The New York Islanders insist they don’t think about how well they are playing. They are too busy preparing for their next opponent.

However, win after win after win has added up to a point streak the franchise hasn’t seen since its Stanley Cup dynasty days,

Since opening the season with three losses in four games, the Islanders are 14-0-1 while matching the team points record set during a 15-game winning streak from Jan. 21 to Feb. 21, 1982, in the midst of their run of four straight Cup titles (1980-83).

“The teams they’ve had in the past, they’re legendary teams,” coach Barry Trotz said. “I don’t know if it means anything right now because we’re so focused on just the next game and then just this season. I think when you look back, when you’re done, you can say, ‘Hey, remember that streak we had?’”

The Islanders have earned points in 15 straight games for just the fourth time, with the previous three coming long before teams earned a point for losing in overtime and long before shootouts (1978, 1980 and 1982).

They have pulled it off different ways. The Islanders have given up the first goal seven times, trailed after one period four times and after two periods twice. They won three times in overtime and twice in shootouts. At Philadelphia on Saturday, the Islanders trailed 3-0 in the third period before scoring three times in the last 12:14 to tie it and then winning in a shootout. At Pittsburgh on Tuesday, New York scored twice in the last 4:19 to tie the score 4-4 before winning in overtime.

The two comebacks made the Islanders the first team in NHL history to win consecutive games in which it trailed by multiple goals in the final seven minutes of regulation.

“There’s going to be games when you’re down in the score and you have to find to kind of get back in the game,” said veteran forward Derick Brassard, who has had a resurgence in his first season with the Islanders.

Trotz, in his second year in New York, has repeatedly said his players are so focused on the upcoming game they wouldn’t know about it except for reporters.

“The media seems to keep bringing it up, so we’re understanding the numbers now,” he said, “but really the mentality has been just look at the next game.”

Mathew Barzal has led the way with nine goals, but seven other players have scored at least three goals in the run. The goaltending has been stellar, with Thomas Greiss 7-0-0 with a 1.69 goals-against average and Semyon Varlamov 7-0-1 (2.45 GAA).

“We have a group of people that put a great plan in place for us and then we’ve got a group of guys who have committed themselves to going out there and executing that plan 100% of the time,” veteran forward Cal Clutterbuck said. “It’s never perfect but our goal is to make sure that mental errors don’t get in the way of us winning hockey games, and I think we’ve been able to do that over time.”

To set a new team point streak record, the Islanders will have to do it against the Penguins in the back end of the home-and-home set Thursday night. Pittsburgh is responsible ending New York’s two longest winning streaks — the 15-game run in 1982 and the 10-game stretch earlier this month on Nov. 7. In that loss, the Islanders took a 3-0 into the third period at home before the Penguins tied it and then won in overtime for New York’s only blemish since Oct. 11.

The Islanders were a surprise team last year, reaching the playoffs in the first year under Trotz and president and general manager Lou Lamoriello. New York led the Metropolitan Division for a chunk of the season before finishing second and then reaching the second round. After the Islanders returned largely the same team this season without any big-name additions, many predicted a regression.

The Islanders are proving their doubters wrong again.

“Anyone that doubts us can doubt us, that’s up to them,” Clutterbuck said, “but there’s no doubt in here.”
