Point of emphasis for officials: "Here is the statement straight from the NFL’s competition committee report: "Prior to a snap, any quick, abrupt movement by an offensive player, or several offensive players in unison, which simulates the start of a snap, is a foul. These acts include (a) a quarterback in shotgun formation thrusting his hands forward in an exaggerated manner when there is not a simultaneous snap, (b) abrupt movement of the ball by the center, (c) abrupt movement by the center's head or other body part, and (d) a quick abrupt shift by two or more players in unison.""
