The Knicks’ decision to fire GM Glen Grunwald just days before training camp has puzzled Knicks fans and players alike. Carmelo Anthony told the NY Post that he was “shocked” that the Knicks stripped Grunwald of his job after he retooled the club all summer: “Several league executives were genuinely shocked at the timing of the move, as was Carmelo Anthony. ‘I was shocked,’ Anthony said at a promotional event. ‘I never heard about it and nobody knew it was coming.’”
