If you can get a star, go for it.

That’s the advice for the Nets from two winners who have been there, NBA stars-turned broadcasters Reggie Miller and Kenny Smith.

The Nets’ most recent championship window closed when they traded All-Stars Kevin Durant and Kyrie Irving in February, in exchange for Mikal Bridges, Spencer Dinwiddie, Cameron Johnson, Dorian Finney-Smith and a boatload of draft picks.

But if they want to pry a new window open, they’re going to need not just promising up-and-coming talent, but proven All-NBA talent, whether that’s through a trade for the Trail Blazers’ Damian Lillard or trading for or signing somebody else.

“For me, anytime that you can, you can get a player who is going to be top three in his position, you have to try to do that,” Smith said Thursday.

“There’s top three players in that position, and then there’s generational talent, and if you have an opportunity to get either one of them at any stage of their career, you have to go for it. I don’t know what that means, I don’t even know who’s available.

“I think Brooklyn has been in this position before. And that’s how they attracted the first stage of free agency. They had a nice young nucleus that was good enough to maybe make the playoffs when they had the first run with Dinwiddie and Joe Harris and all of those guys, and now they’re in that second stage of doing the exact same thing. But the object is, do we have a guy who’s going to be a top-three player in his position? They don’t have that yet. So yeah, if that’s available, I think that’s the goal.”

Smith, an Archbishop Molloy product who won two titles with the Rockets, is a studio host of TNT’s Emmy-winning “Inside the NBA.”

The Hall-of-Famer Miller, one of the most prolific 3-point shooters in NBA history and a proven playoff performer, is a TNT analyst now working the Eastern Conference finals between the Celtics and Heat.

Miller worked the Nets’ first-round loss to the 76ers, and saw exactly how much they missed Durant, or another All-NBA scorer.

“I will say that we covered that Philly-Brooklyn series. I love me Spencer Dinwiddie, I absolutely [do],” Miller said. “ Mikal Bridges, we saw his work when he was with Phoenix. Having since been traded, obviously his numbers went up, and we saw what type of value he is going to bring to that organization. Same with Cam Johnson But watching that series, I said to myself, if they had a true No. 1, then this team would be a different team. You would discuss Brooklyn in a different light.

“Whomever that No. 1 may be — you mentioned Damian Lillard, there’s other names I’m sure I can float around, but I just don’t want to start anything. If they had a true No. 1 on that team, where these other guys like Dinwiddie, Cam, Mikal — very much the same role they played in Phoenix when Chris Paul and Devin Booker were the No. 1 and 2 options in how they played — you would think and approach Brooklyn a different way.”

Since the 1990-91 season, 30 of 32 champions have been led by a past or future MVP, with the Raptors in 2018-19 and the Pistons in 2003-04 the only exceptions.

And Miller, pointing out the Eastern and Western Conference finals — with LeBron James versus Nikola Jokic and Jayson Tatum versus Jimmy Butler — suggested the Nets will need a Lillard-level player to get at least to that level.

“I personally believe each team [needs one]. Just look at the Final Four right now, every team has a dog, right, a guy that you throw the ball to go win the ballgame for us,” Miller said. “Historic 51 [points] for Tatum. Jimmy Butler, who you saw [Wednesday] night. Jokic, you saw Game 1 and what he’s done over the last two years when he was back-to-back MVP. And again, the best player of his generation, and LeBron James and Anthony Davis, right?

“Brooklyn doesn’t have that type of player. If they did — with those players we just mentioned — we’d be looking at them different. And it’s New York City. You’ve got to have a marquee-type player in that city. So if you get a chance to go get a No. 1 and build around that No. 1 with these guys, then you go do it.”

Nets assistant coach Royal Ivey will join Ime Udoka’s staff in Houston, according to ESPN.

Udoka and Ivey were both Nets assistants in 2020-21 under Steve Nash. Ivey, a New York City native, was close with Durant.

Both played their college ball for Texas.
