Just my opinion, but here's an option for alignment:
Atlantic: Philly, Boston, NY, NJ, Washington, Charlotte
Central: Miami, Orlando, Cleveland, Atlanta, Indiana, KC,
Midwest: Houston, Denver, San Antonio, Utah, Chicago, Minnesota,
Pacific: Seattle, Golden State, Portland, Phoenix, LA Clips, LA Lakers
This way, Orlando and Miami avoid playing in the Western conference (1st proposal has them in the Midwest) and those long flights :-)
