Both of these teams are not very good as evidenced by their respective records. However, both of these teams have been playing some better basketball since the trade deadline. For the Pistons, it was a complete roster overhaul at the trade deadline. For the Hornets, it was a couple of trades of veterans with an eye towards the future.
Neither team has won a ton of games since the deadline, but the on-court product has been a bit less hard on the eyes, which is basically all you can ask for during a bad season that you are just waiting to come to an end.
