"It's all about managing the game and we didn't need another one," Cooper said. "We just needed to prevent them from getting one. It's not like we sat back, but we were feeling pretty good about our offensive game, at least the possession part of it.
"It's all about, 'Are you adding risk to your game or not?' As we told the guys, we don't need the third one to win. The third one can come on the empty-netter, but let's get us in the position for that to happen and, fortunately for us, it did."
Seattle did get within one at the 10:44 mark of the third, but Tampa Bay got two empty-net goals from Brandon Hagel and Victor Hedman to close out the 4-1 win.
The Lightning continue to place an emphasis on defending their way to wins and they've done that through the first two contests of this season-long, five-game road trip, holding St. Louis and Seattle to three goals combined.
"I think it's been good," said Bolts defenseman Ian Cole when asked about his team's defensive performance. "The season's always a process, even for a team like this that has won so much and had so much success. Every season, you kind of have to start anew, get those reps in, and get everyone on the same page.
"The way we play, it's a five-man, team defense. We really rely on our forwards to do a lot of work for us too and they're so good at it. You've seen the past two games how good they can be and how much they help us as defensemen, and obviously as goaltenders too. They've done a great job for us."
Along with team defense, the Lightning had another strong showing on the penalty kill on Monday, going three-for-three on the PK. The Bolts PK is six-for-seven over the last three contests.
