Now he's trying to get back to the top of the mountain with the Islanders, who lead the best-of-7 Stanley Cup Semifinals heading into Game 2 at the Tampa Bay Lightning on Tuesday (8 p.m. ET; NBCSN, CBC, SN, TVAS).
It's essentially the same Lightning who eliminated the Islanders in the Eastern Conference Final in six games last season.
Trying to figure out a way to inspire the Capitals three seasons ago, Trotz turned to Jamie Clark, who failed to reach the top of Mount Everest twice but accomplished the feat in 1997 and again in 2010. Washington defeated the Vegas Golden Knights in the 2018 Stanley Cup Final in five games to win its first championship.
"I think he failed the first two times, he got farther and farther and he was asked, 'Do you have what it takes to climb Mount Everest?' His response was, 'That's why I'm going back,' and he climbed Mount Everest," Trotz said Monday. "I think that applies to his individual experience, [but] it applies to teams. You're not going to go as far as you think you can and you have to harden, you have to learn from it and then you have to go back and push to get to the next level. I think that applies to a lot of hockey teams as well, and in sport. It's not always going to be the first journey you'll do it and that's it. You sometimes have to have that heartache and understanding of you have to push through. As much as it is physically, it's more of a mental approach in the playoffs."
The Islanders nearly pushed through last season but fell short against the Lightning in a series that featured three one-goal games and ended on an overtime goal by Tampa Bay forward Anthony Cirelli in Game 6.
But following a 2-1 win at the Lightning in Game 1 on Sunday, the Islanders are three victories from their first appearance in the Cup Final since 1984. Teams that take a 2-0 lead are 76-7 (.916) winning a best-of-7 NHL semifinal series.
