Here are 3 keys to Game 5:
1. Golden Knights changes
Among them: Tomas Hertl will move up to the top line with Jack Eichel and Jonathan Marchessault, and Dorofeyev will play with Chandler Stephenson and Mark Stone.
Hertl and Stone each scored on the power play in Game 1 but neither has had a point since. Hertl was recovering from knee surgery when he was acquired in a trade with the San Jose Sharks on March 8 and has played only 10 games (regular season and playoffs) for Vegas. Stone missed the last 26 regular-season games with a lacerated spleen.
“Mark’s been through a serious ordeal,” Cassidy said. “So for him, I think it’s about his teammates got to sort of pull him into it here a little bit till he gets his legs under him, right? He’s missed a lot of time.”
2. Dallas defense
The Stars essentially played five defensemen the past two games with Jani Hakanpää out with a lower-body injury. Nils Lundkvist played 2:21 in Game 3 and 1:09 in Game 4.
Vegas wants to take advantage.
“They’re hiding one of their defensemen, so now you’re playing five ‘D’ all night,” Cassidy said. “Well, make them work in front of their net. Make them expend energy in front of their net. Make them take penalties in front of their net.”
Dallas coach Peter DeBoer played that down. The Stars won the last two games that way and have the last change at home, like they did when Lundqvist played 7:33 in Game 1 and 10:00 in Game 2.
“I don’t think there’s a rule that you have to play six ‘D’ even minutes or anything like that,” DeBoer said. “I think it just depends on the situation.”
3. Desperation
Dallas played with desperation the past two games, not wanting to fall behind Vegas 3-0 in a series for the second straight season. The Stars did just that in the conference final last season and lost the series in six games.
Now they need to seize this opportunity.
“We’ve played this team now last year and this year and have not put them behind in a series at any point, so that’s the goal,” DeBoer said. “Let’s see how they react to that.”
