"You have to score to win games, but we've been through the playoffs before and, in the end, you also have to keep the puck out of your net," Tampa Bay coach Jon Cooper said. "You can throw all those defensive cliches out there, but that's ultimately what has to happen because it's so tight-checking."
The Lightning led the NHL in goals (290) and road goals (145) during the regular season.
"Goals are at a premium (in the playoffs), and when you play defense and frustrate teams, don't give them chances, that's big," Cooper said. "Especially with some of the snipers we have, we'll take our chances."
The Lightning held Devils left wing Taylor Hall to a series-low one shot on goal in Game 4. He averaged 5.7 shots in the first three games and has two goals and four assists in the series.
"He's a world-class player and has had a tremendous year, so for us try to shut him down was a big focus and we did a good job," Tampa Bay defenseman Victor Hedman said. "Anton Stralman and Ryan McDonagh were working against him most of the night, but whoever was out there did the job. Now we have an opportunity to go home and make it count."
The Lightning penalty kill, which ranked 28th in the NHL during the regular season (76.1 percent), killed five of six power plays Wednesday and ranks fifth in the postseason at 83.3 percent (15 for 18).
"We really turned the penalty kill around; it was a little bit of a struggle in the regular season," Hedman said. "We made some adjustments and guys are buying in, blocking shots, and allowing [goalie Andrei Vasilevskiy] to see the puck. We're putting pressure up ice when we have the opportunity, and it was huge.
"It's all about dedication; you have to take pride in being on the PK, and guys showed that."
Vasilevskiy made 25 saves after Kyle Palmieri scored on New Jersey's third shot of the game.
