nit picking calls-violations

[Nevadaref]

Does the kid run in for the rebound? How soon can you tell whether or not this player will get the rebound?
If not part of the play, then I would strongly suggest to let it go.
I fall into the advantage/disadvantage category.

I had a personal experience with this call last season.
In a 3-man crew, I had a partner call this "violation" from the C, while I was T, on the defense during the first shot of a one-and-one with the shooter's team leading by one with 34 seconds remaining in the 4th quarter.
The defender did not even move from the top of the key to attempt to rebound.
Of course, the shooter made the substitute throw.
It created a bad situation.
The coach went nuts, after the game a fan chased us down a hallway to a lockerroom telling us how good he thought we were, and a video tape of the game was sent to the league office.
All over a toe on a line which was about twenty feet from where the rebound was being contested.
