Eliminating tanking would help the league, no more "process". The Celtics proposed a system where a rotation of draft picks would let each team know for certain its draft order forever. Every team would get the #1 pick sometime. once every 5-7 years, every team would have a top 5 pick. Trades would be easier to negotiate and teams that make poor picks wouldn't get multiple chances at high picks by stinking.
Eliminate the need for agents entirely. Give each team 15 slots of salary, say 5 starter salaries: all the same amount, 5 bench salaries, 3 end of the bench salaries, 2 two way salaries. The slots are flexible for the team: a player can be cut, but still paid and the team can offer the open slot at full salary to any free agent (or move a current player to a higher spot and fill a lower spot. If a cut player signs with a new team, the old team only pays the difference if the cut player goes in a lower slot. All teams have the same budget all the time and bad luck like a player being injured for a year will not affect a team as much. Get rid of the tampering nonsense and just let teams and players talk as much as they want about where they want to play and who they would like to play with.
Teams would have no reason to lose. Players would be attracted by fit and team culture, and a bit by location. A team might still decide to rebuild with a youth movement, but it need not be so extreme.
And third: the players association should be in charge of hiring, training, and evaluating the performance of the refs. The job of the refs should be to make the game safe and fair. Maybe players like Jaylen Brown and Zion Williamson will have longer careers. It seems to me that Jaylen is smashed in the face at least 5 times a game with no foul calls. Giannis speared Rob Williams in the chest on a drive with an elbow and wasn't even called for a foul. Why? Because he is a star and Williams is not.
Of course, the NBA will never accept any of these simple changes. The NBA is less a sport now and more of an entertainment business based on star worship and elements of gambling. The refs have only a little more integrity than the World Wrestling Federation the way the games are called now.
