So what’s the chances of another ex-Knick named Jackson making the move back to New York City? Barring a late-season collapse, Warriors coach Mark Jackson will guide Golden State to its second straight playoff berth. But if the team doesn’t advance at least to the second round, there’s a distinct chance he could be a coaching free agent and available if new president Phil Jackson wants him. Rumors he has worn out his welcome with Golden State owner Joe Lacob abound because of Jackson’ s headstrong personality. The Warriors sit in sixth place in the West, but were only three games out of the ninth seed at 45-27 before hosting the Knicks Sunday night. Jackson, in his third season as head coach after a successful stint as a national broadcaster, has guided the Warriors to consecutive 45-win seasons for the first time since the mid-1970s. Stephen Curry swears by Jackson and made over-the-top supportive remarks about him in recent days — remarks Carmelo Anthony hasn’t come close to uttering about lame duck Mike Woodson. But Jackson is viewed in some circles as a lame duck. He has one year left on his pact but there have been no contract-extension talks, and tension reportedly exists between him and the front office. His latest tiff with assistant coach Brian Scalabrine, whom he demoted to work with the D-League team, created something of a national stir. Scalabrine apparently wanted too much say in matters. One Bay Area columnist wrote of Jackson, comparing him to the ill-fated Niners coach Mike Singletary: “Both made repeated grand statements, fused with religious overtones, and that doesn’t always play well forever, particularly in the Bay area.’’ There’s speculation in the Oakland media Jackson’s big personality and my-way-or-highway style won’t work over a long period. However, former Knicks coach Jeff Van Gundy, one of Jackson’s pals, think it’s nonsense. “Look at the results,’’ Van Gundy told The Post. “They were horrible before he came, now they are excellent. He has developed players. They defend. If the media has a problem with winning, then I guess the alternative is to lose again like they did for the previous 15-20 years. I don’t understand what there is to complain about, seriously.’’
