The Rangers will have five extra days to prepare for opening night on Oct. 12 in Buffalo, and they will need every single one of them.

Learning a third coach’s system in four seasons is an obstacle in itself.

One that may take longer than desired.

At least that’s what Peter Laviolette has planned for.

The insufficient offense has appeared to come as no surprise to the Rangers head coach, who adamantly forewarned that he expected a learning curve as the team adjusted to his style.

So with a bit of a grace period scheduled before the start of the season, expect Laviolette to hone in on details.

“There’s work to be done on everything,” Laviolette said after the final exhibition game Thursday night at Madison Square Garden, where the Rangers fell 3-1 to the Bruins and dropped to 1-5 in the preseason. “I mentioned the five-on-five and the offense and having to crank that up. The first part of camp you’re focusing a lot on five-on-five play and not as much on the power play and penalty kill.

“I do think the power play gets a little bit of an advantage, hit the post a few times. It didn’t drop for us. But these guys have been together so there’s a little bit more rhythm, where the penalty kill it’s a little bit new and a little bit different. So they’re figuring that out.

“We’ll look at the game [Thursday night] and then take it into practice and work on it every day.”

Though it would’ve been beneficial to experiment in game action with Filip Chytil, who has been sidelined for a majority of training camp with an upper-body injury, Laviolette may finally get the opportunity to do so if the Czech center returns to practice this week.

Though Laviolette will probably focus more on further implementing his system and practicing special teams.

The Rangers appear to get just as much out of their regular practices as they do in exhibition games because of their new-found high-intensity nature.

“A lot of things have changed system-wise and obviously a lot of changes around here with personnel,” captain Jacob Trouba said. “So it’s good to kind of get comfortable. You’re not going to flip a switch and it’s going to be magic. I think it takes time to build that trust and those reads and where guys are going and the communication is a little bit different. But I think it’s trending in the right direction for us.”

Trouba noted that with so many guys in camp it was difficult to practice the penalty kill, which has been a weak point for the Rangers this preseason.

The Rangers gave up six power-play goals on 15 short-handed situations, while giving up power-play tallies in four of their six exhibition games.

On the flip side, the Rangers scored just one power-play goal this preseason.

They went 0-for-12 through the first four contests, scored one in their second meeting with the Devils and then finished the preseason with an 0-for-5 showing against the Bruins on Thursday night.

Laviolette appears to be leaning toward keeping the Adam Fox-Chris Kreider-Mika Zibanejad-Artemi Panarin-Vincent Trocheck unit together, but there’s a good chance he will try some different combinations while he has the time to do so.

“It’s not over yet,” Trouba said of the preseason. “We still got a week to kind of keep building what we want to do. We’ve been going over a lot of the systems work and trying to get the systems down and the reads down. I think we’ll probably go more into special teams. I think that’s an area that we can improve on. I think we all know that. We haven’t spent a ton of time on it thus far and I think that’s the next step.”
