The Nets extended a qualifying offer to Cam Thomas Sunday afternoon to make their leading scorer a restricted free agent, sources told The Post. 

They did not extend qualifying offers to either Day’Ron Sharpe or Ziaire Williams, making them unrestricted free agents.

But the team still is interested in re-signing them, according to sources close to the situation. 

Thomas will become a restricted free agent and have a cap hold of $12 million.

He will end up earning well over that, but how much over?

He’s a unique case, and league front office personnel are divided as to what his value is. 

Those who spoke with The Post suggested he’ll earn over $20 million annually.

ESPN Insider Bobby Marks, a former Nets assistant GM, suggested Saturday that Brooklyn could re-sign Thomas to a three-year, $54 million contract. 

“What is his number in free agency? Is it 20-ish or somewhere around there? Consider it comparable to the Anfernee Simons contract that he signed about three years ago,” Marks had said earlier. “Remember, Brooklyn has the right to match any offer sheet. You have leverage in the process until a team comes in with money, and who is that team going to be?” 

Thomas averaged a team-high 24.0 points and a career-best 3.8 assists last season, and at just 23 years old, he is Brooklyn’s best young(ish) player.

But the shooting guard was limited to just 25 appearances due to repeated hamstring woes, hit just .349 from behind the arc and is questionable defensively. 

“It’s a business, but at the end of the day, I’d love to be back. I was drafted here, so I definitely have a connection,” Thomas said in March. “But whatever happens happens. I’m gonna let my agents and the front office discuss that. We should be good, though. I’m very confident and happy to be back if I am back. So we’ll see.” 

The Nets still have Bird Rights on Sharpe and Williams and can work out deals later with few teams other than the Detroit Pistons having legitimate cap space. 

Sharpe, who would’ve had a cap hold of just over $11.9 million, averaged 7.9 points and 6.6 rebounds this season in just 18.1 minutes.

He’s on pace to have the most rebounds per 100 possessions in NBA history.

With the value of extra possessions on display this postseason, Brooklyn will look to re-sign him to a number below that cap hold, perhaps as quickly as early as next week. 

Not extending qualifying offers to Sharpe ($5.98 million) or Williams ($8.74 million) just gives Brooklyn more cap flexibility to use in free agency, either taking on more salary dumps to acquire assets or perhaps pursuing free agents like Memphis’ Santi Aldama. 

The move implies there is at least one more shoe to drop. Maybe more. 

“The Brooklyn Nets would’ve risked losing $14 million in cap space by tendering Day’Ron Sharpe and Ziaire Williams their qualifying offers,” cap expert Yossi Gozlan said. “They could re-sign them to salaries below their respective cap holds to maximize their cap space [and have $45 million-$52 million] in cap space right now.” 

Creating the higher end of that range would require waiving Keon Johnson, Tyrese Martin, Drew Timme and Jalen Wilson, all of whom had their options picked up Saturday but are not guaranteed.

Still, the Nets have cornered the salary cap market, presumably for a purpose. 

Aldama has been a potential restricted free agent target for the Nets. He’s a Spaniard like coach Jordi Fernández and fits their timeline at just 24. 

Marks suggested a two-year, $40 million offer sheet for the versatile defender, who could blossom offensively outside the shadow of Ja Morant and Jaren Jackson Jr. 

Otherwise, expect the Nets to leverage their cap room by taking salary dumps. Could they get a couple of second-round picks from the Grizzlies to take Cole Anthony (whose filmmaker mother Crystal McCrary is close with Nets owner Joe Tsai’s wife, Clara)? Take Duncan Robinson to facilitate a Jonathan Kuminga deal to Miami? 

Whatever the deal, expect that sort of strategy in the coming days.
