Nets veterans Deron Williams and Joe Johnson may not want to buy in Brooklyn.

If Williams is still the face of the franchise and Johnson still part of a so-called Brooklyn Big 3, there was no evidence of it in a letter sent out Friday to Nets season-ticket holders and sponsors and written by general manager Billy King and CEO Brett Yormark.

In a letter obtained by The Post, King and Yormark wrote they visited owner Mikhail Prokhorov two weeks ago in Moscow to “discuss the state of the team.’’

King and Yormark stated the Nets have plans to re-sign Brook Lopez and Thaddeus Young “to keep our core leadership together.” They stated they wanted to “build on our emerging young core,” mentioning Mason Plumlee, Bojan Bogdanovic, Markel Brown and Sergey Karasev. They mentioned their two draft picks — Nos. 29 and 41 — and a desire in “purchasing’’ another pick.

But King and Yormark made no mention of Williams and Johnson — omissions that can be taken as an ominous sign for the duo. It’s unclear if either Williams or Johnson has requested a trade.

In the letter, King and Yormark wrote the owner “is 100 percent dedicated to delivering a winning product on the court.’’

The letter also revealed plans to announce an affiliation with a D-League team “in the coming weeks’’ and a planned opening of their Brooklyn practice facility as they get out of New Jersey completely.

“Brett and Billy are very transparent with season-ticket holders,’’ Nets chief communications officer Barry Baum said in confirming the letter. “We continue to be a very accessible franchise. After the trip, they wanted our fans to know what’s on ownership’s mind and our plans going forward.’’
