Run Line Nfl

In American football, the 3–4 defense is a common defensive alignment consisting of three down linemen and four linebackers. It is a called a 'base defense' because it is the default defensive alignment used on 'base downs' (1st and 2nd downs). However, defenses will readily switch to other defensive alignments (such as a nickel defense or a dime defense) as circumstances change. Alternatively, some defenses use a 4–3 defense.

Run defense matters. Mack’s overall grade of 95.2 was also far higher than Beasley’s 74.2 because Khalil Mack was one of the best run defenders in the game, capable of shedding blocks and knifing into the backfield to blow up plays. Carroll is bringing Rams long-time assistant offensive line coach Andy Dickerson from L.A. To be the Seahawks’ new run-game coordinator. That’s according to a report by NFL Network’s Mike.

Overview[edit]

The 3–4 defense incorporates three defensive linemen – two defensive ends and one nose tackle, who line up opposite the other team's offensive line. Those three players are responsible for engaging the other team's offensive line, allowing the four linebackers to either rush the quarterback or drop back into coverage, depending on the situation. While the role of the defensive linemen is fairly consistent, the linebackers allow for the flexibility and versatility of the 3–4 scheme, and give defensive coaches nearly limitless options to confuse the other team's players and coaches. Depending on the situation, any number of linebackers can blitz, fake a blitz, 'spy' the quarterback or running back, or cover receivers. In key situations, a rush linebacker may be sent to cover the flat on the opposite side of the blitzing defensive back; this is called a 'zone blitz'.

After becoming the predominant defensive alignment in the late 1970s and early 1980s,^[1] the 3–4 defense declined in popularity over the next two decades, but experienced a resurgence in the 2000s among both professional and college football teams. As of 2020, NFL teams that regularly incorporate the 3–4 defensive alignment scheme as a base include the Green Bay Packers, Los Angeles Rams, Pittsburgh Steelers, Baltimore Ravens, New York Giants, New York Jets, Miami Dolphins, Tampa Bay Buccaneers, Denver Broncos, Tennessee Titans, Houston Texans, Chicago Bears, and Arizona Cardinals.

The Philadelphia Eagles ran the 3–4 from 2013 to 2015 but switched back to the 4–3 for the 2016 season. The New England Patriots returned to a 4–3 defensive front at the end of the 2011 season but use more of a hybrid employing some 3–4 looks. The Cleveland Browns used the 3–4 in 2016, but returned to the 4–3 in 2017 under new defensive coordinator Gregg Williams, and kept the formation under new defensive coordinator

The New York Jets announced that despite hiring Gregg Williams as their new defensive coordinator they would continue to employ the 3–4 defense in 2019, opting to stay with the scheme that better suits their current roster instead of switching to the defense Williams usually used.

In 2018, the Detroit Lions switched to a hybrid 3–4/4–3 defensive front after former Patriots defensive coordinatorMatt Patricia took over as head coach.

In 2019, the Tampa Bay Buccaneers switched to a 3–4 defense under new defensive coordinator Todd Bowles, who previously ran the 3–4 defense with the New York Jets.

The Carolina Panthers ran a 3–4 base defense in the 2019 season for the first time since the late 1990s under their first head coach, Dom Capers.

The Arizona Cardinals ran the 3–4 under coordinators Todd Bowles and James Bettcher from 2013–17, but switched to the 4–3 in 2018 under head coach Steve Wilks, who ran the 4–3 as defensive coordinator for Ron Rivera with the Carolina Panthers. In 2019, the Cardinals returned to the 3–4 under new defensive coordinator Vance Joseph, the former Broncos head coach hired by new Arizona coach Kliff Kingsbury.

New Rams head coach Sean McVay hired Wade Phillips as defensive coordinator prior to 2017. Phillips switched the Rams to the 3–4, the first time the team used it since the early 1990s, prior to the franchise's move to St. Louis. Phillips was fired at the conclusion of the 2019 season.

The Kansas City Chiefs switched to a hybrid 4–3 defense in the 2019 season with the hiring of new defensive coordinator Steve Spagnuolo.

