The 43 Under Defense Part 2: The Leo Defense
NOSE GUARD
The Leo variant of the 43 Under is much more like a traditional 34 Nose Guard than the Tampa 2 Nose. Typically the Leo Nose will line up over the Offensive Center and plays both A Gaps as a traditional Nose Guard would. While the "Tilted" Nose of the Tampa 2 is a quicker, penetrating Tackle, the traditional Nose Guard is usually a huge space eater with wild man strength and lateral agility. His job is to hold down both Gaps and close down on the Running Back if he goes through either of them. The Nose will also eat up a double team to keep the Offensive Line from getting to the Linebackers at the second level. It should be noted that the Nose in a Leo defense will also play some 1 Gap and hold, where he is playing 1 Gap like a 2 Gap. Instead of penetrating like normal 1 Gap defense, he is merely positioning himself in the Gap in an attempt to seal up any holes for the Running Back.
3 TECH
Just like the Tampa 2, the Leo variant has an Under Tackler or 3 Tech playing between the Guard and Tackle. Unlike the Tampa 2 however, the Leo 3 Techs do a lot more 1 Gap and holding than straight penetrating and are usually a little larger than their Tampa 2 brethren. They occasionally will even play 2 Gap like a Nose Guard.
5 TECH
In the Leo defense the Defensive End will be a much bigger player, more like a typical 34 end. He may line up in the 5 Tech and control that gap, similarly to the Tampa 2. A lot of the time however, this end will play in a 4 Tech and be head to head with the Offensive Tackle. If he lines up in the 4 Tech he will usually play both gaps on either side of Offensive Tackle. Both defenses also have their strong side Outside Linebacker lined up outside of the 5 Tech End. The difference between the two is more emphasis is put on pass coverage by this linebacker in the Tampa 2 and more emphasis is put on run stopping in the Leo.
WEAK END
On the Weak side both the Tampa 2 and Leo defense have their best outside speed rushing Defensive End lined up outside of the Offensive Tackle. The Leo defense will usually have their weak side end lined up much wider than a normal 43, in almost a Wide 9 alignment. The Wide 9 alignment is essentially the outside shoulder of an (imaginary in this case) Tight End. The Leo is the glamour position and is the one guy who is not primarily focused on suffocating the run, rather the Leo's only focus is on sacking the Quarterback. The Leo is usually a hybrid player, who is smaller than a normal 43 end but lacks the coverage ability to be a 34 Linebacker. They can (and will) line up in a normal 3-point stance, a Linebacker's 2-point stance, or in either of these two stances, but tilted inward for a better launch angle.
LINEBACKERS
Despite having the same type of players who play Linebacker in the Leo as in Tampa 2 they are much more run focused, usually reading the pass second. While the Leo will occasionally bring in a speed rusher for the Sam Linebacker to go with a pseudo 34 look, they usually have 3 fast linebackers just like the Tampa 2. The Strongside or Sam Linebacker will usually have outside contain with the Mike(Middle) and Will(Weakside) backers having the the two A Gaps. The Strong Safety will often play up like a Linebacker and provide backup to Sam.
COVERAGE/SECONDARY
When looking at the coverage in the Leo defense, you have to look at Seattle and two they run the scheme. In Seattle, they run a hybrid 3 Deep/Single High coverage. Seattle likes to bring their Strong Safety up into the box to give an almost 44 look. Out of the base Under front they will have their Strong Safety and Will Linebacker cover the short outside of the field while the Sam and Mike backers cover the short inside of the field. If they are playing a true Single High Cover 1 then they will have their two Corners jam the receiver at the line and cover the flats. If they are playing 3 Deep then the Corners will jam the receivers and then run with them to fill in the deep outside of the field while the single high Free Safety will play the deep middle of the field. Both of these coverages put the Linebackers and Strong Safety in position to stop both the short pass and the run, using their speed and vision. It also puts the Corners in position to give support against the run and lets their Free Safety roam the deep field. While they do not always press, and will blitz or play man to man, these are the base coverage shells the Seahawks like to run when playing zone.
CONCLUSION
These defenses, for all their differences have quite a few things in common. They both work best when they have aggressive and smart Corners who know when to play the pass and when to play the run. They both utilize three deep coverage shells a good deal, and prefer to get after the Quarterback without having to blitz. And they both demand athletic Linebackers who can swarm to the ball quickly in the run game while covering their zones in the pass game. Both also blur the line between Linebacker and Safety. The Tampa 2 does this with a Mike Linebacker who is essentially a third safety, along with two fast and athletic Outside Linebackers. The Leo defense does this by having fast athletic Linebackers and a big Strong Safety who plays in the box almost as often as the Linebackers do. All in all they are both very strong defenses, and I personally would love to see a team that could combine the two, as they have enough in common personnel wise that a combination of these two could work well.

