*history lesson*
The Jazz are from Utah for the same reason that the Lakers are from Los Angeles. They moved from a city where the name made sense. The Jazz from New Orleans, and the Lakers from Minneanapolis, MN. Ironicly, the brand new residents of New Orleans (for basketball at least), are called the Hornets. There are not hornets in New Orleans.
I have said for a long time that basketball teams should have to leave their name behind when they move if it is only geografically suited to their former home.
