The Penguins will return their championship lineup almost nearly intact, which allowed Crosby to join practice with a sense of familiarity. He centered the first line between left wing Chris Kunitz and right wing Conor Sheary.
"It's nice having that luxury of having played together," Crosby said. "For the most part, I think that's the case. So it shouldn't take long to kind of adapt. Playing kind of long into last year, I think that intensity, that desperation that you kind of finish off the season with, hopefully we can kind of carry that on to start the season."
Forward Carl Hagelin, who played for Team Sweden during the World Cup, also returned Tuesday and reunited the "HBK Line" with left wing Phil Kessel and center Nick Bonino.
"A lot of familiar faces," Hagelin said. "It's the same focus as last year, so it's an easy transition. … I'm just excited to be here, be back and to play some games here."
Hagelin and Crosby each said the World Cup afforded them the opportunity to get into game shape earlier than they normally would. However, Crosby said he's looking to manage his condition after playing through the tournament.
"When you're playing a lot of hockey it's more comfortable," Crosby said. "I just have to balance rest and recovery and make sure you're ready to play. From everything I've heard it's been a great [training] camp. Guys look really good. … I think just like everyone else, you want to make sure you're ready."
Before turning their attention to the season, the Penguins will take one last look back at their championship Thursday when they visit President Barack Obama at the White House. Crosby visited the White House after winning the Stanley Cup in 2009 and is looking forward to returning.
"I'm excited," Crosby said. "Having gone there before, just to kind of get some good photographs and get to see all the different rooms and see the Oval Office. So it's fun too, just for the new guys, to see their reaction. I think that will be fun too. So I'm excited to go there."
