American Football Rules IFAF Approved Ruling 7-1-2:IV
IV. Team A is in a no-huddle offense and is moving to the line when the ball is made ready for play.
Although some players settle into their positions and stop, at least one player never stops and is still moving when the ball is snapped. RULING: Dead-ball foul — Illegal shift that converts to a false start. Team A never satisfied the one-second rule before the snap. Officials should shut the play down and penalise Team A five yards.
