Practices, as you might expect when a team returns after losing five straight on the road, were crisp, competitive, almost upbeat on Tuesday night and Wednesday.
  But the overall attitude of the Pistons remains the same -- somewhere between disappointed and angry.
  "If you really look at things from the start of the year and said, 14-11, I don't think too many people would be upset about that," Jon Barry said. "But obviously we are, given the situation we had put ourselves in with a 14-6 record. That's what's so disappointing. To regress the way we did. I mean, out of 10 halves we only played good in about four."
  The fact that the Pistons play two of their next three games at home -- against the Nets tonight and the Heat on Sunday -- where they are 8-2, provided little solace.
  "That doesn't mean we can just show up and say we have a magical fix just because we are home," Barry said. "We have to come out and play. We have a lot of patchwork to do. We were terrible."
  The emphasis the last couple days has been on regaining the edge -- call it intensity, aggression, hustle -- the Pistons had earlier this season, particularly on defense.
