Kinda random but I feel like this would fix a massive issue of late game fouls slowing the game to a crawl and would force defenses to be extra careful instead of playing borderline football because the refs are scared to call a foul to decide a game. It would be an intressting mix of teams wanting 3 point specialists on the court vs playing bigs to grab rebounds and play d since hacking them wouldn't be a problem anymore
This is the type of game where betting really helps to spice it up
