Parity is easy.
1. Shrink by 4 teams.
2. Share revenue.
3. Fine flopping with playoff games. LeBron would lose 4-5 more games every season.
I'm not a socialist...except for sports. I like revenue sharing. I think teams can keep "their" money (tickets, jerseys, anything that ONLY has their name attached to it), but "shared" revenue (mainly tv revenue) needs to be shared. LA can't exist without Utah. They need someone to play. That way big markets still have some advantage with money (charge more for seats, put their players on billboards, ads, etc) but smaller markets still have a chance.
I think contraction needs to happen. There are too many teams out there right now.
Like I said, contract 2 teams (4 would be ideal). Don't barter, argue, pull out of a hat. Look at the bottom 4 profitable teams the last 10 years. Bang, gone. Then, revenue share any dollar that has more than one team attached to it. Equally. Third, I really like the fixed draft order. You can then plan for future knowing where you will be and what you need to get to.
Also, people are worried about NY having a #1 pick, but with their buying power, I would put money down that they would have traded that thing long before they pick with it. Teams with money are stupid with their other assets. They feel they can buy their way out of problems and they don't value picks.
Also, this would make picks a lot more valuable this way. You could demand more for your picks. Can you imagine if the Lakers came to Utah and said, we have the #3 pick in 2017, we want to trade that for Hayward. Boom. You could do it.
As far as people delaying entering the draft, yeah, sure it could happen. Just like how Barnes delayed coming into the draft when he was thought of as a top 3 player. It already happens now-a-days. And, in the NBA, only one player has been good enough to demand where he wanted to go (Kobe). And in the NFL, only two players have pulled that off (Elway and Manning). I just don't think it is as big of a deal as people make it out to be. AND, let's say Wiggins didn't want to be in Utah and Utah had the #1 pick. The fixed draft protects Utah, because now they can make a trade and KNOW what they are getting back for it.
You want Wiggins? Sure, I want two top 5 picks (a #1 and another one) and this player. Instead of protected picks and what happens if the team is great, etc, etc, etc.
