In 1876 at Massasoit House in Springfield, Massachusetts, Harvard persuaded Princeton and Columbia to adopt an amalgam of rugby's laws and the rules that they were then playing, thus forming the Intercollegiate Football Association ( IFA ).

The centre scrimmager of the side entitled ( and required ) to do so would put the ball down in front of him for play by scrimmage, while both sets of three bodies each (" formed into one compact body " as the rules specified ) were crouched and shoving forward at each other, probably meeting at the shoulders as do the front row of forwards in rugby's set scummage.

Minor violations such as offside ( a player from either side encroaching into scrimmage zone before the play starts ) are penalized five yards, more serious penalties ( such as holding ) are penalized 10 yards, and severe violations ( such as face-masking ) of the rules are typically penalized 15 yards.

This also made it difficult to pass the ball when very close to one's own end zone, since merely dropping back to pass or kick would result in a safety ( rules of the forward pass at the time required the passer to be five yards behind the line of scrimmage, which would make throwing the forward pass when the ball was snapped from behind one's own five-yard line illegal in itself ).

The change was intended to close a loophole in the rules which allowed teams to run an A-11 offense, in which a team could legally be exempted from eligibility numbering restrictions if the player receiving the snap was at least seven yards behind the line of scrimmage.

The various rules codes have additional requirements, all of which have the effect of requiring the ball to go backwards to a player behind the line of scrimmage ( i. e. in the " backfield ").

Beginning regionally again and universally by 1923, the Burnside rules led to the 3-man scrimmage being reduced to the centre alone, the number of players on the field being reduced commensurately from 14 to 12, and a snap rule and neutral zone similar to that of American football was adopted.

The game design rationale for requiring the snap to be a quick and continuous motion to the backfield is to eliminate the need for rules provisions for a live ball in scrimmage.

Under NFL and NCAA rules, there are actually two lines of scrimmage at the outset of each play: one that restricts the offense and one that restricts the defense.

These down-and-distance rules, combined with the already-established line of scrimmage, transform the game from a variation of rugby or association football into the distinct sport of American football.

The Jack cannot blitz, but under new, more defense-friendly rules, the Jack Linebacker may roam sideline to sideline within five yards of the line of scrimmage and drop into coverage once the Quarterback pump fakes.

The most common way for a scrimmage / scrummage to be so awarded ( there being no referee to actually award one, but as the rules specified ) would be the occurrence of a stalemate between the player with the ball ( who would declare " held ") and opponents holding him ( who would call, " Have it down ").

Although the rules of playing the ball were different as to whether it was in scrimmage or not, the early rules did not draw a clear distinction between players in or out of scrimmage, and did not require players in scrimmage to bind.

The modern rugby union scrummage and ruck, the rugby league play-the-ball ( also referred to as a " ruck "), and the American football snap and scrimmage ( later adopted by Canadian football ) were all derivatives of the early scrummage, and responsive in different ways to problems encountered in the way the rules regarding it were written and administered.

Although ESPN. com columnist Gregg Easterbrook stated in 2008 that National Football League ( NFL ) pass interference rules apply throughout the field of play, no matter where the intended receiver is located, the NFL itself says otherwise, stating on its official site that " there can be no pass interference at or behind the line of scrimmage ".

For approximately the decade of the 1910s in American football, the rules discouraged the quick kick by requiring that the ball be kicked from at least 5 yards behind one's line of scrimmage.

At this point, all general rules apply as for a field goal attempt from scrimmage.

Because of the rules of the game, it frequently matters whether a player of the offense is on the line of scrimmage or in the backfield, and in those cases the descriptor " wide receiver " is insufficient and " end in motion " ( except in Canadian football, where they're allowed to be shuffling sideways along the line of scrimmage when the ball is snapped ) is nonsense, although it may reflect the way the player in question is listed on the roster.

Among these important changes were the introduction of the line of scrimmage and of down-and-distance rules.
