Questions

This is the first-year take-home quiz, rebuilt from the two Word documents that used to live on the equipment page. Answer each one with the definition and its rule-section-article citation, the way the original asked for it — What is a foul? → 2-16-1, a rule infraction for which a penalty is prescribed.

1. The two pieces of equipment you will look at all night

What are the line-to-gain and down indicators, who supplies them, and where on the field are they operated?

2. Shift

What is a shift, and what must the offense do after one?

3. Live ball

When does a ball become live?

4. Dead ball

What is a dead ball?

5. False start

What is a false start? Give all three ways it can happen. What happens if the false start causes the defense to encroach?

6. Down

What is a down, when does it end, and what does "loss of down" actually cost a team?

7. Fumble

What is a fumble?

8. Muff

What is a muff, and why does the difference between a fumble and a muff matter?

9. Neutral zone

What is the neutral zone on a scrimmage down, and what is it on a free-kick down? When is it established?

10. Encroachment

What is encroachment, and over what interval can it occur?

11. How many on the line

How many Team A players must be on their line of scrimmage at the snap, and how many may be backs?

Answer Key

1. 2-26-5 defines the line to gain: the yard line established when a new series is awarded, 10 yards in advance of the foremost point of the ball unless a penalty follows the ready-for-play — and if it would extend into the end zone, the goal line is the line to gain. 1-2-5 covers the equipment: either a yardage chain joining two rods exactly 10 yards apart, or any other 10-yard indicator with a visible line-to-gain indicator. The line-to-gain indicator fixes the line to gain; the down indicator marks the spot of the ball and shows the number of the down. Game management provides both, and the crew checks them for accuracy before the game. They are operated about 2 yards outside the sideline opposite the press box, and the line-to-gain indicator comes off the sideline when the line to gain is the goal line. Rules 1-2-5, 1-2-5a, 1-2-5b; 2-26-5

2. A shift is the action of one or more offensive players who, after a huddle or after taking set positions, move to a new set position before the ensuing snap. After a huddle or shift, all players of A must come to an absolute stop and remain stationary simultaneously — no movement of hands, feet, head or body — for at least one second before the snap. A shift that simulates action at the snap is a false start, not an illegal shift. Rules 2-39; 7-2-6; 7-1-7a

3. A live ball is a ball in play. It becomes live when the ball has been legally snapped or free kicked and a down is in progress. Rule 2-1-2

4. A dead ball is a ball not in play. The ball is dead during the interval between downs. Rule 2-1-1

5. After the ball is ready for play and before the snap begins, no false start may be made by any A player. It is a false start if (a) a shift or feigned charge simulates action at the snap; (b) any act is clearly intended to cause B to encroach; or (c) any A player on his line between the snapper and the player on the end of his line, after having placed a hand or hands on or near the ground, moves his hand(s) or makes any quick movement. It is a dead-ball foul, 5 yards. If a false start causes B to encroach, only the false start is penalized. Rules 7-1-7, 7-1-8

6. A down is action which starts with a legal snap — beginning a scrimmage down — or when the ball is kicked on a free kick, beginning a free-kick down. A down ends when the ball next becomes dead. Loss of a down is the loss of the right to replay a down — it does not cost a team the ball, it costs them the repeat. Rules 2-7-1, 2-7-2

7. A fumble is any loss of player possession other than by handing, passing or legal kick. Rule 2-18

8. A muff is the touching of a loose ball by a player in an unsuccessful attempt to secure possession. The difference is possession: a fumble starts from possession, a muff never had it. It matters most on the 4-3-1 EXCEPTION, which returns a ball fumbled out of bounds to the spot of the fumble — that exception applies to a fumble and not to a muff. Rules 2-27, 2-18; 4-3-1 EXCEPTION

9. The neutral zone is the space between the two free-kick lines during a free-kick down, and between the two scrimmage lines during a scrimmage down. On a free-kick down it is 10 yards wide; on a scrimmage down it is as wide as the length of the football. It is established when the ball is ready for play. After the snap it may be expanded up to 2 yards behind the defensive line of scrimmage, inside the boundary lines — but on a scrimmage kick it is never expanded into the end zone. Rules 2-28-1, 2-28-2

10. Encroachment occurs when a player is illegally in the neutral zone during the time interval starting at the ready-for-play and until the ball is snapped or free kicked, as in 7-1-1, 7-1-5 or 7-1-6. An entering substitute is not considered a player for encroachment restrictions until he is on his team's side of the neutral zone. Encroachment also occurs when a player violates the free-kick restrictions of 6-1-3a. It is a 5-yard penalty. Rules 2-8-1, 2-8-2; 7-1-5, 7-1-6; 6-1-3a

11. A scrimmage formation requires a minimum of five A players legally on their line at the snap. At the snap, at least five A players on their line must be numbered 50-79, no more than four A players may be backs, and only one of the players not on the line may penetrate the vertical plane through the waistline of his nearest teammate who is on the line — the player under the snapper, who is also considered a back. Rules 2-14-1; 7-2-5a, 7-2-5b; 7-2-3; 2-32-3
