And they'll certainly be spending some time over the next two days thinking about the two-man advantage they had for 38 seconds in the third period, when they couldn't muster a shot on goal with Lightning defenseman Ryan McDonagh and forward Cedric Paquette in the penalty box.
"When you have a 5-on-3, you want to capitalize," said Nelson, who missed the remainder of the first period after the hit from Killorn but returned in the second. "You have like 38 seconds, so plenty of time. You're hoping to get a look there. That can be a difference-maker in the third.
"It stings giving one up with [nine] seconds left, there's no denying that. With that said, we played a pretty good game to give ourselves a chance. We have to find a way to turn the page, kind of build off that, feed into some more of the game plan and some structural things to give ourselves a chance to win the next game. You just have to focus on that and winning that next one. That's the biggest thing we can do."
The power play will have to contribute if the Islanders plan on getting back in this series and advancing to the Cup Final for the first time since 1984. Trotz said he believes they're looking for that extra pass when they need to fire away and have more bodies in front against one of the best goalies in the NHL.
"We're trying to get a little bit too fine I think," Trotz said. "Sometimes you've got to get a little greasy, and we were trying to pass it in the net tonight a little bit. When we had a few good looks, Vasilevskiy was pretty big. We had a 5-on-3 and didn't take advantage of it. It was only 38 seconds, but they got through that.
"We had some chances. We've had some breakaways we haven't scored on, we've had some 2-on-1s we haven't executed quite on, or tried to pass it on net. We're going to have to shoot the puck more and get greasy."
The Islanders never trailed in a series this postseason until Monday. Now the mountain has a steeper climb, especially against a Lightning team that found a way to win Game 2 despite being without Killorn after his penalty and forward Brayden Point, who did not play in the third period.
"We've believed that we can win this series, and we still do," Martin said. "It's a good effort. Unfortunately we came up short, but you play like that more often than not, you're going to win. Some positives we can take from this, but obviously not the result we wanted."
