I thought I had made a thread like this in previous years but I guess with the software update it disappeared.
- No such thing as "offside" in NFHS and there is no provision allowing the defense to "get back." Encroachment is dead-ball foul as soon as either team enters the neutral zone.
- A "catchable" ball is not a factor of the pass interference rules.
- There is no "tackle box" for intentional grounding purposes. A QB must always throw a forward pass in the vicinity of an eligible receiver.
- An unsuccessful field goal does not go back to the previous spot. It is treated just like a punt (touchback if it crosses the goal line).
- Any kick that crosses the goal line is an automatic touchback. A kick is a kick until it is possessed. So if a muffed kick crosses the goal line, it's a touchback.
- A blocked extra point is dead immediately; an intercepted two-point try is dead immediately.
- In OHSAA overtime the ball is dead immediately when the defense gains possession.
- There is no previous spot enforcement for fouls by the offense behind the line of scrimmage. For example, holding by a lineman behind the LOS is generally enforced from the spot of the foul, not the previous spot. Yes, that means holding is often a more severe penalty in high school than NCAA or NFL.
- The holder for a field goal cannot pitch the ball from his knee on a fake. He must rise or else the ball is dead.
- The only fouls that include automatic first downs are the "roughing" personal fouls - passer, kicker/holder, and snapper.
- Fouls by the defense during a successful field goal, try, or touchdown-scoring play are not declined by rule. The offense can have the penalty enforced on the try (for a foul during a TD play) or the kickoff.
- Hurdling is a foul. But only if the player being hurdled is contacting the ground with no part of his body other than one or both feet.
- Personal fouls and unsportsmanlike conduct fouls are not the same thing. PFs involve contact and two by one player does not require a DQ. UNS is always noncontact and two by one player results in a DQ.
- Targeting only includes above-shoulder contact and does not result in DQ unless deemed flagrant. Contact initiated with the crown of the helmet at or below the shoulders is spearing.
- Headhunting is not football.
- Most "big hits" and athletic plays (i.e. runners hurdling defenders) that are sensationalized on accounts like Jukes are illegal.
