Chris Mullin was there in Oakland when it all began for Jason Kidd, who used to attend Warriors practices while in high school. “By the time he was in ninth grade, he was like the Pearl Washington of New York, he was so well-known,’’ Mullin told The Post yesterday. “And he kept getting better. I thought he’d level off, but he never did. He was incredible in high school.’’ Mullin, the Hall of Famer out of Brooklyn, is admiring the Knicks’ renaissance season from afar, still living in the Bay Area. Mullin is scheduled to broadcast his first Knicks game Sunday for ESPN Radio when they host the Clippers, but his flight to New York has already been cancelled because of the potential blizzard and he’s scrambling to find a way to get there. The Knicks (31-16), coming off an aberration of a loss in Washington, face the Timberwolves tonight at Target Center and are also concerned about their flight home tonight. Mullin was looking forward to seeing Kidd at age 39 still doing his thing at the Garden. “Jason is defying all kinds of logic,’’ Mullin said. “He sets a great tone, too, just by being an unselfish player. He throws the ball ahead of guys, gets them involved, makes them feel part of the team. It’s uncanny how he does it. He’s transformed into a 3-point shooter. “Wherever he goes, whatever stage of his career, he finds out what his team needs to win and he does it.’’ Mullin, who works for ESPN, was in Montreal on an NBA promotion during the preseason October night when Amar’e Stoudemire got hurt. Mullin wasn’t all that impressed. He told The Post then he felt Miami was in a different class. He backtracked yesterday, loving what the Knicks have become.
