I've been meaning to post this for a while.
I found this video fascinating. It is an analysis of St. Joe's basketball offensive system, put into effect after the 2017-18 season, when its offensive efficiency was pretty average. The resulting system, with the same players, resulted in an explosion in efficiency.
I don't know if elements of this would work in the NBA, although I could see a creative coach like Brad stealing bits and pieces. The beauty of the system is that no one stands around, ever. Every movement from the ball handler results in a movement by the other 4, while maintaining great floor spacing.
Let me know what you think. The players on this team are D-3, obviously this is not NBA or D-1 level talent. But the beauty and the logic of the system is quite engaging. Basically no pick and rolls, no dribble hand offs. The best word I can use to describe it is choreography.
