I see no issue with re-organizing the divisions BTW and sure the Atlantic is easy right now, but there was a time when the C's and Sixers were by far the two best teams in the conference. That stuff comes and goes.
I guess if you were going to re-draw the divisions you would do something like this though it isn't as easy as one would guess because of the grouping in the mid-west
1 - Boston, NY, Brooklyn, Philly, Washington
2 - Chicago, Indy, Detroit, Cleveland, Toronto
3 - Miami, Orlando, Memphis, Atlanta, Charlotte
4 - LA, LA, Sacramento, GS, Portland
5 - Dallas, NO, Houston, San An, OKC
6 - Phoenix, Den, Utah, Minny, Milwaukee
This one might also work
1 - Boston, NY, Brooklyn, Philly, Toronto
2 - Chicago, Minny, Milwaukee, Detroit, Cleveland
3 - Memphis, Atlanta, Charlotte, Washington, Indy
4 - LA, LA, Sacramento, GS, Portland
5 - NO, Houston, San An, Miami, Orlando
6 - Phoenix, Den, Utah, Dallas, OKC
