Raymond, my apologies. I only have so much energy and I don't want to waste it on your hypothetical scenario. The short answer is if there is a foul, I will know it (a defender lying on the floor and sticking out a leg to trip or reaching an arm out to grab). There was none of this in my original situation.

LGP is perhaps the most overrated term in the books. I've said it for many years. This thread, I think, backs me up on it.

You continue to prove that it is in the sand by continuing to insist that the ruling is somehow related to LGP. In doing so, you continue to expose that you have no idea when LGP applies and doesn't apply. Keep denying simply concepts that are laid out in plain black & white. Your credibility shrinks with each post.

Enough energy wasted on a lost cause, I'm out. I'll spend my efforts on people that actually want to learn.

try using logic and extrapolate from these examples in the casebook:

B1 slips to the floor in the free-throw lane. A1 (with his back to B1,
who is prone) receives a pass, turns and, in his attempt to drive to the basket,
trips and falls over B1.
RULING: Foul on B1, who is not in a legal guarding position.

Me: why is it necessary to mention that B1 is not in LGP if it doesn't matter? Because it does matter.

A.R. 101. Player A1 attempts a shot, which bounces off the rim.
1. Player A2, who is in the lane area, grabs an offensive rebound and
immediately attempts a put back and crashes into the torso of B2, who is
grounded on the court within the restricted area; or
2. Player A2, who is located on the wing just inside the three-point line,
gains possession of a long rebound and immediately drives to the basket
with no defender. Player A2 crashes into the torso of B2, who is grounded
on the court within the restricted area.
RULING 1: When A2 rebounds the ball and immediately makes a
move to the basket, there is no secondary defender and the restricted
area rule is not in effect.
2: When B2 has established and maintained a legal guarding position
and illegal contact occurs, it is player-control/charging foul on A2.
(Rule 4-36.3, 4-31 and 10-1.14

Me: Why point out that B2 has established and maintained LGP if it doesn't matter? Because it does matter.

This is all in the same books that say this:

Every player shall be entitled to a spot on the playing court, provided
that such player gets there first without illegally contacting an opponent.

We are discussing NFHS rules not NCAA which we know has a different ruling for this play

Nothing ...
 

It doesn't matter here:

10.7.1 SITUATION A: B1 takes a certain spot on the court
before A1 jumps in the air to catch a pass: (a) A1 lands on B1;
or (b) B1 moves to a new spot while A1 is airborne. A1 lands
on one foot and then charges into B1. RULING: In (a) and
(b), the foul is on A1. (4-23-5d)

Nothing about B1 initially having both feet touching the playing court.

Nothing about the front of the B1's torso facing A1.

Nothing at all about initial legal guarding position.

Nothing, and yet the NFHS confidently rules this a charge on A1.

Legal guarding position does not matter in NFHS plays like this.

Nah, you guys are overthinking it. This is in the NCAA casebook. They probably figure people will use common sense and not spell out every little thing. These books are written by human beings lol:

A.R. 87. B1 takes a spot on the playing court before A1 jumps to catch a pass.
1. A1 returns to the playing court and lands on B1; or
2. B1 moves to a new spot while A1 is airborne. A1 comes to the floor on
one foot and then charges into B1.
RULING: In both (1) and (2), the foul shall be on A1. In (1), B1
is entitled to that spot on the floor provided he gets there legally
before the offensive player becomes airborne. However, in (2), when
A1 possesses the ball then lands on the floor, no time and distance is
required.

Me: again, this example is in the same book as the earlier example saying it was a block because the guy was on the floor, and thus not in LGP. So LGP is needed, just not spelled out, probably because no one in the history of the game would ever think that readers wouldn't already know that that is a given.

We arent overthinking it...this is a NFHS play and you're using NCAA rules.

Not to mention that he's still wrong under NCAA rules for everything else in this thread.

I'm merely pointing out that the college book has the same language as the NFHS book. My goodness lol. No one that has played or officiated at a high level would stomach a charge being called on a driver into the back of someone under the basket. ever. Puhleeze.

The NCAA-M has a casebook that covers it. The NFHS, maintaining a different approved ruling, does not. No one that has played or offiicated on an NFHS level would stomach a NCAA-M call being made on a play during a high school game. :)

I will.
And I'm in my right mind. (Not left-handed, even.)

For those (the one, only, perhaps) using LGP to defend his position on this NFHS ruling, the player getting run into/over/through IS NOT GUARDING ANYONE. S/he simply has the right to the spot on the floor at the time that s/he was run into/over/through. Legal guarding position has nothing to do with the discussion.
That's NFHS on it.
Easy! :)

I would not necessarily say all of that BM. Just because the words are not there does not mean that the words are not there. In other words, it may not say it, but it references rule 4-23-5d and that rule explicitly discusses obtaining legal position. Additionally, rule 4-23 mentions both feet touching the playing court, initial legal guarding position, etc. Now, that is not exactly what you wrote but I think you get my point. The case may not say things but rules that they reference might.

And not sure why Raymond is going on about someone on the floor setting a screen as screeners are vertical.

Vertical Plane ...
 

You may be correct here:

The screener must stay within his/her vertical plane with a stance approximately shoulder width apart.
