Even though he once nixed New York, Hall of Fame shortstop Barry Larkin said he’s “off-the-charts excited’’ about his son Shane Larkin getting out of Big D and landing in the Big Apple, claiming the Mavericks wasn’t the right situation.

Larkin took a shot at Mark Cuban’s organization for not having patience with young players. Shane Larkin, a point guard out of the University of Miami, struggled in his rookie season after breaking his foot last July in summer-league practice and being out more than four months.

“Dallas doesn’t do a good job of developing players,’’ Barry Larkin told The Post in a phone interview from his home in Orlando. “They’re in win-now mode. [Coach] Rick Carlisle doesn’t know how to develop young players, and Shane was a rookie. It always was a struggle for him to figure out what was going on.’’

Shane was dealt in the six-player deal Wednesday as Cuban desperately wanted back his champion veteran center Tyson Chandler despite his recent regression.

“I’m off-the-charts excited because of the passion of New York fans,’’ Barry Larkin said. “I went through the roof.’’

Shane’s father wasn’t excited 14 years ago when he ultimately squashed a deal that would have sent him to Bobby Valentine’s Mets in late July of the 2000 season. Larkin sought a three-year, $28 million extension to approve the trade.

“I was ready to come to New York but I wanted a three-year deal,’’ said Larkin, an ESPN baseball analyst. “Now he gets a chance to play there. Funny how things happen.’’

Larkin said there was a certain shortstop prospect the Mets claimed they were saving the position for.

“They said they had a young guy named Jose Reyes that was soon coming up,’’ Larkin said. “No regrets. It was the right decision, right for my family. I had three young kids and Shane was 7. I didn’t want to go there for three months and then have to leave.’’

Larkin got booed whenever he returned to Shea Stadium. But he loved the stadium so much his daughter’s middle name is Shea.

“I have a love for Shea Stadium and its fans,’’ Larkin said. “I had so much fun with the fans. Yeah they booed me. I was like, ‘I know, I know.’ ”

Last season, Barry made it to only about 10 Mavericks games, but plans to be at the Garden a lot more. “Bristol [Conn., home of ESPN] is a lot closer to New York than Dallas,’’ Larkin said.

His son appeared in just 48 regular-season games with the Mavericks and played just 10.2 minutes a game. He played 10 total minutes in Dallas’ seven-game series loss to the Spurs in the first round of the playoffs.

“It was up and down, hard for him to regain his footing, no pun in tended,’’ Barry Larkin said. “He didn’t have chance to play in the summer league and get in a groove. His confidence was very high and he has a high basketball IQ but there was hesitancy. He was 100 percent sure mentally his ankle was OK, but you always have that reservation in your mind.

“It was a great introduction to professional sports — of the way it really is. A great learning experience for him.’’

Barry hasn’t totally breathed a sigh of relief. He knows the Knicks are stacked in the backcourt and have four point guards on the roster.

“I was cautiously optimistic because I was wondering if they would make another move flipping him in the draft for something else,’’ Larkin said. “I curbed my enthusiasm. And they still could make a move. It’s still wait and see.’’

This time, Larkin is hoping it works out and his son gets his three years in New York.
