Glenn Rogers of the San Antonio Express News speculates that ex-Knicks coach Jeff Van Gundy won't be long in returning to the NBA's coaching ranks.  He believes it was not burnout that made him quit.  Rather, he thinks Van Gundy was displeased with Knicks management's refusal to allow him to interview for the Portland job and their refusal to sign him to an extension.  Rogers speculates Van Gundy will bring his hard-nosed defense to the Western Conference soon.
