A Challenge!

Thanks to all.

I've also heard the "all but one" referred to as the "3 and 1". If you hear someone say the 3 and 1 you'll be in the know.

Is the all-but-one principle the same for each of the NFL, NCAA, and NFHS?

Are there any differences between the codes? I know that the NFL has exception after exception in penalty enforcement, so perhaps the Fed and college are exactly the same, or very close in penalty administration?

No, they are different. The #1 example which is on TV in every NCAA game is holding by the offense on a pass play. A75 holds 5 yards behind the LOS and the pass is incomplete. In NCAA the penalty is enforced from the previous spot while NF enforces it from the spot of the foul.

NCAA Basic Spot
ARTICLE 10. When “basic spot’’ is stated in a penalty, fouls during a
running play, a legal pass play or a legal kick play are penalized from
the “basic spot.’’ Fouls by the offensive team behind the “basic spot’’ are
enforced from the spot of the foul.
The following are the basic spots for enforcement on running plays,
forward pass plays and legal kick plays:

a. The basic spot on running plays when the run ends beyond the neutral
zone is the spot where the related run ends, and fouls by the offensive
team behind the basic spot are spot fouls (Rules 2-30-4 and 10-2-2-c-1)
(Exceptions: Offensive team facemask, illegal use of hands, holding,
illegal block and personal fouls, behind the neutral zone, are enforced
from the previous spot. Safety if the foul occurs behind Team A’s goal
line).

b. The basic spot on running plays when the run ends behind the neutral
zone is the previous spot, and fouls by the offensive team behind the
basic spot are spot fouls (Rules 2-30-4 and 10-2-2-c-2) (Exceptions:
RULE 2-25 / DEFINITIONS FR -55
Offensive team facemask, illegal use of hands, holding, illegal block
and personal fouls, behind the neutral zone, are enforced from the
previous spot. Safety if the foul occurs behind Team A’s goal line).

c. The basic spot on running plays that occur when there is no neutral zone
(interception runbacks, kick runbacks, fumble advances, etc.) is the spot
where the related run ends, and fouls by the offensive team behind the
basic spot are spot fouls (Rules 2-30-4 and 10-2-2-c-3) (Exceptions:
Rule 8-5-1 Exceptions).

d. The basic spot on legal forward pass plays is the previous spot, and fouls
by the offensive team behind the basic spot are spot fouls (Rules 2-30-1
and 10-2-2-d).

Exceptions:
1. Defensive pass interference may be a spot foul.
2. Enforce roughing the passer on a completed forward pass from the
end of the last run when it ends beyond the neutral zone and there is
no change of team possession during the down (A.R. 2-30-4-I and
II).
3. Enforce illegal-touching fouls from the previous spot.
4. Enforce offensive team facemask, illegal use of hands, holding,
illegal block and personal fouls, behind the neutral zone, from the
previous spot (Exception: Safety if the foul occurs behind Team A’s
goal line).

e. The basic spot on legal kick plays before a change of possession is the
previous spot, and fouls by the offensive team behind the basic spot are
spot fouls (Exceptions: Offensive team facemask, illegal use of hands,
holding, illegal block and personal fouls, behind the neutral zone, are
enforced from the previous spot. Safety if the foul occurs behind Team
A’s goal line) (Rules 2-30-2 and 3 and 10-2-2-e) (Rule 9-1-4-b on
scrimmage kicks).

Works for offensive fouls..doesn't it?

Granted ABO doesn't hit the Defense, where it hurts them the most.

Assuming that the original poster was working with FED rules, do you see what you guys have done? You've made it more confusing.

For me, CMathews has the best explanation because of its simplicity. I like to think in those terms and not work with "shortcuts."

They've been diverging more & more over the decades. They all still use 3&1 to at least some extent. Before about 1970, very close.

Some enforcements have gone back & forth since penalties for them were established. NCAA's defensive pass interference was SOF, then previous spot, then SOF again, then previous spot again. Options for free kicks out of bounds have been a favorite for changing repeatedly.

NCAA was the last to eliminate loss of ball penalties, the last going in 1970 give or take a year.
