Don't NFHS rules tell us to ignore the violation in the situation where Team A is on a fast break, and a Team B player, runs out of bounds...yelling for a "leaving the court for an unauthorized reason" violation, to stop the play?
To stop the play would be to put Team A at a disadvantage. I believe you let the play continue.

If team A tries a long pass to initiate a breakaway, Team B intentionally kicks it, but it goes directly to team A for a layup, would you call the violation, and take away the basket?

I think these may be cases that are up in the air, if you take a very literal interpretation of the rules.

apples to oranges FrankH

besides i love that case play for the [yelling for a "leaving the court for an unauthorized reason"]

I can just see little Johnny screaming and jumping up and down with his arms waving trying to get our attention while he is YELLING "REFREE SIR I JUST LEFT THE COURT FOR AN UNAUTHORIZED REASON PLEASE WHISTLE ME FOR THIS EGRIGIOUS INFRACTION OF THE RULES."
yeah thats going to happen just like that

because every time i have made this call the players always look at me and say "oh you are right - i am so sorry for leaving the court for an unauthorized reason."

seriously where and how did they come up with this??

Conversation with a coach from a game Saturday during a TO:

Coach: That's the third time this half you've called palming on my PG (who also happens to be the coach's son).
Me: Ball is clearly coming to rest in his hand, coach. Aren't you seeing it, too?
Coach: Yahbut (note: he is actually agreeing with me that his son is palming the ball), no one's guarding him or even close to him. How do you judge disadvantage in those situations?
Me: The disadvantage is, if I don't make the call, the other team doesn't get the ball...that puts them at a disadvantage. I'll give you the same consideration when the other team violates.
Coach: (smiles and walks back to bench)

Maybe not relevent to the post, but a rare instance of a coach going "Yahbut." :D