The 43 Under Defense Part 1: Tampa 2
In my previous post about the 34 Defense I talked about the 1 Gap 34 defense briefly. This defense is a hybrid of the 34 and 43 defenses, implementing certain concepts from both. I decided I would look at another hybrid defense, the 43 Under. While there isn't really a full 2 Gap 43 the way that there is a full 1 Gap 34, the 43 Under has some 2 Gap elements mixed with 1 Gap elements.
Their are two main types of 43 Under Defenses, the Tampa 2 Variant and The Elephant/Leo Variant(referred to from here on as the Leo Variant).
The Tampa 2 version was originally a pure 1 Gap 43 Defense, but some teams have mixed in some 2 Gap elements, mainly at the Nose Guard position.
NOSE GUARD
Like a 34 Defense the 43 Under has a Nose Guard, however how much like a 34 Nose Guard this player is depends on the scheme. In the original Tampa 2 the Nose Guard was a "Tilted" Nose Guard. This position, who's invention is often credited to "Mean" Joe Green, has the Nose Guard line up as a 1 Tech between the Center and weak side Guard, and then turn on a slight angle towards the Center. This gives the Nose better leverage and a easier path to attack and shoot through the A Gap. Some Tampa 2 teams have put in plays or even ran their base defense with a 2 Gap Nose Guard who plays much like a 34 Nose would.
3 TECH
In Both the Tampa 2 and the Leo variants the second Defensive Tackle is a more traditional 43 defensive player. Known as either the Under Tackle or the 3 Tech, this Defensive Tackle plays in the 3 Technique between the weak side Guard and Tackle. The 3 Tech in a Tampa 2 is usually a smaller more athletic Defensive Tackle who excels at penetrating through the B Gap and wreaking havoc in the backfield.
5 TECH
In the Tampa 2 the strong side Defensive End will line up in a 5 Tech, on the outside shoulder of the Strong Tackle and shoot through that gap. This player will be a traditional 43 style Defensive end who's main goal is to sack the Quarterback. Nonetheless he will play the run on the way to the Quarterback, and tackle anything that comes through the strong side C Gap.
WEAK END
On the Weak side both the Tampa 2 and Leo defense have their best outside speed rushing Defensive End lined up outside of the Offensive Tackle. The Tampa 2 Weak Defensive End is usually a standard 43 pass rusher. Very athletic and quick, but strong enough to Bull Rush an Offensive Tackle. These guys will occasionally be asked to drop into the flat on Zone Blitzes or max coverage situations, so they must have the athletic ability and mental awareness to drop into coverage from time to time.
LINEBACKERS
One thing that both defenses have in common is the type of Linebackers who play in these defenses. The Tampa 2 defense employ much faster Linebackers who are asked to read and react quickly and swarm the football. These Tampa 2 Linebackers are asked to read the pass first, but as soon as they read run must swarm to the ball carrier. This is absolutely necessary, as the Tampa 2's Defensive Linemen are usually much to far into the backfield to be of use on plays such as delayed handoffs or on runs where the ball carrier can get to the second level.
COVERAGE/SECONDARY
The Tampa 2 runs a Cover 2/Cover 3 hybrid, where instead of two deep corners and a safety they use two deep safeties and the Mike Linebacker. The Free and Strong Safeties will each cover the deep outside of the field, with the Corners often pressing and getting physical at the LOS and being in position to shut down screens and outside runs. The two outside backers will then split the short field while the Mike Linebacker drops into the deep middle, playing like a traditional single high safety. The Mike Linebacker has to be an extreme athlete here as he must cover 10-15 yards of space in this coverage. He must also have good judgment too as he cannot get sucked in by a Play Action pass or the deep middle will be wide open. Similarly he cannot be victimized by a draw play or he could be 15 yards off the ball when the handoff occurs, leaving the defense short in the middle. The saving grace here is that the two Corners play close enough up that they may be able to make up for an absent Mike backer.
Stay tuned for part two where I look into and compare the Tampa 2 to Seattle's Leo defense.

34 defense
In honor of this years super bowl I will be going over a scheme that both super bowl teams run, the 3-4 defense. The 3-4 defense is generally accredited to Bud Wilkinson of the University of Oklahoma and is believed to have been created around 1940. The 3-4 is basically the old school "Fifty defense" which is a 5-2 alignment. I will also compare and contrast the differences between the 3-4 and the other most popular defense these days, the 4-3.
The first main difference of the 34 and the 43 is the personnel on the field. Instead of having 4, smaller quicker defensive lineman such as in the 43 you have 3 quite large stronger defensive lineman. There is also more of a focus on strong tacklers in a 34 defense and your outside linebackers traditionally would be larger than in a 43 as they will be blitzing and regularly going up against offensive tackles. Also 43 defenses generally have linebackers who are quicker and better in coverage, all the way to the extreme Tampa 2 defense in which the Mike or Middle Linebacker would be essentially a third safety.
