This is why I hate the NFHS definitions of loose ball and run play. I don't like that fumbles are inconsistent with classification when behind or beyond the NZ.
I've actually submitted a rule change that never gets past (or to) my state interpreter where the basic spot for a run that ends behind the NZ is the previous spot. This would also classify all fumbles and backward passes as RUN plays. So the only time you would have a loose ball play (with basic spot being the previous spot) is during a legal forward pass or scrimmage/free kick. Much simpler to understand.
For those that are curious, here is the proposal:
10-4-2. The basic spot is the previous spot…
d. When the related run ends behind the neutral zone before a change of team possession.
10-4-4. The basic spot is the spot where the related run ends for a foul which occurs during a running play as defined in 10-3-2, unless 10-4-2d applies.
10-3-1. A loose-ball play is action during:
c. A backward pass (including the snap), illegal kick or fumble made by A from in or behind the neutral zone and prior to a change of team possession.
Rationale:
This change would solve an inequity in enforcement of defensive fouls where the run ends behind the neutral zone and also clean up the definitions of run and loose ball plays. Currently, for example, if a QB gets sacked 12 yards behind the LOS, and there was Defensive Holding on the play, the foul is enforced from the end of the run, and the offense would lose 2 yards on a play where there was a defensive foul. This change would help the Offensive/Defensive balance in penalty enforcement while keeping the All-But-One principle in-tact.
Additionally, this would help clean up definitions of loose ball and running play. It’s very confusing to new officials when we teach that fumbles beyond the LOS are run plays and fumbles behind the LOS are loose ball plays. Under the change to 10-3-1, ALL backward passes and fumbles would be classified as RUNS, which would make understanding the rule better for new officials.
