I think all this discussion, triggered by the 44-minute "experimental" game the C's participated in, depends on how you define the problem. Is the season too long, or the games too long or just end of games too long? What is the problem we are trying to solve?
I think fundamentally the NBA ought to be focusing on developing a better entertainment product out on the floor, and that will keep fans coming back, watching on TV, and generally showing greater interest in the game. IMO the best way to do that is to make sure players get the proper rest between games and try to cut the sting of a sometimes brutal travel schedule.
At the same time, most people really don't want to change the basic rules and regulations because the game history would be shaken. So here is my proposal:
1. Cut back pre-season to five games.
2. Start the season mid-October.
3. No more than one back-to-back per month (7-8 total for season, not 14-18 as is now)
4. No more than 3 games in 5 nights
5. Cut back first round playoffs to best of five.
6. No changes in length of games, number of regular season games or any basic on-court rules
Players will be better rested and will perform better on the court. The pre-season is too long as is and players generally come to camp in better shape today as compared to years ago. Having only best of five in the first round moves the playoffs along a bit faster.
