CHICAGO — Kevin Durant apparently has a longtime yen for Duke’s RJ Barrett, the player the Knicks could select at No. 3 in the draft and who possibly could become his future teammate.

A 2017 video surfaced from the sports network Overtime in which Durant gives a scouting report on some young high school prospects and comes across Barrett, the Canadian swingman who was playing for Montverde Academy, the prep powerhouse in Florida. TheKnickofTime podcast first tweeted the video Friday night.

“Kid I’ve been hearing a lot about,’’ Durant said while viewing tape. “I haven’t gotten a chance to watch him as much. I know he’s a lefty out of Canada, I think. He’s another of those 6-7 wings who probably do everything, that can guard one through four that can play a long time in the NBA, especially in the NBA today.”

Durant will be a free agent on July 1 with the league-wide consensus the Knicks are early favorites for his services.

The Knicks are considering packaging their No. 3 pick to New Orleans in a trade for Anthony Davis. It would seem Durant would prefer a ready-made superstar as sidekick, but who knows if he’d rather have Barrett and Kyrie Irving instead — especially considering Durant’s rave reviews of Barrett’s southpaw advantage.

“Getting crafty with the left,” Durant said, watching the video on a laptop. “See lefties are tough to guard, man. They can go right better than righties can go left and so a left-hander is hard to guard. He’s a lefty that uses his right, which is gonna help him.

“Shoot the J, OK. Man, he’s athletic, man. He can play out top. That’s the thing. You got to be able to play out top, conduct the offense.

“He’s going to Duke, so Coach K — You already know Coach K is gonna let him rock out.”

Among others, Durant reviewed high schoolers LaMelo Ball, Cam Reddish and Zion Williamson on the video.
