ORLANDO — The Nets traded veteran forward Dorian Finney-Smith to the Lakers for draft picks — and the return of the prodigal son.

Brooklyn sent Finney-Smith and backup Shake Milton – who recently came off the bench – to Los Angeles for three second-round picks, Maxwell Lewis and former Net D’Angelo Russell. The Nets will get the Lakers’ second-rounders in 2027, 2030 and 2031.

The news was first reported by ESPN and confirmed by The Post.

Russell — averaging 12.4 points and 4.7 assists — was a key linchpin of general manager Sean Marks’ initial rebuild in Brooklyn before being moved as part of a sign-and-trade for Kevin Durant.

It remains to be seen whether he will be part of this second rebuild. And whether he still feels uncomfortable about being traded away the first time.

In Finney-Smith, the Nets traded their strength on the court and the adults in the room. He had one of the best seasons of his career, leading the team with plus-41, while no other Net was better than plus-2 before Sunday’s game in Orlando.

Finney-Smith is shooting a career-high 44 percent from 3-point range. But he had a player option for next year that he likely wouldn’t exercise, meaning he could have hit unrestricted free agency for nothing in the summer.

Marks and Nets owner Joe Tsai had an offer for two first-round picks for Finney-Smith as soon as they acquired him from Dallas for Kyrie Irving. But they were trying to keep up behind the Mikal bridges at the time and had no interest in a demolished reconstruction.

But times have changed.

Now they’re rebuilding and Russell could be there again. They had acquired the young point guard from the Lakers and molded him into an All-Star. He helped lead them to the playoffs in 2018-19 but was traded in the summer of 2019 as part of the deal to sign Durant.

When asked in 2021 if he was particularly motivated to play against the Nets, he said no, but certainly would be if Marks played.

“If Sean Marks wore a jersey, maybe something would be different,” Russell told The Post. “But he’s not.

“It’s part of the league. Obviously I’ve been traded before, so I’m sure I could be traded again. I try not to get too comfortable. You know, I know you can wake up every day and get that call, so my bags are packed.”

Russell has an expiring contract that pays him $18.7 million. He will be an unrestricted free agent in the summer.

Brooklyn is currently starting Ben Simmons at point guard on an expiring $40 million contract.
