How does USSF look at referees whom do not give signals on throw-in, corner kicks and goal kicks but verbalize their decisions? As an AR, I mirrored what the referee was verbalizing but, I simply like to know the proper protocol.
USSF answer (April 30, 2007):
The point of signals is to let everyone involved in the game know what is happening (players, ARs, team officials, etc.), not just those within earshot. Just as with the advantage signal needing to be as public as blowing the whistle, simply verbalizing possession for a TI, GK, or CK (even if understood perfectly by the players in the immediate vicinity) may not be enough for others who need the same information but who are farther away. Unless one’s voice is sufficiently stentorian to be heard around the entire field, visual signals are needed.
