Where is the throw in after the second of
 

two free throws is missed by an air ball? Ordinary personal foul, no techs or flagrant, HS rules. Is it end line of FT line extended?

End line; spot throw in

Yes. It is.

I think the OP is asking if the throw in, if the final free throw completely misses the rim/backboard, is at the end of the free throw line prolongated. IOW on the sideline. He's asking if the free throw line is the POI.

At least I think that is what he's asking.

Look at the throw-in chart, the circle, above the free throw line is part of the lane, so any violation from that spot goes to the endline. So even if you applied POI, which it isn't, it would still be an endline throw-in.

Also be sure to note that if the ball hits only the backboard you still have a violation. The FT try needs to hit the rim or enter the basket to avoid a violation. Futhermore, as has been noted this violation would result in a spot throw-in from the baseline, lane-line extended. Assuming the FT shooter is standing at the mid-point of the FT line, I usually administer the throw-in on the lane-line extended closest to where I am. I would imagine though that if a shooter took his position on the far right or left side of the FT line, I would administer at the spot closest to where the FT was released.

What if the coach said "Could I have the spot on the other side?":D

Always take it out on table side since on free throw, that is where the administering official is located.

if the coach asks then just walk over to the other endline and administer the throw in...as long as he asks nicely of course.

He does not have a choice. The officials determine the spots. ;)

Peace

I agree with jrut. Table side throw in, your already there. If a coach wants a certain spot to run a play, I'm sorry that's kind of silly. If he's that concerned he should draw up plays for both sides.

If it was 3-man, he wouldnt even have that choice!:D

Once the ball hits the backboard...is it OK for the players along the lane to move into the lane...or do they have to wait for the ball to hit the rim?
(learning tool);)

technically the rule says rim -- but use some judgement here please

You're going to allow the other team to get their throw-in under their own basket? On the other endline? ;) (Sorry, couldn't help myself!)
