How is the game affected if a ball is snapped before a play is called?

When a ball is snapped before a play is officially called, it results in a legal snap only if the offense was prepared and ready to play at that moment. According to NFHS rules, the snap must occur after the referee has signaled to begin the play. If the offense is in position and not caught off-guard, the snap is deemed legal.

In contrast, if the snap happens before teams are set or before the play is called by the quarterback or coach, it could lead to a penalty or violation depending on the specific circumstances. For instance, if the snap occurred after the quarterback was charged with a timeout or after a huddle when the team wasn't ready, it would lead to a foul or even a violation of game rules, resulting in consequences according to the NFHS regulations.

Thus, understanding the context of readiness is crucial when determining the legality of a snap. This context clarifies why a snap could potentially be seen as legal under certain conditions.
