Knicks fans can begin to dream of their own Big Three after Grizzlies point guard Mike Conley didn’t rule out joining the team as a free agent after this season.

“I think everything will be on the table when the time comes,” Conley said. “I haven’t committed to anything.”

Upgrading at point guard is the Knicks’ top priority, either at the upcoming Feb. 18 trading deadline or in the offseason. Conley reportedly is high on the Knicks’ wish list.

Conley saw his first live action against the improved Knicks and rookie sensation Kristaps Porzingis in Friday night’s 91-85 Grizzlies win at Madison Square Garden, scoring eight points and getting nine assists in 31 minutes. Conley missed the first game between the Knicks and Grizzlies on Jan. 16, a 103-95 Memphis win, because he was recovering from a strained left Achilles.

Conley is impressed with what he has seen so far from the Knicks.

“They obviously have a lot of potential,” the 28-year-old said before Friday’s game. “They came to our house and had a very good showing and played well. The big fella [Porzingis] played well against us, now they have Melo [Carmelo Anthony] back. It is going to make them even more of a threat.”

The praise wasn’t one-sided.

“He’s one of the best young guards in the league, but it’s hard to call him young [anymore] because he’s been around a while,” Knicks coach Derek Fisher said of Conley. “A very, very good basketball player on both ends of the floor.”

It is believed Memphis has the inside track to re-signing Conley because of his relationship with center Marc Gasol. The Grizzlies drafted both in 2007. Conley hounded him during his free agency last summer to stay in Memphis. He said they have grown up together and know nothing else, but there is no “pact” between them to remain teammates.

“At the end of the day, it is a business and anything can happen,” Conley said. “But obviously they know how I feel about Marc and my teammates.”

Conley has played all nine of his NBA seasons in Memphis. Entering Friday, he was averaging 14.6 points, 6.1 assists and 3.0 rebounds per game for a Grizzlies team that is now 30-20 and in fifth place in the Western Conference.

Conley said he wouldn’t be intimidated by playing in a big market. He called playing any game at the Garden a “special opportunity” and “one of the places you grew up wanting to play at.” He sees a lot of upside in the Knicks roster right now.

“They’ve got talent,” he said. “Obviously Porzingis surprised a lot of people. He is going to be very, very good in this league. He already is pretty good, but he is going to grow each year, and they already have one of the best small forwards in Melo.”

If the Knicks are going to lure Conley to New York, they likely will need to free up some salary-cap space. The team currently would have $18 million in cap space this offseason, and Conley could fetch a max contract. The Knicks can free up some more cash — around $3 million — by using the stretch provision on starting point guard Jose Calderon.

When the season ends, Conley will shift his focus to what’s next.

“When the offseason comes, you make the decision with your family and do what’s best for you and the situation,” Conley said. “I’m just going to keep it at that, focus on the season and see what happens in the offseason.”
