Titans defensive end Kyle Vanden Bosch, a quality player in a defense, points out the 's effectiveness: "We have used front principles where I'm outside the offensive tackle as well as defensive tackle Albert Haynesworth, and it does cause hesitation from the blockers.
And with four of its seven defenders standing up in a look, the defense has the flexibility to send its outside linebackers in different ways. A double inside twist, in which both outside linebackers blitz between the tackle and guard while the defensive end goes to the outside, is a favorite of defenses and an excellent call against a classic pocket passer.
A defense will run its own stunt game in order to free one defender for a shot on the quarterback. It has worked in the past, but offensive linemen now sit on stunt fronts and pick up the twist stunts. In this look, defensive coaches must be careful that the quarterback doesn't break containment.
A defense's answer to quarterbacks who throw from the midline 5 yards straight back from the center is called a double twist, but it also has a number of issues. Will the defensive end get to the passer in time? Will the offensive guards pass the defensive tackles and set for the looping ends? However, a linebacker blitz shows one of the many ways a defense can bring pressure on the quarterback.
The inside linebacker eats up the guard, setting an effective outside pressure into motion. Two weeks ago against the Cowboys , the Steelers ' creative defensive coordinator, Dick LeBeau , occasionally put both outside linebackers next to each other rather than one on each side in the The outside linebacker stepped inside the other linebacker, and it was clear sailing to the quarterback. The defense offers flexibility in looks, features quicker athletes rushing from the outside and forces offensive adjustments that empty the backfield.
Not many teams want to be in a defense when the opponent has a 3-by-2 empty set with no one in the backfield except the quarterback. However, teams are ready for that adjustment with a three-man rush while many four-man fronts have to pop out a lineman into coverage.
At lower levels the is not particularly popular because many coaches consider it weak against the run due to the fact there are only four down linemen. As the name suggests, the Cover 3 has three defenders in deep zone coverage.
A defense is a defense that incorporates four 4 down linemen and three 3 linebackers. You will also see two 2 cornerbacks, one strong safety, and one free safety.
It Covers All Zones Well — While it is considered a four-deep defense, the Cover 4 defense can also provide a blanket across the shorter passes, as long as the defensive personnel has the ability to read, react, and provide help.
A curl route, also called a hitch or hook sometimes a button hook , is a pattern run by a receiver in American football, where the receiver appears to be running a fly pattern but after a set number of steps or yards will quickly stop and turn around, looking for a pass. An out route or down and out or jet route is a pattern run by a receiver in American football. The other difference between a hitch and curl route is that depending on how the defensive back is covering the wide receiver, the receiver has the option to turn towards the quarterback or away to catch the ball.
Out Route. In American football , the 3—4 defense is a defensive alignment consisting of three down linemen and four linebackers. The 3—4 defense declined in popularity over the years, but has found renewed use by modern professional and college football teams.
The 3—4 defense is so named because it involves 3 down linemen and 4 linebackers. There are usually 4 defensive backs.
However, most teams since the s have been using the defense , primarily because football is fundamentally a "rush first" game, and the 4—3 defense's 4 down linemen make rushing more difficult by adding one more down lineman to fill gaps. By the same token, fast linebackers, sitting back to survey the offensive set, can key in on an inside ball carrier and "hit the gaps" quickly to offer help to the 3 down linemen when defending the rush.
The Cardinals already incorporate the 5—2 defense, an older variation of the 3—4, in some of their defensive schemes. The Miami Dolphins have switched to a defense with the hiring of Kevin Coyle as their new defensive coordinator under new head coach Joe Philbin.
The Ravens run a hybrid defense and occasionally shift to 4—3 schemes during games. With the hiring of defensive coordinator Dom Capers , the Green Bay Packers have switched to a 3—4 defense With the hiring of Chuck Pagano as their new head coach, the Indianapolis Colts have switched to defense.
The Dallas Cowboys will also switch to the defense with the hiring of Monte Kiffin as their defensive coordinator. Sean Payton announced that the Saints will switch to the 3—4 defense for the season under new defensive coordinator Rob Ryan , and the Cleveland Browns will switch to a 3—4 "stick-em" defense. With the hiring of Chip Kelly as head coach and Bill Davis as defensive coordinator, the Eagles will shift to a hybrid defense that will incorporate 3—4 and 4—3 schemes.
Typically, there are two major variations of the defense. Both variations are directly related to coverage schemes on obvious passing downs. For the first type, the outside linebackers will rush the quarterback, the great majority of the time. On key situations, the rush linebacker will be sent to cover the flat on the opposite side of the blitzing defensive back; this is the infamous " zone blitz ".
The other common defense is typically associated with the New England Patriots. This scheme requires outside linebackers to have the ability to back pedal and drop into coverage.
Of course they do rush the passer at times, it is just that they are much more likely to drop into coverage. The Chicago Bears and Minnesota Vikings are the only NFL teams that have never used the 3—4 as their base defense though the Vikings have used 3—4 alignments for certain plays. Before the season, the Washington Redskins had also never run a base 3—4, but under the direction of new defensive coordinator Jim Haslett , the Redskins have adopted the 3—4 and its many variants, such as the 2—4—5 and the 1—5—5, based on formations used by the Pittsburgh Steelers.
Conversely, the Steelers have used the 3—4 as their base since , the season after Pro Football Hall of Fame defensive tackle Joe Greene and end L. Greenwood retired. The 3—4 defense was originally devised by Bud Wilkinson at the University of Oklahoma in the s. By the mids, only a few teams used a 3—4 defense, most notably the Buffalo Bills and Pittsburgh Steelers.
The defensive line is made up of a nose tackle NT and two defensive ends DEs. Linemen in 3—4 schemes tend to be larger than their 4—3 counterparts to take up more space and guard more territory along the defensive front. They must be strong at the point of attack and are aligned in most cases head-up on an offensive tackle. First and foremost, they must control run gaps.
Size and strength become more of a factor for linemen in 3—4 defenses than in 4—3 defenses because they move primarily within the confines of line play and seldom are in space using athletic ability.
