The NBA didn't like that everyone figured out that the Oklahoma City team name is the Thunder, so they went and registered 5 other names: Barons, Bison, Energy, Marshalls and Wind.
Barons is OK, if not sympathetic in tough economic times.
Bison is regionally appropriate, but lame.
Energy is trendy, but falls flat. ("Alternative Energy" would have been awesome.)
Wind is the worst name I have ever heard for a major pro sports team.
As for Marshalls? Let's hope the AP simply had a typo, because otherwise, the NBA registered a misspelling. It would be "Marshals," if they meant like the old lawmen of the Dust Bowl. "Marshalls" would be if they were naming the team after a famous Supreme Court Chief Justice or a down-market department store.
