New York Knicks star Jason Kidd does NOT believe his drunk driving case in New York will have any affect on his performance in the upcoming NBA season … at least that’s what he told us on the way into court this morning.  A well-dressed Kidd — along with his legal team — rolled in to the Southampton Town Justice Court to handle business related to his July 15 arrest … when cops say he drunkenly slammed his 2010 Cadillac Escalade into a telephone poll around 2 AM.  Kidd had already entered a not guilty plea in the case.  Jason was also asked if he had anything to say to his young fans — but that question was met with pure silence.
