Communication signal
Does anyone use a NFHS communication signal for LJ and HL when a ball carrier is running down the sideline? Was told to use punch signal, extended arm to indicate a player with ball is inbounds while running down sideline. If your association uses this communication signal (not referring to "last play was out of bounds" or "backward pass" or "player nearest wing is off line of scrimmage") then include the reasons why they are using such a signal and what is the main purpose.
