Dinwiddie Proud asked for a list of differences between NFHS and NCAA rules.
OK, I'll try to hit a few of the major ones. I found a document that is a summary, and it's an 11 page Word document in 12 pt type.
Needless to say, there are many differences, and both codes are vastly different from NFL rules. (The only NFL rule I hear about with any regularity is the one that says a defensive player can't touch a receiver more than 5 yards downfield. That doesn't even exist in NCAA, much less high school.)
I will say that if you learn the rules based on what the TV guys say about them, you're likely misinformed. I watch a lot of football at the commentators say so many things that are just plain wrong that it's embarrassing.
The BIGGIES
Pocket
--The NCAA defines a pocket as between the original starting spot of the offensive tackles, and allows QUARTERBACKS to dump the ball outside of the pocket. (Other players who attempt passes have no such liberties). NFHS has no pocket definition and does not allow passers to dump the ball without a receiver in the area of the pass.
Facemask
--Grasping the facemask without pulling, turning or twisting (incidental) is no longer a foul in NCAA. The same action is still a foul with a 5-yard penalty in NFHS.
Pass interference
--Faceguarding is not a foul in NCAA. It is pass interference in NFHS.
--There is no pass interference in NCAA is the pass is deemed uncatchable. That stipulation does not exist in NFHS. The language of the rule only requires that the pass is thrown in the direction of the players involved in the interference.
Blocking below the waist
--NCAA allows blocks below the waist if a wide variety of conditions are met and people are going in certain directions. It's a lot like the U.S Tax Code, but more complex. NFHS allows blocks below the waist only by players on the line of scrimmage at the snap and only while the ball is in the free blocking zone, which isn't very long.
Kicks into endzone
--Kickoffs and punts that cross the goal line can be returned if caught in the endzone, but are dead if they touch the ground first in NCAA. All kicks that break the plane of the goal line are touchbacks in NFHS
--Kickoffs that result in a touchback are placed at the 25 yard line in NCAA. All touchbacks are placed on the 20 in NFHS.
Breaking the huddle with 12
--Both codes require a replaced player to depart the huddle within 3 seconds of the substitute entering the huddle. If the huddle breaks in that 3 seconds, it's a foul in NCAA and not in NFHS.
Encroachment
--A defensive player who jumps across the line of scrimmage who gets back on his side before the snap is OK. Jumping across the neutral zone is a deadball foul in NFHS.
Penalty enforcement
--Automatic first downs -- All personal fouls or unsportsmanlike fouls on the defense, as well as defensive pass interference, result in an automatic first down. In NFHS, there are only four fouls that carry an automatic first down and they all include the word "roughing."
Roughing the kicker
Roughing the passer
Roughing the snapper
Roughing the holder
--Fouls that occur behind the line of scrimmage during pass plays are enforced from the previous spot in NCAA. In NFHS, fouls by the offense behind the line during pass plays are enforced from the spot of the foul.
--NCAA has a series of penalties that, in certain circumstances, include a 10-seccond run-off of the clock. NFHS has no penalties that include timing adjustments.
--Intentional grounding is placed at the spot of the pass in NCAA. A 5-yard penalty is added in NFHS.
--Spiking the ball to stop the clock allowed from shotgun if it is immediate in NCAA. Only a QB taking a hand to hand snap under center is allowed to clock the ball in NFHS.
--Defensive pass interference is awarded at the spot of the foul if the spot is less than 15 yards from the line of scrimmage in NCAA. Also, DPI does not adhere to the half-the-distance provisions inside the 30 yards line. The full yardage is marked off at any point, not to go nearer the goal line than the 2 yard line. In NFHS, DPI is always a 15 yard penalty (with no automatic first down) but will be a half-the-distance foul inside the defense's 30 yard line.
The SELDOM SEEN
--NCAA overtimes start at the 25 and have the chance to earn a first down.
NFHS starts at the 10, the chains are not used and the line to gain is ALWAYS the goal line.
--If a game goes to the third (or more) OT period, teams are required to go for 2 on PATs. NFHS has no such requirement.
--NCAA does not allow tripping. NFHS says you can trip the runner.
--A turnover on a try is still a live ball in NCAA and defense can gain possession and score 2 points on a PAT by scoring a touchdown. A turnover ends a try in NFHS.
--Holders can pitch the ball with a knee on the ground in NCAA. In NFHS, this ends the play.
--In NCAA, a fumble on fourth down that goes forward is returned to the spot of the fumble is the offense recovers. No special fourth down rule exists in NFHS.
--After a fair catch, a team cannot line up for a free kick that would score 3 points if the kick goes through the goal. In NFHS, they can attempt a field goal from free kick positions after a fair catch. (This is also allowed in the NFL. No idea what NCAA has against it.)
EQUIPMENT
--NCAA, for reasons unclear to me, allows pants that do not cover the knees. NFHS requires knee to be covered.
--NCAA allows towels only if they are no larger than 4"x12" and everyone on the team wears same color. NFHS allows any solid color and the no smaller than 4"x12.
--NCAA bans overbuilt facemasks. NFHS does not (yet).
--NCAA does not require shoes (I'm guessing the fad of barefoot kickers 30 years ago led to this. NFHS requires shoes.
--NCAA requires teammates to wear matching socks. NFHS does not.
--Hash marks are 60 feet from each sideline in NCAA, 53 feet 4 inches (field divided into thirds) in NFHS.
--Goal posts are 18'6" wide in NCAA, 23'4" in NFHS
There are a lot more that I didn't even touch on because they hardly ever come up. Feel free to ask about them or anything on this list.
