The best way to avoid those run-down, leg-weary, out-of-breath, back-to-back NBA blues? Just take that second night off.
   
So the Jazz discovered Saturday, when they quit stifling their yawns, not to mention making their shots, about five minutes after tip-off. The Jazz got their rest, and once the requisite number of TV timeouts were taken, the Mavericks had their punch-the-clock 101-77 victory in American Airlines Center.
   
When the Jazz wake up this morning -- well, unless they sleep in -- they will find themselves in seventh place in the Western Conference, looking up at the Lakers.
