The Jazz's six-game winning streak was a feel-good diversion. But their 12-game losing streak looks a lot more real.
   
After feasting on the likes of the Clippers and Bucks for two weeks, the Jazz moved up in class Saturday night and found themselves outclassed by a longtime tormentor. San Antonio, in a dogfight for the NBA's best record and top playoff seed, flicked the Jazz away with a 27-4 second-half romp, turning a close game into another Texas rout, 101-81 in the SBC Center.
