Klay Thompson walked off the elevator on the fifth floor of the Sheraton Times Square Hotel wearing a white-collared shirt with thin red checkers, dark denim jeans and a tired face. Golden State's dynamic shooting guard had played the night before in Minnesota, taken a flight to New York and then gone out for pepperoni pizza in midtown Manhattan, which kept him up past 5 a.m. ''I immediately regretted that decision,'' Thompson quipped as he strolled through the hotel to begin the frenzied NBA TV Media Circuit on Thursday. After a few hours of rest, Thompson meets with NBA officials to begin the media gauntlet.
