First they got rid of proper defense by calling everything a foul, players would be going to free throw line 10+ times a game, and that is why we are losing real good defensive schemes, we still have some few defensive specialists, but overall defense seems worse. Then Curry came out, which was awesome individually, he is great for the basketball world, he did made even little kids watch it, and that's a big deal considering their attention span is as long as a tiktok video, so getting their attention was awesome. But then everyone else started to play like Curry, everyone was shooting threes, for a while we had teams just taking turns shooting threes. Now even Lebron is taking halfwary court shots, that is not really what we want to watch is it?
I agree with you that the silly play-in games and NBA tournament aren’t a cause for the decline in viewership, but a knee jerk reaction for trying to get it back. I too am sick of all the fouls. Seems to have started with the legalization of the gather dribble and James Harden step back along with the hand checking rules, etc. The crazy part is they did these rule changes to keep players from getting injured, and we’re seeing more injuries than ever.
I guess fans just get tired with their soft decisions given to players and they implement rules that is unacceptable to the fans since it makes the game became not attractive to watch anymore.
Same crazy shit happen to Edward on post game interview where NBA fined him a whooping $25,000 for saying bad words which I think just an expression and result of intense game which currently on https://www.mensjournal.com/news/nba-anthony-edwards-fine NBA could let that incident pass, But they didn't do it and still give penalty to Edwards for that nonsense reason.
Those games In game tournament and NBA cup is just a filler since maybe they want to give impression to people that competition in NBA became so tight and they want to make people feel excited about it. If they let the play rolled out the same on 90's or early 20's era then maybe all people would agree that each game in NBA is fun to watch.
