Seguin gave the Stars a 1-0 lead at 7:59 of the first period with a shot from the high slot.
“It’s early in the year and you get points by getting to your game quicker and having a great goaltender. That’s what’s happened in the first two games,” Seguin said.
The line of Seguin, Matt Duchene and Marchment has factored in on four of Dallas’ seven goals in the first two games.
“[My line got] lots of experience last year during the regular season. We love to communicate,” Seguin said. “We work with each other in the summer on our game, and nice to see some rewards from that.”
Benn made it 2-0 at 10:58 of the second period. Two Islanders players overskated a loose puck in the slot, allowing Benn to collect it before beating Varlamov blocker side with a shot off the post.
“The chances they got, we made mistakes to give them that,” Islanders captain Anders Lee said. “I think we turned back a few too many times. But other than that, it was a low-chance game with two goalies playing good hockey. We didn’t get the bounce we needed to just give us one, but you can’t have many mistakes against this team, and just a couple that cost us.”
