How to Use “Backside Tags” to Attack the Entire Field in the Passing Game

This article is by my friend Dan Gonzalez, who, in addition to being an expert on offense and the passing game, has written a book about both called Concept Passing: Teaching the Modern Passing Game. Dan also previously collaborated with me on an article about the four verticals pass concept. I am honored to host his excellent article on Smart Football.

“Pick a side.” This common coaching directive, in which the quarterback is given the autonomy to choose his starting point on a pass play, has always bothered me. It’s an abdication of a coach’s responsibility: It’s the coach’s job to orchestrate the assault on a defense –- why isn’t the quarterback given a specific starting point and a full complement of options? Even as a college player, I would sit in meetings or pick up a game plan handout and roll my eyes when I saw these words attached to a pass play. My coaches were no slouches – there was an NFL pedigree throughout the staff, and they were fresh from coaching the first pick in the NFL draft when they came to my school. We were taught sound mechanics and fundamentals and our system was a complex pro-style system. Still, there was an abundance of mirrored pass patterns (see Diagram 1 below) in our system, where receivers on both sides of the formation ran the same routes. While these plays were sold as attacking the full field, I often thought to myself, “If everyone comes open at the same time, aren’t we really wasting half the field, and sometimes more than half of the eligible receivers?”

Diagram 1. Example of a “mirrored” pass pattern

I have always considered myself a sort of “free thinker” when it came to football. My talent would never have allowed for me to dream of playing after college (I considered myself blessed to be there), and I always knew I would go into coaching. When I studied our game tapes (I was in charge of the passing game quality control as a senior) and opponent scouting tapes, I was not only living in the “now” — I was also searching for the methodology that I would use when I finally got to run my own offense. Even then, there were two things I knew I wanted: (1) My system would establish itself with the dropback pass and (2) I was going to give the quarterback as many options as possible on a given pass play.

In the passing system I have coached myself (and have since installed for my clients on a consultant basis), pass plays have “frontside” and “backside” component. They fit together through a system of pattern variations, or “tags,” which I’ve created to give the quarterback a well defined method of attacking the full width and depth of pass defenses. There are three types of backside tags, each encompassing a specific way to affect the backside of a pass defense:

  • Provide outlets if the primary combination is covered.
  • Control safety rotation or displacement.
  • Prevent “matching” of the undercoverage.

For this article, I’m going to share a little of the thinking that goes into the first category of backside tags that we teach –- in our vernacular, these combinations are called “Scan Reads.”

Four verticals is the best, Tim Tebow vs. the Vikings edition

Especially if the defense plays Cover 2 and is terrible at it:

The double smash pass concept with the runningback deep down the middle

One of the great all-time pass concepts is the “smash” concept, which I’ve previously discussed at length. In the concept, the outside receiver hitches up at five yards while an inside receiver runs a ten-to-twelve yard corner route over the top. This creates a “vertical stretch” on the corner, which is particularly potent against a two-deep Cover Two defense.

The smash is probably best installed with some kind of routes on the backside that attack the middle of the field, that way to keep the safety from overplaying the corner route. Many teams, however, teach the smash to both sides as a “mirrored” concept. This is good, but the problem can come when both safeties overplay the corner route.

But there is a counter. If a team’s safeties overplay the corner route on the smash, you hit them inside. You can have the outside receiver run a delay route back underneath and then upfield underneath the safety, but even better is simply to send someone unexpected into the vacated area: the runningback.

In the example, you can see Oklahoma State call this against a two-deep shell run by Texas A&M. They had overplayed the corner routes, so the variation was simple: throw it deep down the middle to the back in the vacated area. Were Texas A&M to have shown a blitz the quarterback would have checked out of the play (as there were only five protectors), but so long as they got a base two-deep look, the play was there. You can see the result in the video below, after the jump.

Breaking down Bill Walsh’s “drive” concept with Miami OC Jedd Fisch

Hat tip:

If you want more detail into Walsh’s “drive” concept, read more about it here. (Also see here for more detail on the “smash” concept Fisch shows on the backside.) Lastly, Fisch has already shown that a lot of his passing game is built on putting different concepts or “beaters” to each side; for more on that idea, see here and here.

