Bowness tried to spark the Stars to a three-goal third-period comeback by giving Khudobin a breather and bringing in 21-year-old Jake Oettinger for his NHL debut.
Dallas was better in the third, making fewer mistakes, and Oettinger made five saves, but the Stars weren't dangerous or threatening enough to deny Lehner's fourth shutout of the Stanley Cup Playoffs. He made 24 saves, 12 of them in the third.
"Lehner played a great game when he had to," Bowness said. "We didn't put nearly enough chances against him. We didn't put nearly enough shots against him."
And that brings the Stars back to another familiar problem, one that troubled them throughout the regular season: scoring goals.
The Stars lit up the scoreboard in the first two rounds, with 49 goals in 13 games (3.77 per game) against the Calgary Flames and Colorado Avalanche. They have one goal on 49 shots in two games against the Golden Knights, none on 48 shots in the last 117:24.
They're looking more like the regular-season Stars, who scored 2.58 goals per game, 26th in the NHL.
"I still personally think this is more our style of game," Seguin said. "Game 1, we had a lot of [offensive-zone] time. We controlled most of the play. Tonight, we didn't, and they responded. We're going to have to look at film and do a better job at their blue line, especially. We were trying to make kind of cute plays tonight and weren't getting it in deep like we were the first game."
The Stars can succeed in low-scoring games if they're limiting mistakes, forechecking and winning more face-offs. If they're not, it's going to look like it did in Game 2 more often than not.
"We took charge in the first game, first period, right away, and they ended up on their heels," Dallas forward Mattias Janmark said. "Today, it was a little bit reversed. … They were in charge all game."
