Change may be necessary, but it is not always easy on the psyche of the goaltenders involved.
"I feel like when you play, you get in a groove. You lose, you come back in, you don't have to overthink stuff; you can have a short memory no matter what," said Fleury, the No. 1 with the Vegas Golden Knights, who finished a sweep of the Los Angeles Kings in the Western Conference First Round with a 1-0 win Tuesday. "When both guys can go in, sometimes you can maybe get you thinking a little more about stuff you don't need to."
In 2016, Fleury lost the starting job when he sustained a concussion late in the season. Murray, a rookie, took the job and ran with it all the way through the postseason. Fleury played one game, Game 5 of the Eastern Conference Final, against the Lightning.
Murray was injured warming up prior to Game 1 of the first round against the Columbus Blue Jackets last season. Fleury helped the Penguins defeat the Blue Jackets in five games and the Capitals in seven in the second round. But Fleury gave way to Murray after a 5-1 loss in Game 3 of the Eastern Conference Final against the Ottawa Senators and never returned.
Despite added mental pressure, playoff goalie swaps have worked several times before.
Cam Ward was a 22-year-old rookie when he replaced struggling starter Martin Gerber in Game 2 of the 2006 Eastern Conference Quarterfinals against the Montreal Canadiens; he finished the season by lifting the Stanley Cup and Conn Smythe Trophy as playoff MVP.
Darling replaced Crawford during Game 2 of the 2015 first round against the Nashville Predators and started the next four games, but was pulled in Game 6. Crawford played the rest of the way and helped Chicago win the Cup.
Part of the reason the change can work is because playoff teams usually have two good goaltending options. It's not as if they are turning to an emergency goalie like the situation in Chicago on March 29 when Scott Foster, a 36-year-old accountant, played in relief for the Blackhawks. Starter Anton Forsberg was injured during warmups, and backup Colin Delia was injured during the third period of a 6-2 win against the Winnipeg Jets at United Center.