The Pittsburgh Steelers have used the 3–4 as their base defense since 1982, the season after Hall of Fame defensive tackle Joe Greene and end L. C. Greenwood retired. In fact, the Steelers were the only NFL team to use the 3–4 defense during the 2001 season, but finished the season as the number one defense in the NFL.^[2] It is believed that the Steelers' success with the 3–4 defense is the primary reason why many NFL teams have started returning to the formation.^[3]

The New York Giants, after a long time running the 4–3 defensive front, returned to a 3–4 in 2018 with the hiring of James Bettcher as their defensive coordinator. Olivier Vernon moved from defensive end to outside linebacker. In 2020, the Giants will run a hybrid defense including elements from both the 4–3 and 3–4 with the hiring of Patrick Graham as the team's defensive coordinator.

In 2018 the Indianapolis Colts, who hired Matt Eberflus as their defensive coordinator from Dallas, returned to the 4–3 front for the first time since 2011.

The Washington Football Team, with the hiring of Ron Rivera as their head coach, switched to the 4–3 defense in 2020.

The San Francisco 49ers, after hiring Robert Saleh as defensive coordinator in 2017, switched to the 4–3 defense after running the 3–4 for a long time.

The Minnesota Vikings have not run the 3–4 as their base since 1985.

The 3–4 defense was originally devised by Bud Wilkinson at the University of Oklahoma in the 1940s as the 5-2 Oklahoma defense. The 1972 Miami Dolphins were the first team to win a Super Bowl with the 3–4 defense, going undefeated and using number 53, Bob Matheson, as a down lineman or rushing linebacker. Matheson replaced defensive tackle Bob Heinz, shifting Manny Fernandez to nose guard.

The first NFL team to regularly employ the 3–4 was the 1974 New England Patriots under Chuck Fairbanks, who employed the 5–2 for all but one of his six seasons (1967–72) as head coach of the Oklahoma Sooners (the 1971 Sooners employed the 4–3).

In 1976, Oakland Raiders coach John Madden switched to the 3–4 after injuries decimated the team's defensive line. The Raiders went 13–1 in the regular season and defeated the Minnesota Vikings in Super Bowl XI.

When the Raiders defeated the Philadelphia Eagles in Super Bowl XV, it marked the first Super Bowl in which both teams used the 3–4 as their base defense. Also notable several years later, the Big Blue Wrecking Crew, the defensive unit for the 1986 New York Giants who won Super Bowl XXI, was a 3–4 defense and featured all-time great Lawrence Taylor at right outside linebacker and fellow Hall of Famer Harry Carson on the inside. By the mid-1990s, only a few teams used a 3–4 defense, most notably the Buffalo Bills and Pittsburgh Steelers.^[4]

Defensive line[edit]

The nose tackle and the inside linebackers, those are three guys that are very important. But when you go through it, the nose tackle is probably the single-most important guy.

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. As a consequence, many 3–4 defensive linemen begin their NFL careers as 4–3 defensive tackles, as younger players typically do not possess the size, weight, and strength to play on a 3–4 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. Ideally 3–4 DEs should weigh 285–315 pounds (129–143 kg) and be able to beat double teams by getting a push.^[5] Albert Breer noted, 'In general, ideal front-seven players in the 3–4 are bigger and need to take on and defeat blocks more often in the running game.'^[6]

The 3–4 nose tackle is considered the most physically demanding position in football.^[7] His primary responsibility is to control the 'A' gaps, the two openings between the center and guards, This is called 2 gapping. They want to get 'Knock back' by reestablishing the line of scrimmage in the opponents backfield and not get pushed back into his linebackers. If a running play comes through one of those gaps, he must make the tackle or control what is called the 'jump-through'—the guard or center who is trying to get out to the linebackers. The ideal nose tackle has to be much bigger than 4–3 DTs, weighing around 335 pounds or more. An AFC Personnel director used Ted Washington as an example of an ideal nose tackle: 'In his prime, Ted Washington was the ideal guy. He was huge, had long arms, and you couldn't budge him. He could hold off a 320-pound lineman with one hand and make the tackle with the other.'^[7]

The base position of NT is across from the opposing team's center. This location is usually referred to as zero technique. The two DEs flank the NT and line up off the offensive Tackles. The location off the offensive guard is usually referred to as 4,5, or 6 Techniques.

Linebackers[edit]

I think good coaches will coach with the personnel they have, and if you only have one (good) linebacker, you're not going to play a 3–4.

