You are right to point out what seems to be a paradox but I'm referring to FIBA to illustrate it is doable and don't transform defenders into cones. Now I'm not in favor of 4 quarters of 10, of 3 pts line closer, of smaller basketball court or even goaltending. I just think the unsportsmanlike foul rule used in FIBA could be a good option to reduce the number of FTAs and improve the flow of a game already sliced by one big half time and 8 long time outs, no need to add 2/3 min of hack a, 10 FTAs to prevent easy lay ups and again some FTAs at the end of the game when a team foul off the ball.
Not a big deal, just a suggestion worth imo to experiment
