It’s fitting Frank Ntilikina’s final days as a Knick may be spent holed up in Dallas, where he could have started his NBA career.

With Thursday’s draft night approaching, Ntilikina could still be on the move as the Knicks are extremely open to trading him for another draft pick – either a late first-rounder or second-rounder.

Part of the reason the Knicks are listening is Ntilikina, as the eighth pick in the 2017 draft, will make $5 million next season. The jury still is out if he’s a starting NBA guard after two underachieving seasons.

The Magic and Suns have expressed interest in the past in Ntilikina but that was before he played just 43 games last season with a recurring groin strain.

San Antonio’s Gregg Popovich has heaped praise on the playmaking point guard from France. Had the Knicks taken Dennis Smith Jr., Dallas would have snatched up the 6-foot-6 Frenchman with the ninth pick.

Now the Knicks have both — Ntilikina, 20, and Smith, 21. Because of various injuries to each player, neither got on the court together late last season to determine if they made a potent tandem.

“They can probably get a second-round pick for Frank,” one NBA talent evaluator said. “But there is concern about that old French mentality of being soft.”

The Knicks have the 55th pick in the second round. Knicks brass is feeling its oats after snatching Mitchell Robinson last June in the second round and inking undrafted Allonzo Trier.

The Knicks, too, have a glut of guards. Knicks coach David Fizdale has fallen in love with gritty point guard Kadeem Allen, whom they have locked up on a two-way contract for next season.

Ntilkina’s offseason has been one of mystery. He spent loads of time in France following the season finale on April 11. He changed agents and it is believed he came back to the US only last week.

Ntilikina has not been at the Knicks headquarters in Tarrytown but instead is working with a trainer in Dallas. It’s unclear if his French trainer, Bateko Cisco, is with him.

Following his rookie season, Ntilikina was back in France only until May 20 and returned to Tarrytown to work with coaches after gaining an inch and putting on muscle weight.

Last spring, Ntilikina also went to an NBA Eastern Conference Finals playoff game with Fizdale. (This June, Allen was to go to the NBA Finals with assistant Keith Smart, Trier and Kevin Knox, but Allen’s flight got cancelled).

In his two seasons, Ntilikina has averaged 5.9 points on 35.4% shooting, earning his minutes with solid defense and his 7-foot wingspan.

Ntilikina left Creative Artists Agency for French agent Bouna Ndiaye. The agent is a close family friend of Knicks scout Makhtar Ndiaye, both of whom grew up in France.

According to a source, Ntilikina was unhappy with not getting big-enough endorsement deals compared to other lottery picks.

Another French source said the new agent has worked hard with Ntilikina in recent weeks in terms of “deprogramming him.’’ Ndiaye told The Post last month Ntilikina still wants to be a Knick.

To date, Ntilikina has yet to meet expectations but got a raw deal in getting drafted by ex-president Phil Jackson to run the triangle, then seeing him fired days later.

Ntilikina has plenty of time to reverse his career. He turns 21 in July and some team could get a French steal if he says au revoir to New York on Thursday.