In a 3–4 defense, four linebackers (LBs) are positioned behind the defensive line. The linebacker unit is made up of two inside linebackers (ILBs) flanked by two outside linebackers (OLBs). The OLBs often line up closer to the line of scrimmage than the ILBs, but may also be positioned at the same depth or deeper in coverage than the ILBs (though this is somewhat rare).

There are two types of ILBs, the Mike (for strong side) and the Will (for weak side). The Will typically is the more athletic linebacker, who can blitz, drop into coverage, play the run, and 'spy' the quarterback.^[9] The Mike is typically the stronger and larger of the two linebackers, and is used almost like a fullback on the defense. He takes on and occupies blockers for the Will, allowing the Will to flow to the ball and make tackles.^[10]

The 3–4 also has two types of OLBs. The Joker, Jack, Buck, or Elephant is usually the primary pass rusher. Depending on the scheme, the Joker can be on either side of the defensive formation. He must be an excellent pass rusher, and has to be able to beat both stronger right tackles and rangier left tackles off the edge of the formation.^[11] The other 3–4 OLB, the Sam, does not have a specific designation. Like a Sam linebacker in a 4–3 scheme, the other 3–4 OLB must be able to cover, blitz, and play the run.

Strengths of the 3–4 include speedy ILBs and OLBs in pursuit of backs in run defense and flexibility to use multiple rushers to confuse the quarterback during passing plays without being forced into man-to-man defense on receivers. Most teams try to disrupt the offense's passing attack by rushing four defenders. In a standard 4–3 alignment, these four rushers are usually the four down linemen. But in a 3–4, the fourth rusher is usually a linebacker, though many teams use a safety to blitz and confuse the coverage, giving them more defensive options in the same 3–4 look. However, since there are four linebackers and four defensive backs, the fourth potential rusher can come from any of eight defensive positions. This is designed to confuse the quarterback's pre-snap defensive read.

A drawback of the 3–4 is that without a fourth lineman to take on the offensive blockers and close the running lanes, both the defensive linemen and the linebackers can be overwhelmed by blocking schemes in the running game. To be effective, 3–4 linebackers need their defensive line to routinely tie up a minimum of four (preferably all five) offensive linemen, freeing the linebackers to make tackles. The 3–4 linebackers must be very athletic and strong enough to shed blocks by fullbacks, tight ends, and offensive linemen to get to the running back. In most cases, 3–4 OLBs lead their teams in quarterback sacks.^[12]

Usually, teams that run a 3–4 defense look for college 'tweeners'—defensive ends that are too small to play the position in the pros and not quite fluid enough to play outside linebacker in a 4–3 defense—as their 3–4 outside linebacker. The wisdom of this strategy is demonstrated in the career of Harry Carson, who played as a defensive lineman in his college career and then went on to become a Hall of Fame ILB for the New York Giants in the 1970s and '80s. According to NFL coach Wade Phillips, 3–4 linebackers 'are a little bit cheaper, and you can find more of them,' while 'it's harder to find defensive linemen to play a 4–3 and pay for all of them.'^[13]

Secondary[edit]

The 3–4 defense generally uses four defensive backs. Two of these are safeties, and two of them are cornerbacks. A cornerback's responsibilities vary depending on the type of coverage called. Coverage is simply how the defense will be protecting against the pass. The corners will generally line up 3 to 5 yards off the line of scrimmage, generally trying to 'Jam' or interrupt the receivers route within the first 5 yards. A corner will be given one of two ways to defend the pass (with variations that result in more or less the same responsibilities): zone and man-to-man. In zone coverage, the cornerback is responsible for an area on the field. In this case, the corner must always stay downfield of whomever it is covering while still remaining in its zone. Zone is a more relaxed defensive scheme meant to provide more awareness across the defensive secondary while sacrificing tight coverage. As such, the corner in this case would be responsible for making sure nobody gets outside of him, always, or downfield of him, in cases where there is no deep safety help. In man coverage, however, the cornerback is solely responsible for the man across from him, usually the offensive player split farthest out.

The free safety is responsible for reading the offensive plays and covering deep passes. Depending on the defensive call, he may also provide run support. He is positioned 10 to 15 yards behind the line of scrimmage, toward the center of the field. He provides the last line of defense against running backs and receivers who get past the linebackers and cornerbacks. He must be a quick and smart player, capable of making tackles efficiently as well as reading the play and alerting his team of game situations.