Snag, stick, and the importance of triangles (yes, triangles) in the passing game

When Sid Gillman revolutionized and all but invented the modern passing game, he did it through a “conceptual” approach to pass plays based on three “pass concepts”. Because football is governed by its immutable twins of strategy — arithmetic and geometry — these remain the foundation for all effective pass plays:

Simple stuff

  1. Vertical stretches — These place two or three receivers at different levels vertically up the field to “stretch” the defense. Examples include the smash concept and the frontside flood concept (see here for a diagram and here for  a video). Another name for these are high/low or hi/lo reads.
  2. Horizontal stretches — These place two, three, four, or five receivers horizontally across the field or a portion of it to “stretch” defenders from left to right or right to left (or inside to out or outside to in). Examples include all-curl.
  3. Man or “object receiver” reads — These are not necessarily distinct from the above horizontal and vertical stretches, but the focus is on having a route or combination of routes that will defeat man-to-man coverage. Examples include the mesh concept from the Airraid, bunch passes and option-routes.

These three categories essentially made up the full panoply of choices for the passing game for, well, for a really long time. But at some point — most notably with Bill Walsh’s 49ers — a “new” concept began emerging, though it wasn’t actually new at all but was instead a very clever twist on what Gillman had synthesized. Walsh realized that you could combine the horizontal and the vertical stretch to create a kind of “new” stretch, though one made up of both of Gillman’s first two categories. Moreover, Walsh often combined the two zone beaters — the horizontal and vertical stretch — with the third category, the man beating concept, into a single “triangle” read that also was designed to defeat man coverage. If the perfect pass play was the Holy Grail of modern football, then the triangle is its best personification to date and Walsh its Galahad.

But let’s take a step back to understand why the triangle stretch works, along with its negatives. The best vertical or horizontal stretches use more than two receivers, with three or more receivers being used in various “zone flood” routes. If you caught the defense in the right look it was mathematically impossible for them to defend you: If you ran the three-level flood route against Cover 2, they had two guys (a corner and a safety) to defend three receivers; and if you caught a Cover 3/4-under defense with your all-curl concept, it was easy pick’ins:

All this has been detailed before, and if you can identify what coverage you are facing it is still better to run a true three-level vertical stretch or five-receiver horizontal stretch against the right coverage — if you get that right, there’s very little the defense can do. But, of course, it’s not so easy to figure out what coverage the defense is in before the play; indeed, with the advent of combo coverages and pre- and post-snap shifts, it’s often is difficult to even determine what the coverage was even after the play.

Enter the triangle stretch. The insight behind the triangle is that the horizontal and the vertical stretch are combined to create a single straightforward read for the quarterback that provides answers no matter what the defense presents.

All of the major “new” (in relative terms) passing concepts are based on a triangle read. The weakness of the triangle stretch is that it’s typically only possible to only get a two-man horizontal or vertical stretch, whereas with a true “flood” you can place three (or more) receivers across the field on a given plane to truly defeat a defense. This limitation means that a triangle can be throttled by certain coverages that rotate to the triangle side.

Tim Brown was a true technician at wide receiver

Watch this video and marvel at what an amazing job he does defeating the technique of each defender on him. He uses specific techniques against man and zone. By NFL standards he wasn’t an unbelievable athlete, but he didn’t need to. This is how you put up over 1,000 yards and nine touchdowns at age 35 (and over 900 yards at age 36).

Follow-pivot pass concept

Good stuff from Coach Hoover’s site:

I first learned this play while studying the Meyer/Mullen Florida Gator Offense. I remember sitting at their first Spring Clinic, listening to Dan Mullen talk. Mullen explained that their offense mainly used five passing concepts: All-Go [Ed.: See also this article.], Smash, Houston (maybe another article in the future), H-Option, and Follow-Pivot.

[Ed. Note: Urban Meyer and Dan Mullen got this play (among others) from Joe Tiller at Purdue. Check out pages 131 to 133 (in PDF page numbers, not playbook page numbers, of the 1999 (Drew Brees) Purdue playbook.]

After studying the Follow-Pivot concept, I realized that it was very similar to the NCAA pass (Post-Dig-Drag). However, because of the distribution of routes, this concept is better suited to beat Quarters coverage. . . .

Conceptually, the play creates a High-Low on the Free Safety, as well as [a] Middle-Triangle [read] off the two weak-side Linebackers (or weak-side and middle LBs). I always put the Post to the boundary, and have the Follow route coming from the field. I do this because teams will almost always rotate their coverage to the field (which would disrupt my Triangle) or because we see a lot of Quarters with the Strong Safety inside my #2 receiver to the field (which makes it difficult for that receiver to run the Post). I must create a situation where I can isolate the Free Safety for my High-Low read, and my Post and Follow routes can win.

pivot

The two receivers closest to the ball will run Pivot routes if displaced or Check-down/Breakout routes from the backfield. Their purpose is to attract the two LBs closest to the Post, or replace those LBs if they disappear in coverage or become pass rushers. Those two LBs are also the players that we are trying to occupy get the Follow route open. A coaching point that we teach to the Pivot & Check-down routes is to have them sit and replace the LB they are aiming for if he rushes the QB or drops into coverage. They will only work outside if they are covered, as this will open up a huge throwing lane over the middle for the Follow route. Finally, the outside receiver to the field runs a Curl, and is there should the QB have to scramble that way.

