"On the floor"

[jdccpa]

I attended an IAABO camp this summer.

IAABO's feeling was that too many unapproved signals were creeping into the game at all levels. They insisted on us using only proper mechanics and approved signals.

We were told not say such things as "on the floor" or "before the shot" and never ever put up one or two fingers immediately after blowing your whistle.
It was: be poised, under control and businesslike.

And no need to "sell" calls by doing such things as hopping across the court while "signaling" the block foul call.

It was: whistle (immediately spit out the whistle),fist straight up and high, color, number, prelim foul signal, tell partner who is shooting and how many or where ball is coming in from....hustle to reporting area, stop, gather your thoughs and report.