Their are a few variations on the 34. I will be going over three in this article.You have the more classic 34 that the Patriots ran all the way to three super bowl victories which includes massive two gapping defensive lineman and oversized pass rushing outside linebackers. The defensive line concept is for the three lineman to each take on double teams with the Nose Guard lining up head up on the center and taking each A-Gap (the gap on either side of the center between the center and the guards), and the two Ends lining up over the tackles and taking the B(in between guard and tackle) and C-Gaps (in between tackle and tight end). The two outside linebackers, Sam (strong side) and Will (weak side) would have outside contain, taking anything outside of the tight end in the Patriots base defense. The inside linebackers were generally balanced linebackers who could tackle as well as drop into coverage. This is a very balanced defense that excels against the run and can get pressure on the QB with the right personnel.
Nose Guard Example: Ted Washington, Vince Wilfork, Kyle Love
Defensive End Example: Richard Seymour, Ty Warren, Vince Wilfork (He has played End recently with Kyle Love playing Nose Guard)
Outside Linebacker Example: Mike Vrabel, Willie McGinest
Inside Linebacker Example: Tedy Brushchi, Brandon Spikes
The other older version is the one ran by Dick LeBeau in Pittsburgh. It is much closer to the old school 50 defense as the outside linebackers are more like stand up defensive ends than actual linebackers. Where the Patriots linebackers were bigger and better at blitzing the Steelers linebackers are basically defensive lineman. They will drop into coverage but they generally only do so on special Zone Blitzes where they drop into a zone vacated by another linebacker blitzing. The defensive line also runs a two gap technique just like the Patriots however in the base defense LeBeau lines up his end on the widest man on the line with Sam and Will lined up just outside of the Ends. The inside linebackers usually shift over a little to the weak side and the Strong Safety playing as a 5th linebacker. This is why LeBeau prefers run supporting safeties who are more focused on stopping the run than playing deep coverage. The defenses main strengths are it's ability to stop the run and get good pressure on the QB because of the misdirection caused by dropping linebackers and 300 lbs lineman into coverage while blitzing safeties and interior linebackers.
Nose Guard Example: Casey Hampton, Chris Hoke
Defensive End Example: Brett Keisel, Ziggy Hood
Outside Linebacker Example: James Harrison, LaMarr Woodley
Inside Linebacker Example: Larry Foote, Lawrence Timmons
The last variation is the variation of the 34 that is becoming more and more popular is the Phillips 34. This is the defense run by the Texans currently and is the pet project of Wade Phillips. I have a little bit of personal experience with this type of defense as my high school team ran this defense this past season. It's a one gapping 34 unlike the Steelers and Patriots two gap variations. Wade relies on much smaller defensive lineman with his Nose Guards being closer to 43 defensive tackles as they weigh in around 300 lbs, much less than your typical Nose Guards. His defensive ends are closer to pass rushing defensive tackles or 43 defensive ends. Because it is a one gap scheme the Nose Guard lines up in the strong side A-Gap and shuts down anything that comes through there. The strong side end lines up in the C-Gap and penetrates through their with weak end lining up in the B-Gap and penetrating there. The designated rush linebacker lines up on the weak side outside of the offensive tackle and the Sam linebacker will line up outside the tight end. Generally the Will linebacker is a stand up defensive end type while the Sam linebacker is more balanced and can cover a TE if he has too. This has proved as late to be the most successful of the three types I have gone over as it gets massive amounts of pass rush from the inside and outside and can also stuff the run effectively by swarming to the ball.
Nose Guard Example: Jay Ratliff, Shaun Cody
Defensive End Example: Antonio Smith, J.J. Watt
Sam Linebacker Example: Connor Barwin, Anthony Spencer
Will Linebacker Example: Whitney Mercilus, Demarcus Ware, Mario Williams
All in all the 34 defense is becoming better than the 43 because of it's versatility and the ability to find good outside linebackers easier than good defensive ends.

Introduction
Welcome to Chalk Dust, a No Nonsense Football blog. This blog is going to be all about the
schematics of football, the "X's and O's" of the game. From the true dinosaurs of the game such as the 70 defense and the single wing to the en vogue schemes such as the amoeba defense and pistol offense I'll be covering it all here.
Just as my NNF blog has tried to use common sense and get rid of all of the nonsense that talking heads on ESPN and NFL Network use. Despite a good amount of my predictions not coming true this year(still don't know what I was thinking with the Denard Robinson Heisman pick) my no nonsense approach to football has served me well and Chalk Dust will continue to use this approach.
