When Spencer Dinwiddie proclaimed his Nets the better New York City basketball team in August, Knicks fans got triggered. Everything that has happened since the last meeting between the teams — Dec. 8 — has proven Dinwiddie right, but it hasn’t done a thing to ease the Knicks fans’ saltiness.

With the teams set to meet Friday at Barclays Center, Dinwiddie (who likely will miss the contest due to a thumb injury) is still getting backlash on social media from vexed Knicks fans. And in true Dinwiddie fashion, it just cracks him up.

“All the time. All the time,” Dinwiddie said. “They blow up my feed all the time. ‘Bad game.’ When the Knicks do anything of a remote positive nature, I hear about it. Like, that’s not what I argued or even what I said. So, I don’t know. “Is it funny? Of course it is. Here’s the thing, bruh: If I said ‘Hey, you’re ugly’ and you said ‘Hey, I’m rich,’ it doesn’t mean you’re not ugly. It’s like, ‘I never said you didn’t have money. You’re still ugly. Sorry.’ ”

No doubt the Knicks — the NBA’s most valuable team, according to Forbes, which plays in the World’s Most Famous Arena — are filthy rich. But that 10-36 record, second-worst in the NBA, is ugly.

The last time the teams met, at the Garden, they were essentially in the same spot. Two days earlier, they were both 8-18. It’s hard to imagine their fortunes having gone in more opposite directions.

The Nets had a players-only film session that day, and proceeded to beat the Raptors and Knicks on back-to-back nights. They have gone 18-5 since, becoming one of the NBA’s hottest teams and best stories. The Knicks, meanwhile, have lost 18 of 20 since that defeat to the Nets and have become the team others chalk up as a “W,” mollified with damning praise like “Oh, they play hard” — the basketball equivalent of someone being told they have a nice personality.

“We want to win the games we’re supposed to win, and [the Knicks is] a game we’re supposed to win. We want to go ahead and take care of business; we don’t want to leave anything on the table,” D’Angelo Russell said.

“If our focus is on the Knicks, we’re in trouble,” Ed Davis said. “I don’t know how many games they’ve won, but I’m pretty sure they’re getting ready for a lottery pick. That’s not really our competition: We’ve got bigger goals. No disrespect to them, but it is what it is.”

It’s no disrespect: It’s just fact.

The Nets (26-23) have won five straight and come into Friday sixth in the East. The Knicks (10-36, second-worst in the NBA) have lost seven in a row.

“It’s Nets-Knicks. I always think it’s a great thing for the city, state of New York. It’s a different deal. Yankees-Mets. Islanders-Rangers. Jets-Giants. It’s pretty cool,” coach Kenny Atkinson said. “I’m excited for it. I know our fans are.”

The Nets are only averaging an NBA-worst 14,258 of those. Over the years they frequently have seen opposing teams’ fans take over Barclays Center, none more so than Knicks fans. That slowly has started to change during this stretch. Will it be the case on Friday?

“I know it makes [general manager] Sean [Marks] mad when they have those other jerseys in there. He wants to kick ‘em out of the arena, but we can’t do that,” Atkinson said. “So we’ve got to do it not with our mouth but with our actions.”

That could start by fully turning the tables on the Knicks, who swept the Nets 4-0 last season.

“Listen, they’ve dominated us for 2 ½ years I’d say,” Atkinson said. “They’ve owned us quite honestly. We’ve gotten a little revenge lately. This is an important game for us because it’s New York but it’s also an important game because we’re trying to move up the ladder.”

Rondae Hollis-Jefferson is questionable to face the Knicks after straining his left shoulder during Wednesday’s win over the Magic.

“I think they’re doing further check-ups with him,” Atkinson said. “I said it wasn’t bad, but let’s hold off and find out for sure.”

Jared Dudley (hamstring) is also out.

While the Nets are dealing with an injury crunch, they felt empathy for the Pacers, who have lost star Victor Oladipo for the season with a ruptured quad tendon. But that could open the door for Russell to make the All-Star Game.

“D’Angelo’s been playing at an All-Star level,” Atkinson said. “ He’s really in a great place. Let’s face it, we’re winning some games, so there’s credibility behind [it].”