The strong safety is usually larger than the free safety and is positioned relatively close to the line of scrimmage. He is often an integral part of the run defense, but is also responsible for defending against a pass; especially against passes to the tight-ends.

One-gap versus two-gap 3–4 systems[edit]

The 3–4 has two basic defensive variations: the one-gap and the two-gap. In a two-gap system, the linemen are charged with tying up two blockers. This allows the linebackers to 'flow downhill' and make tackles without shedding blocks.^[14] The one-gap, on the other hand, distributes the responsibility for gap coverage evenly between the linemen and linebackers. Each player has a few 'key reads' after the ball is snapped. For example, the middle linebacker may be covering the strong side A gap (gap between center and strong side guard). If he sees the guard move right, then he flows with the guard, moving more or less laterally parallel to the line of scrimmage. If the guard moves left, he attacks downhill (perpendicular to the line of scrimmage) and 'shoots his gap.' Responsibilities in the one-gap vary depending on the defense.^[15]

Very few teams use purely one or two-gap systems in today's NFL. However, the majority of teams, such as the Green Bay Packers and Pittsburgh Steelers primarily use the two-gap 3–4. The Houston Texans and Denver Broncos primarily use the one-gap 3–4. The New York Jets use a versatile, hybrid defense combining one and two-gap looks.^[16]

LANDOVER, MD - OCTOBER 11: Aaron Donald #99 of the Los Angeles Rams warms up before the game against the Washington Football Team at FedExField on October 11, 2020 in Landover, Maryland.

Since the Super Bowl debuted in the 1966 season, only one quarterback has won as a starter for two different teams. Peyton Manning accomplished the feat, guiding Indianapolis to victory in Super Bowl XLI before winning with Denver in Super Bowl 50. Tom Brady has the opportunity to join his fiercest rival when he leads the Tampa Bay Buccaneers against the Kansas City Chiefs in the 2021 Super Bowl on Sunday. Kickoff from Raymond James Stadium in Tampa, Fla. is scheduled for 6:30 p.m. ET.

Brady won six championships with New England before joining Tampa Bay (14-5), which recorded a 31-26 victory at Green Bay in the NFC Championship Game to secure its first Super Bowl appearance since 2002. The Chiefs (16-2) have the chance to become the eighth different team to repeat as champion after beating Buffalo in the AFC title game. Kansas City is a three-point favorite in the latest Chiefs vs. Buccaneers odds from William Hill Sportsbook, while the over-under has dropped to 56.

Why the Chiefs can cover

Facing a team with a quarterback who is seeking his seventh Super Bowl title in his 10th appearance may seem daunting, but Patrick Mahomes has proven to be unflappable. The 25-year-old already is about to complete just his third NFL season and already has been named league MVP, won a championship and claimed Super Bowl MVP honors. Mahomes had a strong regular season, throwing for 4,740 yards and 38 touchdowns to finish second and fourth, respectively.

Mahomes has one of the top wideouts in the NFL in Tyreek Hill at his disposal and could get back the services of receiver Sammy Watkins, who hasn't played since Week 16 due to a calf injury. Mahomes has also formed a dangerous connection with tight end Travis Kelce, who has 21 catches for 227 yards and three touchdowns this postseason.

Why the Buccaneers can cover

With nine previous Super Bowl appearances, it's no surprise that Brady owns a number of the event's all-time records. The 43-year-old has amassed 2,838 passing yards, 18 touchdown tosses and owns the top two single-game yardage totals (505 in Super Bowl LII, 466 in Super Bowl LI). Brady will join Manning, Craig Morton and Kurt Warner as the only quarterbacks to start a Super Bowl for two different teams and can become the first to record a victory in three separate decades.

Run Line Nfl Game

Brady has spread the wealth this postseason, throwing touchdown passes to six different players. Mike Evans, who was fourth in the NFL with a career-high 13 scoring receptions during the regular season, is the only member of the Buccaneers with multiple TD catches (two) and one of four to reach double-digit receptions (10).

Fellow wideout Chris Godwin leads Tampa Bay with 223 receiving yards and is tied for most catches (14) with running back Leonard Fournette, who has hauled in a TD pass while also running for 211 yards and a pair of scores.

How to make Chiefs vs. Buccaneers picks
