Bo Horvat’s struggles following the blockbuster deal that brought him from Vancouver to Long Island don’t seem to concern Lou Lamoriello too much.

Though the Islanders’ president and general manager acknowledged (as Horvat did on breakup day) that the center’s production wasn’t what it should have been, there is confidence Horvat will play to expectations next season.

“He was on a 50-goal clip, but we know of what he should be. He should be a 30, 35 goal scorer,” Lamoriello told reporters Tuesday. “I think that what transpired when Mat [Barzal] got hurt, I think we overused him. I think he played too much.

“Not second-guessing or questioning the decisions to do that, because it [was] necessitated. He was killing penalties, he was power play, he was five-on-five and taking every key faceoff draw.”

Horvat averaged 20:06 per game over the 23 matches Barzal missed for the Islanders — less time on ice than he played per game in Vancouver — though there is a large difference between the first 10 games (21:50) and the last 13 (18:45).

In any case, Horvat, who scored 31 times with 23 assists over 49 games with the Canucks, scored just seven goals with nine assists in 30 games with the Islanders.

His struggles continued into the playoffs when he scored just once in the first-round series loss to the Hurricanes, late in a blowout Game 3 victory. On breakup day last month, Horvat said the cross-country move had a lot to do with the struggles.

“It was a lot this year, I’m not gonna lie, mentally, not knowing what was gonna happen, not knowing where I was gonna be, how my family was gonna get here,” Horvat said. “And then when everything happened, it was just a big tidal wave of emotions, everything going on, moving the family, living situations and all of that stuff. I’m not trying to make excuses by any means, but it was a lot this year on myself and the family.

“Obviously, would I have liked to score more goals? Of course. I definitely hold myself to a high standard and hold myself accountable and expect a lot out of myself and when the goals did dry up, it was frustrating. It’s something that I think is gonna make me better in the long run, mentally and as a player.”

The Islanders’ depth down the middle — Horvat, Barzal, Brock Nelson, Jean-Gabriel Pageau and Casey Cizikas are all natural centers — is something Lamoriello likes about the roster, though it will likely continue to necessitate Barzal playing right wing if nothing changes. If Barzal and Horvat can find chemistry on the top line — something they seemed to have during the regular season, but not in the playoffs — everyone will be happy with that concession.

Horvat inked an eight-year extension that pays him $8.5 million annually following the trade, so the pressure is on him to perform. The 28-year-old said that much of the offseason will center on completing a move that was done quickly in-season to accommodate the demands of the schedule.

“Obviously focused on getting better on the ice, too, it’s gonna be a big focus and trying to be ready and in as best shape, mentally ready to go for next year, for hockey-wise, but yeah, getting the family moved in, getting ourselves comfortable is a big priority of ours, too,” Horvat said. “Cause the instability of all of this year of the unknowing and where we’re gonna be, definitely like I said, it weighed on us. But looking forward to starting next year already.”
