a) eventhough he does have a point about the parity, I highly doubt the NBA will contract with enough places wanting a team (Las Vegas, St Louis, Anaheim, San Diego and probably OK City if they do go back to NO if it's ever rebuild properly)
b) very funny that he mentions 27 teams, which is an uneven number which led to several problems (among others the dividing factors about a team being eastern or western conference)
c) if a contraction would happen, the NBA will probably look at type of ownership and avg attendance records. Truth be told, in this scenario atl will be seriously looked at, but can we be faulted for not blindly supporting an inferior product?
d) envelopes were done away with due to conspiracy rumors (frozen envelop Ewing). No way that this returns. I would be interesting to redo the odds for the lottery but the same for all will not happen. Perhaps even give very infinite small odds to the playoff teams, wouldn't that be fun?
e) shortening the regular season would mean a too big of a revenue miss, not going to happen
f) Entertaining-as-Hell Tournament, sounds nice, would be fun, not going to happen. Heck I think his best idea yet was to include a game of h-o-r-s-e in the allstar game but an Entertaining-as-Hell Tournament seems just to damn unlikely (for instance, if you are mathematically eliminated from a top 6 seed, you might as well tank for a better possible lottery odds AND to have fresher legs in the Entertaining-as-Hell Tournament.
