It'd make more sense for the NBA to go to 36 teams instead of 35-6 divisions of 6, and an even number of European teams for scheduling purposes.
Europe - Madrid, London, Berlin, Cologne, Moscow, Athens
Atlantic - Atlanta, Charlotte, Miami, Orlando, Philadelphia, Washington
Northeast - Cleveland, Detroit, Toronto, New York, New Jersey, Boston
Midwest - Chicago, Indiana, Milwaukee, Minnesota, New Orleans, Memphis
Pacific - Portland, Utah, LA Lakers, LA Clippers, Sacramento, Golden State
Southwest - Denver, Phoenix, San Antonio, Houston, Dallas, Oklahoma City
