If I was in charge of the NBA, I would

reinstitute the "3 chances to make 2" free throws once the limit of 7 fouls in a half has been reached in by the opposing team. This would also apply to shooting fouls. For fouls on three point attempts, 4 chances to make 3 would be applied. In addition, I would eliminate "fouling out." A player could accumulate unlimited fouls during a game.
