There are alot of interesting ideas and alot of ones that need work. The biggest thing is that there is no really good idea that everyone can agree on.
I dont like the automatic home court in 1st round thing. No reason why the 25 win Hornets, Rockets or Wizards should get home court over a 50 win team who would have been 4th in the conference (Cavs were 4th in East last year with 51 wins). There is no reason for teams to even try the last 60 games on the season if they know they already have a playoff spot wrapped up.
The best idea yet would be a bump in wins for your season total (maybe 3-5 wins). This way you still have to try the rest of the season in order to move up in the standings, and you get rewarded for this NBA Cup win (At 3 wins, the Lakers last year would have went from 7th to 5th, or the Thunder would have been 7th and with 2 home play in games to get into the playoffs instead of 2 road games)
Lets give it a year and see how the teams treat it. People hated the play in idea and I think that has worked out fine.
