I would add the two Florida teams and Toronto.
I would contract the Clippers and the Oklahoma Thunder and create 4 divisions with six or seven teams each:
So in the Eastern Conference:
NorthEast - Boston, New York, New Jersey, Philadelphia, Toronto, Washington
Southeast - Miami, Orlando, New Orleans, Houston, San Antonio, Dallas, Atlanta
Midwest - Indiana, Cleveland, Detriot, Chicago, Milwaukee, Minnesota
West - Portland, Utah, Phoenix, Denver, Los Angelos, Golden State, Sacremento
If I had to cross off two more teams, it might be Miami and Sacremento to make the divisions even. The draft dispersal might look like:
1. Dewayne Wade
2. Micheal Beasley
3. Kevin Durant
4. Rudy Gay
5. Micheal Conley
6. Chris Kaman
7. Jeff Green
8. thru 20. the Starting Veterans like Marion, Baron Davis, Chris Wilcox
When it comes to Boston's turn, I suppose they can make Antione Walker an overpaid mascot or a waterboy.
