With a 54-win season in the books, an Atlantic Division crown and the No. 2 seed in the Eastern Conference, it might seem appropriate for Knicks general manager Glen Grunwald to take a bow. But when the door opens at Knicks practice, as staffers hold the media back on one side of the gym, Grunwald glances over and safely exits out the door into the team offices without a word. If it seems to resemble a "Wizard of Oz" feel with Grunwald the mystery man behind the curtain and the Knicks’ odd troop of front-office workers filling the roles of the wicked witch and the flying monkeys, hiding him from sight, it belies the truth: Grunwald is a nice guy who has done a masterful job this year. "Glen is a great guy and very well-respected throughout the league," an Eastern Conference executive said. "Every team has their own way of doing things. The Knicks, they do things a little differently." That different approach has meant that Grunwald is a ghost in New York. Yankees general manager Brian Cashman scales towers and jumps from planes for charity when not holding court as the face of the franchise. Billy King has the Nets as one of the most open and transparent teams in the NBA. Grunwald has spoken to the media twice this season — at media day to open camp and in a conference call after the trade deadline when he was greeted by one reporter with, "Is this really you, Glen?"
