That could mean a couple of things. On a pass play, offensive lineman (center, guard, tackle) are not allowed to cross the line of scrimmage prior to a pass crossing the line of scrimmage. This infraction is called ineligible man down field. On a punt, the only players on the punting team allowed to cross the line of scrimmage prior to the punt are the two players positioned on the end of the line. Should any other player except for those two players cross the line of scrimmage prior to the punt, the infraction is called ineligible man down field.
No it's not. If the ball, after a punt, crosses the line of scrimmage and hits ANY of the receiving team's players it's a live ball. So it's not considered a blocked punt.
From the line of scrimmage.
PF probably means punt formation. This is a formation in which you have (normally) 2 gunners lined up on the outsides who's job is to be the first ones to reach the punt receiver and hopefully tackle the receiver, or down the ball as close to the goal line as possible. The remaining 8 men will line up on the line of scrimmage similar to a regular formation (not all 8 will be literally on the line of scrimmage) whos job it is to block long enough for the punter to make a successful punt, after which they assist in punt coverage. I would imagine that could also be a typo for FP, which would be forward pass. What is the context in which it was used? Can you provide more information?
Yes. As long as there are at least 7 players on the line of scrimmage, any formation is legal.
From the spot where the ball is kicked. Punt yardage is measured from the line of scrimmage.
As far as the NFL is concerned, if both wide receivers are on the same side of the field and on the line of scrimmage, the formation is illegal. There must be 7 players on the line of scrimmage and 3 players on each side of the center. It sounds like your question is describing a situation where there are 4 players on the line of scrimmage on one side of the center and 2 players on the line of scrimmage on the other side of the center. If this is the case, the formation would be deemed illegal and result in a five yard penalty being called against the offense. It is illegal to have a receiver 'covered' by another receiver on the line of scrimmage.
from the line of scrimmage to where it is recovered/goes out of bounds
Not in American football. Kicks must be taken from behind the line of scrimmage. In Canadian football, however, this would be legal.
In HS: On offense, there must be seven or more players lined up on the line of scrimmage when the ball is snapped. If there are less than seven offensive players on the line of scrimmage at the time the ball is snapped the penalty is called an illegal formation. (if there are more than 7, some players that would normally be eligible to be downfield for a pass are ineligible, but it is still a legal formation). In NCAA/NFL: There must be 4 players in the backfield (off the line of scrimmage) at the snap. While the two rules sound the same, the difference occurs when the offense doesn't have all 11 players on the field. In high school, it means less players in the backfield. In the upper levels, it means less players on the line of scrimmage (and it makes the job of the short-wing officials a lot easier when checking the formation). There are also some other rare/unusual rules when governing legality of formations, such as HS requires a man on the line of scrimmage on both sides of the center (usually the guard), in college and pros you need two players on both sides of the center on the line of scrimmage (usually the guard and tackle). Also, the 5 players on the line that are ineligible (the offensive lineman) must wear numbers of ineligible receivers (between 50-69). There is an exception to the player numbers on 4th down FG attempts and PATs.
Runs through the line of scrimmage (line of the players) or gets the football and runs outside the line of scrimmage.
The offense is allowed up to ten players on the line of scrimmage, need one to receive the ball from the center. But the offensive is required to have a minimum of seven players on the line of scrimmage. Defensively all eleven can play on the line of scrimmage.
there must be 7 men on the line of scrimmage, no more no less
A "punt" is when a team chooses to forfeit possession of the ball by kicking it downfield. It is a type of scrimmage kick, which means the ball is snapped from the line of scrimmage on a down play. A "kickoff" is when the ball is kicked to put it into play, either following a score or at the beginning of a half. This is a type of free kick, which does not take place on a scrimmage down. In order to legally punt, the ball must be dropped and then kicked before it touches the ground. To legally kickoff, the ball must be kicked off the ground before any players on the kicking team have moved beyond the line where the ball is placed.
No...all kicks from scrimmage must be done prior to crossing the LOS, same as a forward pass.
False.This question is not asked very well as it only applies to the offense. The offense must have at least 7 players on the line of scrimmage. These can include receivers. It does not mean that the offense must have 7 linemen. Offensive players not on the line of scrimmage must be at least one yard back. The defense, on the other hand, is not required to have any players on the line of scrimmage.
Yes. Just remember that only the two players on each end of the line are potential eligible receivers, if they are wearing eligible numbers. Your formation would have the QB and one other player in the backfield.
The offense must have 7 players on the line of scrimmage.
It depends on why it didn't cross the line of scrimmage. A blocked kick, whether a field goal attempt or a punt, is a live ball. Either team may attempt to advance the ball (but no forward passes are permitted).A field goal attempt or punt that is kicked so poorly that it does not reach the line of scrimmage is governed by the normal rules of the type of kick, a field goal attempt is a live ball and may be advanced by either team, a punt must be touched first by the receiving team.So, if a punt or field goal attempt does not reach the line of scrimmage and is recovered by the opponent, they will receive 1st & 10 from where they recovered it (and advanced it to, if applicable).
On the line of scrimmage, where the ball is spotted.
All passes, runs, and kicks are calculated from the line of scrimmage. It is the one arbitrary line that can be used as a universal point of reference without subjective decisions, and thus can be universally applied. The exception is the field goal; it is calculated from the location of the ball when kicked, except that if there is a penalty, it is still calculated from the line of scrimmage.
Not unless you want to be penalized for it. :-) Rules state you must have at least 7 players on the line of scrimmage for any scrimmage play. You could have more than 7, but that would reduce the number of eligible receivers.
A minimum of 7 players must be on the line of scrimmage. There is no minimum but all 11 can. The 7 player minimum is only for the offense.
