Great thread except for the sexism debate. Lots of fun ideas and I can't wait to post mine so here goes:
1. Go back to the old lottery system. The team with the best record gets one ping pong ball and the team with the worst record gets 14 ping pong balls, second worst gets 13, etc. This lottery should happen right in front of everyone on live TV.
2. Decrease fines and suspensions for fighting. I hate the rule where you get suspended for leaving the bench. I want to see fights in the league again without 20 game suspensions. Let's face it, the Malice at the Palace was pretty fun to watch and no one really got all that hurt. On this note, I would also like to see fights and technicals on NBA2K13 please. They have injuries. Why not fights or at least technical/flagrant fouls?
3. Eliminate the salary cap completely. And remove any age restriction. If the Wolves want to sign Jabari Parker to a 5 year, $200 million contract this summer, they should be able to and Jabari should be able to sign such a contract. I hate the age restriction. If a 16 year old is good enough to earn millions doing what he is best at, he should be able to. A lot of these people are poor and will never make much money doing something else. They should be allowed to earn their market value. I'm all for the players getting what they're worth. I also like the idea of Paul Allen being able to buy a contender to play in Portland.
3. Make the division title mean something again. Every team plays five games against each of their division rivals. I miss the old days of playing a 5 game regular season series against the Lakers. And on that note, I'd like the four division system again. It would mean less games against the rest of the conference and Eastern Confence teams but that's fine by me. Division winners get top 2 seeds. Like the old days.
4. Have a Play-in single elimination tournament for the 8th seed. 15th plays plays 8th place, 14th/9th, 13th/10th, 12th/11th, etc etc. Three day tournament in a three day period between regular season and playoffs. No days off for play in teams. Every team can win the championship. If you're the 15th place team and get the 8th seed, though, you are not in the lottery. Only the non-playoff teams are in the lottery as usual.
5. Have big cash prizes for the dunk, three point, and skills contests during All Star weekend. Maybe we could LeBron and Kobe to face off in the dunk contest if there was $5 million on the line. Also, add a 1 on 1 tournament.
6. The winning conference of the All Star game gets home court advantage in the NBA Finals.
