As bad as things are going right now for the Pistons -- and with seven straight losses, things are going mighty badly -- there is always somebody who has it worse.
  Take tonight's opponent, for example. The once-proud and powerful Miami Heat come limping into The Palace with the second-worst record in the NBA, and riding a five-game losing streak.
  "It's not working, that's all there is to it," said Heat Coach Pat Riley after his team lost to the Memphis Grizzlies at home Friday. "We are just fumbling and stumbling around."
