The Penguins returned from a three-game road trip on Monday night, which saw them pick up a win over the Washington Capitals but they also lost the first two games of the trip to the New York Islanders and Carolina Hurricanes.
"I think we played some good periods of hockey this week. On that trip, I thought we did a lot of good things," Crosby later added. "I don't think this game is a sign of how we've played lately, so it's frustrating.
"When you look at wins and losses, we're not where we want to be, but I think leading up to this, we were doing a lot of good things, so if you're asking about our identity, I think what we showed on that trip and previous to that, was a team that works, that's in the other team's face and that's tough to play against when we're all playing together."
Miro Heiskanen scored two of Dallas' six first-period goals, and the Stars beat the Pittsburgh Penguins 7-1 on Monday night.
