Question about more unwritten rules...

[justacoach]

"During the game they had an "illegal screen" call and used the player control signal; they were in the bonus but did not shoot free throws. They realized their mistake too late for the correctable error."

Pray tell, what was the exact mechanic?? Hand behind head or punch?
What makes you think FTs are warranted in this situation?

Seems like you are nearly as confused as they were.......
