PITTSBURGH — It’s easy to get awestruck walking into the Pittsburgh Penguins’ dressing room for the first time.

All those stars. All those glittering resumes. All that talent. Hey, there’s Sidney Crosby. Hey, there’s Evgeni Malkin. Hey, there’s Kris Letang. Coach Mike Sullivan understands it can be a little overwhelming at first.

“When a new player comes to our team, young or old for that matter, I think there’s a little bit of a ‘wow’ factor because some of the players we have,” Sullivan said. “Everybody has so much respect for Crosby and Malkin and Letang and those guys. Over time I think that wears off.”

If the Penguins were going to get where they are now – two wins away from the franchise’s fourth Stanley Cup – it had to. Fast.

Fortunately, Conor Sheary, Matt Murray, Bryan Rust and Tom Kuhnhackl are quick studies. The rookies – all of whom spent much of the season with the team’s American Hockey League affiliate on the other side of the state in Wilkes-Barre/Scranton – have found their footing alongside their high-profile teammates during Pittsburgh’s race through the playoffs and a 2-0 lead over San Jose in the Stanley Cup final. Game 3 is in San Jose on Saturday.

There’s the seemingly unshakeable if impossibly thin 22-year-old Murray, who has for now (and perhaps for good) supplanted Marc-Andre Fleury in net. Murray’s 13 postseason victories are a team record for a rookie and two shy of the NHL mark of 15.

There’s the undersized (5-foot-8) and yet redoubtable 23-year-old Sheary, thrust onto a line with Crosby because of his ability to skate as if he’s worried the ice will melt underneath him if he stops. All he’s done is pump in four goals during the playoffs, including the overtime winner in Game 2 on Thursday night.

There’s the 24-year-old Rust, who has a flair for the dramatic. His six goals over 19 playoff games – compared to five in 55 regular-season games – include a pair in a series closeout win over the New York Rangers in April and the game-winner in Game 7 of the Eastern Conference finals against Tampa Bay.

There’s the responsible Kuhnhackl, an intelligent penalty killer who opts for the smart play instead of the spectacular one.

All four in the midst of their first seasons in the league. All four are uncowed by the moment.

“I think they’ve been thrown into a lot of different scenarios,” Crosby said. “They’re handling it really well and they’re coming up big for us.”

“A lot of us have been together for a long time here, starting in Wilkes and making our way up here,” Murray said. “We’re all pretty close friends and it’s fun to be on this ride with all of them.”
