It has been decades since the Islanders had an owner who wasn’t in it to make a real estate killing or to advance a hidden agenda, or both. But now, with the transition of power from Charles Wang to Jon Ledecky (and Scott Malkin) complete, the business of the Islanders is in trusted hands and the agenda is transparent.

Which is to restore the power and glory of the franchise that once spawned the greatest team in the history of the sport.

Make no mistake. This still is going to be tricky business for an operation that, by choice, straddles Long Island and Brooklyn — and in doing so has lost much of its historical identity while yet to create a new one. Let’s face it: It is not as if the Islanders simply moved from one side of 161st Street in The Bronx to the other (even if that divide always has seemed miles wide).

But Ledecky, who hosted a meet-and-greet luncheon for the media at a tony spot in midtown Manhattan on Wednesday, is not so much straddling a line as erasing one. He is not pandering to Long Island by suggesting a return is in the offing, is not offering false hope that even a smattering of games will be played at a remodeled Nassau Coliseum. Is not holding his nose when he talks about Brooklyn.

“Barclays is our home,” the principal owner said without equivocation and without holding his nose.

(By the way, the last time the Islanders hosted a major event in Rangers’ territory was in 1977, when the team formally introduced its first-round draft pick named Michael Bossy, who at that point people thought was called “Michel.” And that augured pretty well. Of course, Ledecky is not likely to get 50 this year and for the next eight years after that.)

But Ledecky is not being parochial here. Fact is, he cannot afford to be. Ownership has to create a new market without alienating the old one. Not easy. Which is why, when asked whether he considers the Islanders to be a Long Island team or a Brooklyn team, Ledecky answered this way.

“We’re the New York Islanders.”

Success is attained, if not defined, by attention to detail. (When the Devils switched from their Christmassy uniforms to current design, Lou Lamoriello took a seat in the top row in essentially every section of the Meadowlands upper tier to ensure fans in those seats would be able to read the numbers on the players’ sleeves. That kind of detail.) And no detail seems to have escaped Ledecky in his group’s two-year run-up to assuming control of this too-often shipwrecked franchise that is landlocked on the Atlantic Avenue site, to which Walter O’Malley once wanted to bring the Dodgers. Robert Moses said no, you’re going to Queens. O’Malley said no, we’re going to Los Angeles.

The Islanders didn’t go to Quebec and they didn’t go to Kansas City. They went to Brooklyn, which is a whole lot more convenient, if not quite perfect.

Where others cite problems, Ledecky sees solutions.

To spotty LIRR service and issues about travel from the Island: “Why can’t the Long Island Railroad run the same number of trains for regular-season games as they ran for the playoffs? Maybe we should look into running buses from the Coliseum. That’s about our fan base.”

To the widespread complaints about the ice quality at Barclays: “We are hiring a director of ice operations.”

To the issue that arose from within last year concerning inadequate facilities at Barclays for the players’ wives and families: “That makes me cringe. We are going to personalize the experience for the families and make it the best it can be. This year, we’re going to have a suite for the families so they can actually watch the games. And let’s make sure their transportation from Long Island is flawless.”

To a question about the availability of day-care raised by Dr. Brandy Ladd, the wife of 11-year veteran free-agent winger Andrew Ladd with choices, whom the team courted and ultimately signed to a seven-year deal: “We our providing day-care [with an existing facility] adjacent to our training center so the players can bring their children with them, drop them off, and pick them up when they’re ready to go home.”

Brilliant.

“We want to be a world-class destination for free agents,” Ledecky said. “We are going to be world-class in everything we do. The travel. Where we stay. The best everything. We want the Islanders to be a destination franchise.”

This will require a long-term commitment from ownership and from the landlords in Brooklyn. Excellence cannot be built in a day. And Ledecky has less than two years in which in which to impress John Tavares and convince No. 91 he already has arrived at his destination.

But a journey of a thousand miles begins with a single step. And it is just 29 miles from the Coliseum to Barclays.
