I'm open to ELAM ending, I don't think it'll ever happen but I think it's a positive change and I love that the NIT implemented it so you get to see how it changes fairly high level basketball.
I'm not sure how to change the rules of the game, but I'd love to see high level basketball played without a 3-point line just to see how the game changes. I don't want the three pointer removed in the pros, but I'd like to see how the game changes without it, where the mid-range jumper becomes the dominant style and how defenses have to adapt to it.
I don't think that the era of player mobility is good for the league or the sport. It's good for drama, it's good for twitter feuds, but it basically makes 26 teams irrelevant for the title. Every once in a while you get a team like Miami from two years ago who can make a serious run and hope to get lucky in the championship against a stacked team, but over 7 games it's hard for the stacked super squad to truly lose out. But also I don't know if that Miami squad makes the run outside of the bubble either, that season was such a unique one with the long delay and then quick wrap up. I get that player mobility era is good for players, they basically set their own salaries, take paycuts, dictate salaries in the league, and play where they want with who they want on contracts that basically don't exist, aren't binding, and they all get paid in some way. But it sucks for fan bases for about 26 cities in a given season.
I'd like to see the league cull back from 82 games to something like 58-60. Again, I know the league would not accept a revenue decrease. So mid-season I think there should be a 2-3 week break where you have a sort of all-star event, with a designed 1 on 1 tournament, and they seed the tournament in a way that makes really interesting matchups. WWE King of the Ring style, where you set it up so that Ja Morant and Zion WIlliamson have to play 1 on 1 in round 2, or Bol Bol vs. Tako Fall in round 1. Call your own fouls. An alternative would be an olympic-style 3 on 3 tournament of mixed teams/players, with the international 3-on-3 rules. They also have to incentivize players to play because teams won't want their stars to play in the tournament to avoid injuries, but imagine how sick it'd be to see Donovan Mitchel v Jamaal Murray, AD vs Giannis, Durant v Lebron... Even without a financial incentive I think players would take a 1 on 1 incredibly seriously against each other, especially if you call your own fouls. There could also be some good matchups WWE style where two teammates end up getting matched, Tatum vs Brown. This also really rewards the era of mobile sports betting. Live lines. Imagine if the final four was played in one night, 7PM you have game 1, 730 game 2, 8pm the championship. 90mins of basketball at a bar with live line betting, shit would get pretty serious.
3 on 3 international rules tournament. Teams are representative of ~16 NBA franchises or regions or something. Each team is made up of 5 players, 2 from the NBA team, and then 3 from the G-league with a rule that at least one G-league player has to be on the court at all times maybe with reserve players for injury reasons. I Think you'd get a lot of hungry g-leaguers looking to prove themselves.
I don't think these things improve the actual game. I'm not sure how you do that. The league has tried to fix the end of games. It's better than it was in the late 90s/early 2000s, they reduced the amount of timeouts you can take in a given period of time, added some changes to the foul calling system.
Would changing to a 5/7 system for fouls like college benefit play? It rewards "saving" those 2 fouls from 5-7 before the double bonus, gives the defense incentive to not foul after foul 4 until the end of the half to save those 2 fouls. But, again the 1 and 1 might be too much of a reward, and it could be the wrong incentive.
