Why? We are what, 30 games into the season and we already know 7 of the 8 teams who will be in the playoffs for the West. Why play all these meaningless games? Why not just lower the game, play teh same season length, so players can actually be healthy for the playoffs?
Because the NBA would lose money. It's a pointless suggestion. It's like sending the NBA a letter titled "A way to lose 1/3rd of your revenue right away". I already explained why extending the season is better. The question is what is the advantage of a shortened season over an extended one?