Check out the video cutup and read the whole thing. This is a good complement to the shallow cross concept I recently described.

Bobby Petrino’s shallow cross concept – concepts, routes, and protection

The shallow cross is, quite possibly, the best pass play in football: Almost any quarterback can complete it; almost any receiver can run it (though there is more nuance than maybe one might initially realize to a good shallow route); it is a way to get “speed in space” without requiring a big arm; it works against most all coverages; and throwing a few of these tends to open up big plays downfield as defenders creep up.

Score... heh heh heh...score...

I’ve discussed lots of variants of the shallow, but one of my favorites remains Bobby Petrino’s. I see Petrino’s version as essentially the meshing of a pro style approach with a college sensibility; the reads are simple but there are nuances built in so that it works against almost any coverage. Petrino moves his guys around a bit, but, the key feature is that unlike the Airraid guys, he has his runningback and his shallow going to the same side: the back runs a wheel route to pull the underneath coverage to the sideline and up the sideline, while the other two receivers run a post and a square-in, and on the backside the receiver runs a comeback. The base play looks like this:

 

shallow

The post and the wheel are “alert” routes, in that they aren’t part of the basic reads but the quarterback can look at them first if the defense gives it. The most famous example of hitting the wheel was the second play of the game last season against Alabama. Alabama came out in a quarters or split safety look, but there was some coverage bust (it’s hard to say exactly but it was probably the cornerback chasing the post route all the way inside, as shown in the video below).

More typically, the goal is to hit the shallow, as the read is shallow to square-in to comeback on the backside. (Note that some people have said all routes should be read high to low, including the shallow. Although I think that’s a good rule of thumb, that’s all it is: the shallow needs to be the read before the square-in.) Below is a diagram and clip of the same concept, except Petrino now has the square-in/dig and the shallow coming from the same side.

shallow

Here, Arkansas runs the shallow and the wheel to the short and tight side (short side of the field and where there is only a tight-end). The corner and safety drop deep, and the advantage of running the shallow to this side is the tight alignment brings the linebackers in, and the shallow ends up able to outflank those guys.

The read is the same though: Alert (post/wheel), shallow to square-in to comeback. I’ve covered all of this previously, but it’s worth mentioning again because don’t take my word for it: Ryan Mallett explained it all to Jon Gruden recently. Jump to the 2:05 mark. (My favorite part of this is when Mallett begins discussing the hot reads and Gruden’s eyes light up.)

Packaging three-step and five-step passing concepts into the same play

Modern defenses are very, very good. Too good, in fact, for successful offenses to expect to be able to simply call some traditional play in the huddle — ye olde 24 Blast or 42 Boot Pass — and be able to simply line up and run it with any hope of sustained success. Not only are defenses sound, defensive coordinators and talented defenders have become masters of deception, and the game has increasingly become a mental as well as physical struggle.

I would've liked this concept

Fortunately, defenses aren’t yet — due to the immutable laws of arithmetic and geometry which apply with equal force on a football field — magical, meaning that all defenses always have weaknesses. The trick is to find them and, as Spurrier says, to put your kids in position to win. The goal is to try to tilt the advantage back to offenses. There are essentially three strategies:

  1. Line up in a formation and let a coach or a quarterback change the play. You see this whenever Peyton Manning or some other NFL guy audibles at the line (though his options have usually been narrowed to two or three before the snap), or when a no-huddle team lines up and looks to the sideline for guidance. The idea is that, while it is still pre-snap and the defense can still move, it has given away certian clues, including personnel and general structure.
  2. Use multiple formations and motions to confuse the defense or gain an advantage in numbers or leverage. This approach tries to turn the defense against itself by never giving the defense a chance to get settled or to identify what the offense may do. Moreover, sometimes the defense simply fails to adjust, and the offense gains some new advantage. The downside of this approach is it leaves little time and fewer clues for the offense to make adjustments, but the idea is that “motion causes emotion” (to use the old adage) and the offense has an advantage in that it knows where it is going. This is the method employed by Boise State.
  3. Give your players options on their assignments for after the snap. Just as it sounds, this is the principal governing all “option”-esque attacks. The macro idea here, pioneered by Tiger Ellison, is that backyard football is not played in a static, overly orchestrated way, and instead the natural inclination of kids to run around and make decisions on the fly — and so should it be in real football. This can manifest itself in different ways, from the triple option to the spread option to the passing game. Each play provides a superstructure but freedom within it. The idea is you don’t need much else, except for the players to begin adapting and making the rights reads. As said in Remember the Titans, “I run six plays. Split veer. It’s like Novocain. Give it time. It always works.”

