The key for Jarry, who is 2-0-2 with a .907 save percentage in four NHL games this season, will be not trying to do too much to match Murray's early success as a starter.
"You are in a position where you are now the starter and your mindset immediately changes from being Robin to being Batman and that's part of the maturity process," said Mike Buckley, who was hired as Pittsburgh's goaltending development coach Sept. 30, 2013, the same day Murray and Jarry signed their first NHL contracts, and is in his first season as Penguins goaltending coach. "You've got to be authentic to who you are and what makes you successful as a goalie, understand your strengths and weaknesses, and keep playing your game."
The temptation to try to do more is common when a goalie moves up a level or into a bigger role, but the reality is goaltenders can't dictate or control what happens in front of them. Trying to force things rarely works in a position that most often is about letting the puck come to you.
Buckley saw Jarry trying to do more in some of his puck-handling decisions shortly after the Penguins called him up. Murray is good at managing the puck by settling it, reading the forecheck and making the simple choice. Jarry is more likely to try to make a play with the puck, perhaps catching the other team on a line change.
"[Jarry] is a very good puck-handler, and any opportunity he has to play the puck I want him to play it. But it has to be a smart decision and not a forced decision," Buckley said. "That's the thing that comes out right away is I've seen him try to make a couple forced plays, try to do too much. That's been our motto the last few games here is just keeping it simple, right down to the preparation for each game and the drills we are working on, just really simple stuff."
The Penguins aren't worried about Jarry trying to play like Murray, however. As well as the two of them get along off the ice, there are differences in their personalities and how they play on it.
Jarry's masks always feature the characters from "Tom and Jerry" as a play on his name, but his personality runs counter to the frantic cat-chases-mouse kids cartoon and is better reflected in his nickname among the Penguins, Casual Jarry.
He lived up to it after Murray was injured Monday.
