It won’t be as difficult as the triangle, but Knicks coach David Fizdale said his 2019-20 offense will be more complex.

He’s ready to dig deeper. The thicker playbook will be due to the Knicks having more veterans than they did last season, when Fizdale felt the young squad couldn’t handle complicated schemes. Fizdale admits simple pick-and-rolls and isolations were the norm.

Fizdale’s first-season goal was meeting the trend as a run-and-gun club, and it didn’t necessarily pan out. The Knicks finished 17th in pace, according to NBA.com. Oh, and Fizdale’s crew was last in scoring (104.6 points per game).

Fizdale declined to name his new offense and he has yet to install the new plays, but seems resigned to having an identity in the halfcourt. So far, defense has been the theme of camp and the coach’s offensive focus has been on rudimentary fastbreak drills.

The detailed halfcourt sets will come later in camp. The Knicks open their four-game preseason schedule Monday in Washington. Fizdale already has talked about stealing plays from the French national team’s playbook to unlock Frank Ntilikina.

“I know I want to get the ball over halfcourt quickly,’’ Fizdale said. “I want to get the ball moving. I want a lot of guys involved in the game with the understanding of whoever’s got it going that night, we’ve got to keep that guy going. We’re going to be an attacking team, a team that gets into the paint. We want to be a team that gets to the foul line.”

Fizdale said he didn’t have post-up players during last season’s 17-65 wreckage, but it is different this season. Marcus Morris said the Knicks will pay “bullyball.’’ Julius Randle, Bobby Portis, Taj Gibson and Morris all can maneuver on the block – and 6-foot-7 rookie swingman RJ Barrett can, too.

The Knicks seemed predictable last season in late-game situations with the score close.

“We didn’t have a lot of post-up options,’’ Fizdale said. “Especially after Enes (Kanter) was gone. So it was much more pick-and-roll and open attacks.”

Earlier this week, Fizdale mentioned the Knicks hope to have “way more diversity’’ on offense and talked about more elaborate screening and “different motion movements.’’

With the youngest team in the NBA in 2018-19, Fizdale said he employed Offense 101. Now he believes he’s coaching “a group more ready to win a little more than last year.”

“Last year, I didn’t think we could retain a lot of complication,’’ he said. “It was just trying to teach them basic spacing. I just feel like with the young kids being a year older and the guys that we brought in coming from places that they had some really good offensive coaches, I felt like this group could handle more stuff — the different moves, cutting. They’re picking it up pretty good.’’

Second-year man Kevin Knox says Fizdale has yet to teach most of the playbook.

“He hasn’t really put plays in yet,’’ Knox said. “Everyone is doing a good job adapting to the new offense. We’re just trying to get to know each other. Point guards are trying to get to know all the players’ movements. So (we’re) just playing more freely right now, just getting up and down trying to pass the ball and share the game.”

In the new NBA era, the 3-point shot is deemed paramount. Only nine teams last season shot fewer 3-pointers than the Knicks, who launched 29.5 attempts per game. Fizdale wants to increase that as Knicks general manager Scott Perry added a few more deep shooters.

“We weren’t drawing enough double teams to really manufacture great shots, and so we took our 3s when we got them,” Fizdale said. “Hopefully this year we can get more of that high-percentage 3-point shot.”

But Fizdale is hardly a 3-point fanatic and thinks the roster’s strength could be elsewhere.

“Putting pressure on the rim is the No. 1 priority,’’ Fizdale said. “I think that’s what creates everything else. We got more 3-point shooting, so I expect for us to maybe shoot a few more 3s and make a few more. But if guys have good pull-up jump shots, I want them shooting that shot with confidence if they’re open.

“I don’t see us being one of those teams that’s just running everybody out of the gym,’’ Fizdale added. “I would like to see us have a hard-nosed defensive mentality that can get us out into the open court.”

The Knicks proved to be effective at that last season. According to the Athletic, the Knicks posted the 10th-fastest average possession off turnovers.

Last season, Fizdale talked a lot about ball movement, but isolation too often reigned.

“I want everyone to feel actively involved in the offense,” Fizdale said.
