Blitz (gridiron Football)
In gridiron football, blitzing is a tactic used by the defense to disrupt pass attempts by the offense. During a blitz, a higher than usual number of defensive players will rush the opposing quarterback, in an attempt either to tackle them or force them to hurry their pass attempt. In practice, a blitz involves five or more players rushing during a single down, rather than the four or three rushers used during normal play. For example, in a defense that normally uses four defensive linemen to rush, a blitz can be created by adding one or more linebackers or defensive backs. Blitzing is a higher-risk strategy, as fewer defensive players are left to cover receivers or to defend against running plays. However, a successful blitz will result in a sack or will force the quarterback into making an error. The term "blitz" is German for "lightning" and a reference to the blitzkrieg tactic of World War II. History The term "red-dog" referred to a rushing linebacker that create ...

Zone Blitz
In American football, a zone blitz is a defensive tactic that sends additional players to Pass rush, rush the opposing team's quarterback, whilst also unexpectedly redirecting a supposed pass rushing player into American football strategy#Pass defence, pass coverage instead. This tactic also includes Zone defense in American football, zone coverage (rather than man-to-man coverage). Like a conventional Blitz (gridiron football), blitz, the zone blitz tactic assigns five or more players to rush the quarterback in a single Down (gridiron football), down, rather than the usual three or four players. However, unlike a conventional blitz, the zone blitz uses players who are initially positioned to rush (for example, the defensive ends) to instead give pass coverage. For example, a zone blitz may involve two linebackers adding to the rush of three Lineman (gridiron football)#Defensive line, defensive linemen, while a fourth lineman unexpectedly moves into pass coverage.

Fullback (American Football)
A fullback (FB) is a position in the offense (sports), offensive backfield in gridiron football and is one of the two running back positions along with the halfback (American football), halfback. Fullbacks are typically larger than halfbacks, and, in most offensive schemes, the fullback's duties are split among power running, reception (gridiron football), pass catching, and blocking (American football), blocking for both the quarterback and the other running back. Many great rush (gridiron football), runners in the history of American football have been fullbacks, including Jim Brown, Marion Motley, Bronko Nagurski, Jim Taylor (fullback), Jim Taylor, Franco Harris, Larry Csonka, Tom Rathman, John Riggins, Christian Okoye, and Levi Jackson. However, many of these runners would retroactively be labeled as halfbacks, due to their position as the primary carry (gridiron football), ball carrier; they were primarily listed as fullbacks due to their size and did not often perform the ru ...

Running Back
A running back (RB) is a member of the offensive backfield in gridiron football. The primary roles of a running back are to receive American football plays#Offensive terminology, handoffs from the quarterback to Rush (American football)#Offense, rush the ball, to line up as a receiver to catch the ball, and Blocking (American football), block. There are usually one or two running backs on the field for a given play, depending on the offensive formation. A running back may be a Halfback (American football), halfback (in certain contexts also referred to as a "tailback" — see #Halfback/tailback, below), a wingback (American football), wingback, or a Fullback (American football), fullback. A running back will sometimes be called a "feature back" if he is the team's key player/more prominent running back. With the increase in pass-oriented offenses and single set back formations, it is more common to refer to these players as simply running backs. Halfback/tailbac ...

Linebackers
Linebacker (LB) is a playing position in gridiron football. Linebackers are members of the defensive team, and typically line up three to five yards behind the line of scrimmage and so back up the defensive linemen. They play closer to the line of scrimmage than the defensive backs (secondary). As such, linebackers play a hybrid role and are often the most versatile players on the defensive side of the ball; they can be asked to play roles similar to either a defensive lineman (such as stopping the runner on a running play) or a defensive back (such as dropping back into pass coverage). How linebackers play their positions depends on the defensive alignment, the philosophy of the coaching staff, and the particular play the offense may call. Linebackers are divided into middle linebackers, sometimes called inside linebackers, and outside linebackers. The middle linebacker is frequently the "quarterback of the defense". His central role on the field means he is in the best posit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Draw Play
A draw play, or simply draw for short, is a type of American football play. The draw is a running play disguised as a passing play. It is the opposite of a play-action pass, which is a passing play disguised as a running play. The play is often used in long yardage situations. The idea behind a draw play is to attack aggressive, pass-rushing defenses by "drawing" the defensive linemen across the line of scrimmage towards the passer while the linebackers and defensive backs commit to positioning themselves downfield in anticipation of a pass. This creates larger gaps between defenders and thereby allows the offense to effectively run the ball. Draw plays are often run out of the shotgun formation, but can also be run when the quarterback is under center. These types of draw plays are sometimes referred to as "delayed handoffs". The running back will most often run straight downfield through the hole in the "A- gap" (the space between the center and the offensive guard), althoug ...

