If the Kings do indeed relocate to Seattle, it puts the NBA in a bit of a predicament. The current division alignment is already a bit... um... let's say interesting. Check the map.
Now if the Kings were to move to Seattle, that would essentially put a team in the Pacific division that is located north of a team in the Northwest division. Now that would be a complicated map. The quickest fix would seem to be moving the Sonics back to the Northwest division and moving Utah to the Pacific. Maybe someday they'll address that Memphis situation, too...
