Not immediately after the ball touches the backboard. Think back to your high school geometry, trigonometry, and physics classes. Now think of a typical high school layup. Ball is often released from under the ring (especially in girls high school games and most middle school games) and is moving upward after the release, it then hits the backboard, bounces (reflects) off the backboard at same angle of the incident angle, still with some upward momentum, and then continues to move upward until the force of gravity takes over and pulls it back down into the basket.

Law of Reflection happens on a pool table all the time.

For rules purposes, it is considered on its downward flight. It is not meant actually be seen that way. And the rule also states that if any part of the ball is above the ring, which is the case if the ball touches the backboard in almost every case. So it is just a different rule and the ball hitting the backboard is considered off-limits and has a chance to go in as well.

I kind of understand the NCAA goaltending/backboard rule (thanks anyway for the NCAA explanation), but I was 100% talking about the NFHS (high school) rule with ilyazhito.

In it's full context, ilyazhito was advocating automatically making blocking a ball off the backboard goaltending in high school (as in college), implying that balls in this situation were probably mostly on their downward flight anyway, and I replied with a scientific/mathematical rebuttal to a part of his post.

Again, it depends on the angle of the shots. If a jump shot or set shot (many free throw attempts are set shots) hits the backboard, it will go down. Some layup attempts will go down as well, especially from boys who are able to jump and release the ball above the rim level. In these cases, the ball will be on its downward flight from the backboard. Changing the rule to make all balls of the backboard be considered as on their downward flight would simplify goaltending enforcement.

Because by the trajectory, it's already on it's way down.

Are youall just trying to appease the fans when they wonder/shout why a goaltending is not made in a HS game? Is that why you all are advocates of switching to the NCAA stance on goaltending? When will the compromising stop? Lol

Oh and a final

Fans do not come into the play for me about this rule. What I would like is some level of standardization, but I think the NCAA rule is harder at that level because there is much more above-the-rim play. At least it is a line of demarcation as opposed to some other stance on what be a total judgment call. That is why I said I am not necessarily a fan of that rule change to the NCAA level. I was not a fan of the rule change at the NCAA level either when it happened, but we are here. Not changing back.

Peace

I'm trying to provide for a consistent guideline for goaltending enforcement. Having balls of the backboard being considered on their downward flight, or changing the rule to read "a try in flight, with a chance of scoring, on its downdward flight or off the backboard" would allow for more consistent enforcement of the goaltending rules.

Let's be serious and keep in mind who plays games under NFHS rules? Interscholastic teams, including girls high school teams, and middle school teams of both genders. Thousands of games. Tens of thousand of players. What percentage of layup attempts in these games are immediately on the way down after the release and then immediately "reflecting" downward off the backboard?
