If it ain’t broke, don’t fix it. Or, apparently, experiment with fixing it at a lower level of play.
That’s the approach the NBA is currently taking with free throws, as they’re experimenting with a new rule that will be implemented in the G League. For 2019-20, all players who are fouled in the act of shooting will shoot only one free throw.
If it’s an and-one situation, that one free throw counts as one point, same as always. If they’re fouled shooting a two-point shot, the free throw counts as two points. If they’re fouled shooting a three-pointer, it counts as three points.
