THE NBA season doesn't tip off till Oct. 30, but two of its brightest young stars were all over TV last weekend. LeBron James followed Michael Jordan and Peyton Manning in hosting Saturday Night Live. One highlight was a sketch in which he played a Solid Gold dancer (left), but LeBron tended to look stiff and seemed to stare holes through the teleprompter. A more relaxed Carmelo Anthony went live the night before, shilling for mStation, an iPod speaker company he invests in, on QVC (right). His big thrill? Meeting Joan Rivers backstage.
