New York's belief that it can come back in the series grew after pulling out the win Friday, with Nelson breaking a 3-3 tie with 3:25 remaining in the third period. The Islanders also thought they played well in Game 2, which was tied until Lightning forward Nikita Kucherov scored the winning goal with nine seconds left.
"I think Game 2, we played a pretty good game. We played how we want to play," New York defenseman Ryan Pulock said. "But we've just got to keep building here. It's a long series. Getting that win yesterday was huge. Game 4 is going to be really big too, so we've just got to continue to get ourselves ready for tomorrow."
The Islanders also understand the importance of moving on quickly after each game, win or lose. They have some areas of their game to clean up after letting a 3-1 lead slip away in the third period before rebounding to win Friday.
"I think Game 2 gave us the confidence that we could win Game 3," Trotz said. "Now, you've [gotten] within a game of getting the series tied up. That's going to give us a little bit of a boost, but at the same time, Tampa Bay's been there before, they've been to the conference finals many times. They've got a veteran team as well.
"They're probably getting Killorn back for sure, and maybe Point. We're going to get their best game tomorrow, and we've got to have our best game."
The Lightning lost focus for a stretch in the second period of Game 3, when the Islanders scored twice, and made mistakes in the defensive zone that led to three goals against. So they know that's an area where they need to be better.
They also know what a win would mean. Teams that take a 3-1 lead are 288-29 (90.9 percent) winning a best-of-7 NHL playoff series, including 10-0 this postseason. Since the conference format was adopted for the 1981-82 season, teams with a 3-1 lead in the conference finals are 34-1 (97.1 percent). The New Jersey Devils rallied to defeat the Philadelphia Flyers in the 2000 Eastern Conference Final and then won the Stanley Cup.
"I just think we go in with a mindset of just playing every game like it's a clinching game," Tampa Bay forward Pat Maroon said. "So we've got to find ways to just keep playing the way we're playing. We have a good group in there, we have a good team that knows how to bounce back when a loss happens. … We're going to get a really good Islanders team. They're not backing down, so we've got to find ways to bring our best game tomorrow."
