Jeremy Lin hasn’t played a single regular-season game for the Nets, but already he is the most popular player in their admittedly brief Brooklyn history. He has comedy. He has charisma. But if the Nets are going to win games, Lin needs chemistry.

If the Nets are going to avoid, as predicted, being the NBA’s worst team, Lin is going to have to form a rapport with Brook Lopez. And Brook-Lin is showing signs of developing chemistry, both on and off the court.

“He makes everybody better,’’ Lopez gushed.

Lin said, “That requires a lot of understanding my teammates and getting a good chemistry and flow.”

Despite a dearth of opportunities to run the pick-and-roll together this preseason as coach Kenny Atkinson force-feeds his motion offense and pares down a 20-man roster, the rapport between Lin and Lopez is growing … even in comedic ways.

While Lin was being interviewed on Wednesday, Lopez wandered over and put his arm on his point guard’s shoulder.

“Yo, let’s do [the interview] together. Come on,” Lin said.

“Yeah, I like that,’’ said Lopez. “Isn’t this a good embodiment [of the team], right?”

The Nets hope so.

The Eastern Conference’s top-scoring center last season, Lopez is averaging just 7.0 points per game this preseason on .407 shooting as he adjusts to a quickened pace and motion offense that has left him with few post-up opportunities.

Playing together more often with Lin in Thursday’s preseason finale against the Knicks seems like a must.

“I’d think so,’’ Lopez said.

While Atkinson still is tinkering, he also wants to get things settled.

“I think I’m going to look more at our regular-season rotations. I still want to get some other guys some time … but I definitely want to see our regular rotation for longer stretches,’’ Atkinson said. “We obviously want those guys playing together a lot, but we also want to see Jeremy with different guys.”

The motion offense appears to have agreed with Lin so far. He’s averaging 15.5 points on torrid .606 shooting and .471 from 3-point range, with a team-high 18 assists.

“I’m much better than where I was in training camp last year in terms of my shot,” Lin said. “I’m more confident in it.

“A lot of times you’d see me passing it up or hesitating; but here I’m shooting every open 3, and that gives me more space to be able to drive the ball. It allows me to be able to play where I don’t have to be the one playing pick-and-roll every time. I can find space on the weak side and be a threat in a different way.”

Lin has entertained Nets fans in different ways, from being one of the most-followed players on social media to an upcoming appearance in the comic book series, “Totally Awesome Hulk.”

On Tuesday afternoon Lin was playing the lead in a Comedy Central video called Viralocity. He refused to play pickup basketball in a diaper, instead opting to ostensibly surprise “fans” outside Barclays Center in a hilarious sketch.

“It was pretty funny. It was a lot of fun. The reactions were [hilarious]. The funniest part was seeing the bystanders who didn’t know what was going on, seeing their reactions,’’ Lin said. “The funniest thing was seeing people on the side saying, ‘Oh, my god.’ It was funny.”

What could be funnier would be an encore, with Lin inviting Lopez to shoot another video with him in the future.

But the Nets’ immediate future depends on them working together on-court.
