638:(LB): Linebackers are positioned 2 to 4 yards behind the defensive line. The 4-3 defense has 3 linebackers, who are categorized as strong, middle, and weak (SLB, MLB, WLB; also called Sam, Mike, and Will). This is not an indication of strength; it instead refers to the positioning of the linebackers relative to the offense. Strong linebackers line up on the same side as the tight end and weak side away from the tight end. A 3-4 defense will use 4 linebackers, who are indicated by their side (right/left) and positioning (inside/outside).
670:. The exception is during a field goal attempt, PAT, or punt. The defense is only allowed a maximum of 6 players on the line of scrimmage on either side of the snapper at the snap. Having 7 or more players on the line on one side will result in an illegal formation penalty. The standard defensive formations in use at most levels of American football are the result of decades of experimentation, trial, and error, along with rule changes in the 1950s that eliminated the

In fact, if one of these players bats, muffs, or catches a legal forward pass before it is touched by a defensive player, it is a penalty for illegal touching (5 yards plus loss of down). Typically you must have 5 players numbered 50-79 on the line of scrimmage, but there are exceptions to this rule when the offense is lined up in scrimmage kick formation (punt or field goal).

The 7 players are not required to be next to each other, so they may spread out across the width of the field, but this is rare; most offenses place at least 5 players together in a continuous line. Teams may place more than 7 players on the line, but only the player at each end of the line may be an eligible receiver, so generally this only occurs with the special formations used in kicking and punting situations.

captain, and he will generally announce it to spectators as well. After reporting as eligible, those players may line up at any legal position just as if they were normally eligible receivers. Offenses sometimes use this tactic in a short yardage situation to provide extra blocking, and some plays are even designed for a designated player (i.e.: with numbers 50-79) to receive a pass.
656:(FS, so called because they are "free" to roam where needed). Cornerbacks are almost always responsible for defending against the pass, particularly against wide receivers; often they are the fastest defensive players. Safeties also defend against the pass, matching up on tight ends and backs, but they are positioned in the center of the field to be prepared to stop the run as well.

Most formations have a "strong" side (the side with the tight end, or the side with more players) and a "weak side" (the side opposite the tight end, or the side with fewer players).

The other players not on the line (usually 4 in number) may be positioned anywhere, but all must be at least 1 yard behind the 7 or more players on the line of scrimmage. The traditional saying is "7 on the line, 4 in the backfield" but this is something of a misnomer, as "backfield" usually refers
