Dallas was outscored 14-4 at 5-on-5 in the series. Until Mavrik Bourque's goal at 16:08 of the second period in Game 6, the Stars hadn't scored 5-on-5 since Game 3 and had gone 209:56 of consecutive game play without a 5-on-5 goal.
"I mean, since I got here, and it's only been two years, the standard here is Stanley Cup or nothing, basically," Bourque said. "That's the standard."
Said Stars defenseman Miro Heiskanen: "I think we have a great team, and we have been close (to the Stanley Cup Final). You're not going to win every year and it's hard to win. We have to learn from this and get better. Obviously, you want to get to the Final and get the Cup, but everybody else wants to do that too. ... We just have to get better."
Injuries compounded the challenge. The Stars were without center Roope Hintz throughout the series, a loss that has rippled through the lineup and limited their ability to generate sustained pressure at even strength.
"(Hintz) is a huge part of our team at both ends of the ice," Heiskanen said. "It would have been nice to have him, but that's how it goes in hockey. I think we still had a chance to win, but we weren't good enough to do that."
Hintz has not skated with the Stars since sustaining a lower-body injury against the Colorado Avalanche on March 6. He had 44 points (15 goals, 29 assists) in 53 games. The 29-year-old has 69 points (27 goals, 42 assists) in 95 career playoff games.
Dallas generated flashes of its offensive identity, but lacked the sustained pressure that defined its success in previous playoff runs.
"I know lots of you are going to go to 5-on-5 scoring, but we didn't defend well enough," Gulutzan said. "The chances we gave up were a lot higher quality than what we were getting with the territory we had. We tried to reset a little bit (in Game 6) with our identity, getting back to being a lot more stingy in our effort, but give them credit. We didn't make them work hard enough for their Grade A's and they've got great players that capitalized. I thought we could have been better defensively in this series."
The setback raises offseason questions for a franchise firmly in its championship window. The Stars remain talented and deep, but the abrupt ending will force introspection about how a team built for playoff hockey came undone so soon.
"Sometimes it takes a few times knocking on the door before you can break through, and we have a really good team, really good group, and we'll keep trying to get better," Duchene said. "It's always tough to swallow and it doesn't matter when you lose. When you have a team that you believe can win, you feel like it's a missed opportunity, but we'll sit on that for a little bit and then pick ourselves up, dust ourselves off, and keep pushing forward."