Checkdown
In gridiron football, a checkdown pass is when the quarterback attempts to complete a short, accurate pass, typically to a running back or tight end, as a last option when the primary option(s) as designed by the play call are covered. The term means that the quarterback has "checked down" his list of receivers. Because the quarterback does not look for the checkdown pass until after they have scanned for open receivers down the field for about 3–4 seconds, the defensive line has had time to enter the backfield and so a checkdown pass is often thrown in the face of pressure from the defensive line. Alternatively, if the quarterback is inexperienced or the defensive team has sent a blitz, with linebackers and/or defensive backs also looking to sack the quarterback, the checkdown may also turn out to be the quarterback's second or even first look.

Bump And Run Coverage
Bump and run coverage is a strategy formerly widely used by defensive backs in NFL, American professional football in which a defender lined up directly in front of a wide receiver and tried to impede him with arms, hands, or entire body and disrupt his intended route. History In one view, the bump and run originated in the American Football League in the 1960s, one of whose earliest experts was Willie Brown (American football), Willie Brown of the Oakland Raiders. Before playing for the Raiders, Brown was a rookie with the Denver Broncos in 1963 and played there through 1966. In another version of the bump and run's origins, Brown created the bump and run defense as a linebacker at Grambling State University, Grambling University, and then first brought it to professional football in 1963, when he was a defensive back with the Denver Broncos. In yet another version of possible origins, Jack Faulkner gets significant credit for development of the bump and run. Faulkner was head ...

Cornerback
A cornerback (CB) is a member of the defensive backfield or secondary in gridiron football. Cornerbacks cover Wide receiver, receivers most of the time, but also blitz and defend against such Play from scrimmage, offensive running plays as sweeps and reverses. They create Turnover (gridiron football), turnovers through hard tackle (football move), tackles, interceptions, and pass deflection, deflecting forward passes. Other members of the defensive backfield include strong and free Safety (gridiron football position), safeties. The cornerback position requires speed, agility, strength, and the ability to make rapid sharp turns. A cornerback's skill set typically requires proficiency in anticipating the quarterback, backpedaling, executing single and zone coverage, disrupting pass routes, block shedding, and tackling. Cornerbacks are among the 40-yard dash#Average time by position, fastest players on the field. Because of this, they are frequently used as return specialists on ...

Safety (American Football Position)
Safety (S), historically known as a safetyman, is a position in gridiron football on the American football positions#Defense, defense. The safeties are defensive backs who line up ten to fifteen yards from the line of scrimmage. There are two variations of the position: the free safety (FS) and the strong safety (SS). Their duties depend on the defensive scheme. The defensive responsibilities of the safety and cornerback usually involve pass coverage towards the middle and sidelines of the field. While American (11-player) formations generally use two safeties, Canadian (12-player) formations generally have one safety and two Halfback (Canadian football), defensive halfbacks, a position not used in the American game. As professional and college football have become more focused on the passing game, safeties have become more involved in covering the Eligible receiver, eligible pass receivers.Safeties are the last line of defense; they are expected to be reliable tacklers, and many ...

Fumble
A fumble in gridiron football occurs when a player who has possession and control of the ball loses it before being downed (tackled), scoring, or going out of bounds. By rule, it is any act other than passing, kicking, punting, or successful handing that results in loss of ball possession by a player. Unlike other events which cause the ball to become loose, such as an incomplete pass, a fumbled ball is considered a live ball, and may be recovered and advanced by any member of either team. A fumble may be forced by a defensive player who either grabs or punches the ball or butts the ball with their helmet (a move called "tackling the ball"). A fumbled ball may be recovered and advanced by either team (except, in American football, after the two-minute warning in either half/overtime or on 4th down at any point during the game, when the fumbler is the only offensive player allowed to advance the ball, otherwise the ball is ruled dead at the spot of the fumble, except when it is ...

Interception
In Ball game, ball-playing Competitive sport, competitive team sports, an interception or pick is a move by a player involving a pass of the ball—whether by foot or hand, depending on the rules of the sport—in which the ball is intended for a player of the same team but caught or otherwise brought under control by a player of the opposing team, who thereby usually gains possession of the ball for their team. It is commonly seen in football, including American football, American and Canadian football, as well as association football, rugby league, rugby union, Australian rules football and Gaelic football, as well as any sport by which a loose object is passed between players toward a goal. In basketball, this is called a Steal (basketball), steal. Gridiron football In American football and Canadian football, an interception occurs when a forward pass that has not yet touched the ground is caught by a player of the defensive team.
