I can't take credit for this its in the Georgia officials manual but it is good. These are presnap responsibilities.


1. During a conventional offensive huddle:
a. Spot the ball. Move to your pre-snap position while maintaining your eye contact on the ball.
b. If “no huddle” offense, stay on ball until the Referee signals you to move to your pre-snap position prior to the Referee’s “ready for play” whistle. The Referee will withhold his “ready for play” until you are in position.
c. Assist the Referee with whether the clock starts on the snap or “ready”.
d. Count offense after the ready for play signal – check-off with the Referee with “thumbs up” signal if 11 or fewer players. Try to time your signal with the signal given by the Referee.
e. If after the ready for play signal there are 12 or more players, and no player is attempting to leave the field, then throw your flag for substitution infraction and stop the clock.
f. Remember to adjust your down indicator. Also remember to adjust your ball position indicator. In order to remind you of the ball position in relation to the hash marks, this indicator is very helpful in keeping track of previous spots on incomplete passes and accepted penalty enforcement.
2. Pre Snap:
Position – 6 to 9 yards off the ball, shaded to the opposite side of the center from the Referee.
a. Keep the snap in view.
b. Vary your position to keep offense from using you as a “pick”.
c. Count the offense if unable to in huddle.
d. Verify you have 5 players 50-79 on the offensive line.
e. Know ineligible receivers by number or position. Recognition of covered tight end requires knowledge of auxiliary signals by either Head Linesman or Line Judge. Identify unbalanced line if it exists.
f. Be aware of clock.
g. Know what defensive players are on the line of scrimmage (blocking below the waist).
h. Watch for:
• Snap infractions and false starts.
• Excessive quarterback head movements simulating action at the snap.
i. Listen for disconcerting signals by the defense.

3. At the Snap:
a. Key on the center (snapper) and the players on either side of the snapper (the guards). Other officials are primarily responsible for judging action on or by players outside this group of 3 players.
b. Read point of attack and be aware of free blocking zone.
c. Watch for:
• Holding, illegal use of hands and personal fouls.
• Chop blocks and other illegal blocks in the free blocking zone.
• Fumbles. Drop beanbag on or parallel to the spot.
