Over The Back

[BktBallRef]

An official shouldn't say, "Reaching," just as an official shouldn't say "Over the back!" The terms do not exist in the basketball rule book.

It's not necessary to say anything. Simply give the signal that corresponds to the foul.

Call the foul:

Whistle and raise fist to recognize foul.
Bird dog if you want to, I don't.
Tell your partner who the foul is on, who the shooter is, if there is a shooter or where the spot is for the throw-in.

Report to the table:
"Blue, 4-4!"
Give signal. No verbalization is necessary.
Indicate number of shots if necessary.

That's all.
