second round, but the injury caused him to miss Game 7 and Game 1 against the Ottawa Senators in the Eastern Conference Final.
He returned to the lineup in Game 2 largely because Hornqvist was injured in Game 1 and couldn't play. Hagelin played the last six games of the conference final, but with Hornqvist available, Hagelin was a healthy scratch for the first two games against Nashville.
