Knicks coach not concerned about losing job

Knicks coach Mike D’Antoni said he is not worried at all about being back next season, though his greatest ally, president Donnie Walsh, is leaving on June 30 after turning down James Dolan’s contract-extension offer.

D’Antoni has the support of Walsh, who will stay on next season as a consultant and Garden sports president Scott O’Neil, and he expects to meet with Knicks owner James Dolan shortly.

It is unclear if a contract extension would be discussed, but one source said Dolan likes D’Antoni a lot. D’Antoni has one year and $6 million left on his contract, and Dolan is not keen on eating it during a lockout-shortened season with revenues down.

D’Antoni told The Post yesterday, in his first interview since the season ended, that he is not concerned about his future with the Knicks.

“No, I feel good,” D’Antoni said. “I hate it Donnie is leaving. I owe a lot to him. We had three good years. He did exactly what he wanted and said he would do and he’s got us in position to be one of the better teams in the NBA next year. That’s to his credit.

“We worked well together,” he added. “I appreciate his support and I feel good about us having a great year next season. It’s all a coach can ask for, to have him give me that chance. He’s put me in that position.”

D’Antoni thought he and Walsh would be together next season, but Walsh is primed to make sure at least D’Antoni will be back, regardless of the new presidential hire.

“I think everyone was a little surprised by it,” D’Antoni said. “Everyone thought they would reach a positive conclusion. But they didn’t and now we go forward. Nothing in sports is surprising.”

D’Antoni spoke with Walsh for two hours Friday moments after the stunning announcement. But he declined to offer up his own spin on why Walsh is gone. Multiple sources said Walsh did not feel comfortable with the contract language regarding full autonomy to hire his successor and backed out of a verbal agreement to return.

“Donnie keeps his cards close to the vest,” D’Antoni said. “There’s probably 1,000 little things, and I do think he missed his family [in Indiana].”

Glen Grunwald, senior VP of basketball and former Raptors president, will become interim president starting July 1 and could be considered for the long-term gig.

D’Antoni said he doesn’t expect more personnel input than usual.

“Glen’s great,” D’Antoni said. “He’s been terrific. He’s experienced and he knows what he’s doing. Donnie will run the draft with Glen like they always do, and I’m prepared to be there to help them out.”

D’Antoni said he will not put his hat in the ring in attempt to add a general manager title when me meets with Dolan. One source said D’Antoni was considering it after having both roles in Phoenix for a couple of years.

“No, I just want to coach,” D’Antoni said. “I’ve done that before. I don’t want to wake up in the morning and have to speak to an agent.”

Walsh spoke glowingly about D’Antoni in his farewell conference call, repeating again how he put his coach in awful position the first two seasons when he kept changing the roster to open cap space.

Walsh did it to D’Antoni again at the trade deadline, gutting the roster in the Carmelo Anthony trade. D’Antoni guided the Knicks to a 42-40 record and their first playoff berth since 2004. The Knicks were swept by Boston after Amar’e Stoudemire and Chauncey Billups got injured. D’Antoni came under attack from some fans after the sweep.

“I felt terrible, as a general manager, I had to put my coach in a position where he didn’t have a chance to win,” Walsh said. “And I can remember looking down, thinking, ‘What have I done to this kid?’ when we were losing.”
