 Initiating Contact/Targeting an Opponent
 ARTICLE 3. a. No player shall initiate contact and target an opponent with the crown (top) of his helmet. When in question, it is a foul.
 b. No player shall initiate contact and target a defenseless opponent above the shoulders. When in question, it is a foul. (Refer to Points of Emphasis on FR-9 for a description of “Defenseless Player.”)
 PENALTY (a-b)—Personal foul. 15 yards from the basic spot, or 15 yards from the succeeding spot for dead-ball fouls. Also, automatic first down for fouls by Team B if not in conflict with other rules.
 官方对Defenseless Player的定义:
 • The quarterback moving down the line of scrimmage who has handed or pitched the ball to a teammate, and then makes no attempt to participate further in the play;
 • The kicker who is in the act of kicking the ball, or who has not had a reasonable length of time to regain his balance after the kick;
 • The passer who is in the act of throwing the ball, or who has not had a reasonable length of time to participate in the play again after releasing the ball;
 • The pass receiver whose concentration is on the ball;
 • The pass receiver who has clearly relaxed when the pass is no longer catchable;
 • The kick receiver whose attention is on the downward flight of the ball;
 • The kick receiver who has just touched the ball;
 • The player who has relaxed once the ball has become dead; and
 • The player who is obviously out of the play.
