Blitz (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 him or force him to hurry his pass attempt. In practice, a blitz involves five or more players rushing during a single down, rather than the four 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 2. History The “red-dog", likely first completed by Carl Battershell, a MAC football le ...

Zone Blitz
In American football, a zone blitz is a defensive tactic that sends additional players to rush the opposing team's quarterback, whilst also unexpectedly redirecting a supposed pass rushing player into pass coverage instead. This tactic also likely includes zone coverage (rather than man-to-man coverage). Like a conventional blitz, the zone blitz tactic assigns five or more players to rush the quarterback in a single down, rather than the usual 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 defensive linemen, while a fourth lineman unexpectedly moves into pass coverage. As in other blitzes, using additional rushers is intended to hurry the quarterback, and potentially cause an incomplete pass, sack, fumble or interception. Redirecting a player who was expected to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tight End
The tight end (TE) is a position in American football, arena football, and Canadian football, on the offense. The tight end is often a hybrid position with the characteristics and roles of both an offensive lineman and a wide receiver. Like offensive linemen, they are usually lined up on the offensive line and are large enough to be effective blockers. On the other hand, unlike offensive linemen, they are eligible receivers adept enough to warrant a defense's attention when running pass patterns. Because of the hybrid nature of the position, the tight end's role in any given offense depends on the tactical preferences and philosophy of the head coach as well as overall team dynamic. In some systems, the tight end will merely act as a sixth offensive lineman, rarely going out for passes. Other systems use the tight end primarily as a receiver, frequently taking advantage of the tight end's size to create mismatches in the defensive secondary. Many coaches will often have one t ...

Fullback (American Football)
A fullback (FB) is a position in the offensive backfield in gridiron football, and is one of the two running back positions along with the halfback. Fullbacks are typically larger than halfbacks and in most offensive schemes the fullback's duties are split among power running, pass catching, and blocking for both the quarterback and the other running back. Many great runners in the history of American football have been fullbacks, including Jim Brown, Marion Motley, Bronko Nagurski, Jim Taylor, Franco Harris, Larry Csonka, 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 ball carrier; they were primarily listed as fullbacks due to their size and did not often perform the run-blocking duties expected of modern fullbacks. Examples of players who have excelled at the hybrid running–blocking–pass-catching role include Vonta Leach, Mike Alstott, William Henderson, ...

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 starting running back. Halfback/tailback The halfback (HB) or tailback (TB) position is responsible for carrying the ball on the majority of running plays, and may frequently be used as a receiver on ...

Linebackers
Linebacker (LB) is a playing position in gridiron football. Linebackers are members of the defensive team, and line up three to five yards behind the line of scrimmage and the defensive linemen. They are the "middle ground" of defenders, playing closer to the line of scrimmage than the defensive backs (secondary), but farther back than the defensive linemen. 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 a linebacker plays their position 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, often called "Mike", is frequently ...

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), although ther ...

Checkdown
In American 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. A screen pass A screen pass is a play in gridiron football consisting of a short pass to a receiver who is protected by a screen of bloc ...

Bump And Run Coverage
Bump and run coverage is a strategy formerly widely used by defensive backs in 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. This originated in the American Football League in the 1960s, one of whose earliest experts was Willie Brown of the Oakland Raiders. Mel Blount of the Pittsburgh Steelers specialized in this coverage to such a point as to cause numerous rule changes (see below) strictly limiting when and where a defender may make contact with a potential receiver in order to make it easier for receivers to run their routes and increase scoring. In contrast, under NCAA rules, contact is allowed anywhere on the field as long as contact is in front of the defender and a pass is not in the air. Technique This play works well against routes that require the receiver to be in a certain spot at a certain time. The disadvantage, howev ...

Cornerback
A cornerback (CB) is a member of the defensive backfield or secondary in gridiron football. Cornerbacks cover receivers most of the time, but also blitz and defend against such offensive running plays as sweeps and reverses. They create turnovers through hard tackles, interceptions, and deflecting forward passes. Other members of the defensive backfield include strong and free 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 fastest players on the field. Because of this, they are frequently used as return specialists on punts or kickoffs. Overview The cornerback’s chief responsibility is to defend against the offense's pass. The rules of American professional football and American coll ...

Safety (American Football Position)
Safety is a position in gridiron football on the 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 and the strong safety. 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 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 pass receivers. Safeties are the last line of defense; they are expected to be reliable tacklers, and many safeties rank among the hardest hitters in football. Safety positions can also be converted cornerbacks, either by design ( Byro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. 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 or 4th down, when the fumbler is the only offensive player allowed to advance the ball, otherwise the ball is ruled dead at the spot of fumble, except when it is recovered for a loss. A fumble is one of three events that can cause a turnover (the other two being an interception or a turnover on downs). Under American rules a fumble may be confused with a muff. A muff occurs where a player dr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
