Editing Snap (gridiron football) (section)

==Snap count==
{{unreferenced section|date=October 2012}}
The team entitled to snap the ball will usually know in advance the moment when the snap is to occur as one of their players calls out signals, which usually include a loud sound such as "hut" voiced one or more times, the number of which they know; they are thus said to know the "snap count".  Therefore, they have a considerable advantage over their opponents. The center is not, however, allowed to make motions simulating part of the snap-action; therefore their opponents can be confident the first motion of the ball or the center's hands is the beginning of the snap.

The snap count is decided on in the [[huddle]], usually expressed as "...on <number>." being the final words spoken by the quarterback after calling the play but before the huddle breaks and the players go to the [[line of scrimmage]].  The snap count allows offensive players to have a small head start.  The defensive players want to predict the snap, and build up speed such that they cross the [[line of scrimmage]] exactly as the play begins, to increase their chances of getting a tackle for a loss or a sack. By varying the snap count, a quarterback forces the defensive players to react to the movement of the offensive players, or risk being called for an [[Offside (American football)|offsides]] or [[Encroachment (gridiron football)|encroachment]] penalty. Unfortunately for the offense, this advantage can sometimes become a disadvantage. When faced with an exceptionally loud stadium, players may be unable to hear the snap count and are forced to concentrate more on visual cues (silent snap count or a [[Hard count (American football)|hard count]]), or risk [[false start]] penalties.

The offense must also be mindful of the [[play clock]]. If they fail to snap the ball in time they incur a delay of game penalty.  Also, with a dwindling play clock, the defense has better chances of guessing when the ball will be snapped.  It is easier to predict when the ball will be snapped with 2 seconds left on the play clock, rather than 5 seconds.

The defensive team is not allowed to simulate, by calling out numbers, the offense's snap count. Successfully simulating the count would cause members of the offensive team to act too early ruining co-ordination of the play and inviting penalties. Current rules, unlike earlier rules, position officials so far from the line of scrimmage for 50 minutes of the 60-minute game that it is extremely difficult to hear if the defense is simulating the count.
