Determining the Enforcement Spot and the Basic Spot

ARTICLE 2.

a. Dead-ball fouls. The enforcement spot for a foul committed when the ball is dead is the succeeding spot.

b. Fouls by the offensive team behind the neutral zone. For the following fouls committed by the offensive team behind the neutral zone, the penalty is enforced at the previous spot: illegal use of hands, holding, illegal block and personal fouls (Exception: If the foul occurs in Team A’s end zone the penalty is a safety.). However, see Rule 6-3-13 for offensive team fouls during scrimmage kick plays.

c. The Three-and-One Principle (Rule 2-33) is as follows:
1. When the team in possession commits a foul behind the basic spot, the penalty is enforced at the spot of the foul.
2. When the team in possession commits a foul beyond the basic spot, the penalty is enforced at the basic spot.
3. When the team not in possession commits a foul either behind or beyond the basic spot, the penalty is enforced at the basic spot.
d. The following are basic spots for the various categories of plays:
1. Running plays.
(a) Previous spot, when the related run ends behind the neutral zone.
(b) End of the related run, when the related run ends beyond the neutral zone.
(c) End of the related run, on running plays that have no neutral zone. 2 Running plays when the run ends in the end zone after change of team
possession (not on a try).
(a) 20-yard line, when a foul occurs after a change of team possession in
the end zone and the result of the play is a touchback.
(b) Goal line, when a foul occurs after a change of team possession in the field of play and the related run ends in the end zone. (Exception: Rule 8-5-1-Exceptions.)
(c) Goal line, when a foul occurs after a change of team possession in the end zone, the related run ends in the end zone, and the result of the play is not a touchback.
3. Pass plays.
Previous spot, on legal forward pass plays.
4. Kick plays.
(a) Previous spot, on legal kick plays unless the foul is governed by
postscrimmage kick rules.
(b) Postscrimmage kick spot, if the foul is governed by postscrimmage kick rules.

I hope this gives a better picture Bob for you.