A few years ago, it was possible to achieve unheard of success by designing a new play, or sometimes simply by joining the bandwagon and going spread, especially if you had better athletes. Now, the innovations are ones of communication and organization; much of the talk this season centered around Oregon’s fast-paced no-huddle, particularly its fascinating playcalling system. For now, most of the biggest schematic ideas have been hashed out and the question now is how to make it all work together. Packaging pass concepts together — i.e. putting different pass concepts, each designed to beat particular pass coverages or families of pass coverages, to each side of the play — is not new. But it is limited in its own way (more on those limits in a moment), and there are ways to incorporate more of the above ideas into a single concept. Moreover, when done correctly, it’s possible to continue to be multifariously (and deceptively) simple, by using the same handful of pass concepts in new ways.

Problems with the traditional approach of packaging pass concepts. Almost any coach trying to call a pass play, face buried in the Denny’s menu of the playcall sheet, is forced to answer that age old question: Will it be Cover 3 or Cover 2? (Or Cover 4 or man or a blitz, and so on.) The problem is that, no matter how good your pass it is, due to the particular horizontal or vertical stretch it uses, each pass play is better against certain coverages than others. At most, a play might be good against two defensive concepts, and certain plays — like snag — are handy utility plays to get completions against most coverages but that doesn’t mean that they literally work against everything. One potential solution is to “package” different concepts to each side, again with the traditional way being to put a “Cover 3 beater” to one side and a “Cover 2 beater” to the other. (If you want a refresher on basic pass coverages, check out this piece.)

Three problems, however, quickly present themselves with this simplistic answer:

  1. The quarterback only reads half the field, determined based solely on the alignment and movement of a couple of defenders. If the quarterback is either wrong or the receivers fail to get open, the play is essentially a bust.
  2. The side the quarterback throws to is usually determined based on the safeties (or sometimes the middle linebacker). It does not take into account blitzes. It’s possible to include anti-blitz solutions too, but this becomes yet a third read — that might be inconclusive.
  3. Typically, the pass concepts put to each side are effective against those defensive concepts, but they typically do a poor job of dealing with interior or floating defenders, who can turn a quarterback’s good read into an interception. Relatedly, the pass concept may not work at all against combination coverages or roll coverages, which can give false keys.

The third point is worth elaborating on briefly. Shown below is a typical “packaged” five-step drop combination: the curl/flat combination to one side with the smash or corner/flat combination to the other.

This play should work, as the quarterback ought to see that the defense only has one single safety and he thus looks to the left side, with the curl/flat combination. But the packaged pass concepts don’t do anything to control those interior players. The same would be the case if the defense lined up with two deep safeties and he worked the smash side, to his right. There are ways to solve this problem, but there’s an approach that solves (or at least greatly improves upon) all three issues raised above.

Three-step and five-step, together. The idea for this solution came from two sources: the old run and shoot “Read” play and the book, Concept Passing,” where Dan Gonzalez describes something similar. The broad idea is to achieve multiple things in one play-call, but to sequence it so that it all can actually be done by a high school or college kid. The run and shoot “read route” put a “quick” or three-step-esque (remember that the run and shoot used half-rollouts) to one side, while putting the old favorite, the “switch” to the backside. See below:

Against any kind of blitz or tight-man, the quarterback would deliver the ball to one of the outside receivers (typically the slot running to the flat) off his third-step. If the defense covered that, he would finish his drop, step up, and read the two backside receivers running the old switch, which was just a form of the “seam read” from four verticals but where the two receivers criss-crossed at the snap. In his book, Gonzalez describes a more pro-style application; here is my take on it.

Running and throwing the fade route against press coverage

This past weekend saw that old classic, the fade route, used to win a couple huge games in the SEC: The game winner in the LSU-Florida game was a fade (the second try), and South Carolina’s Alshon Jeffrey caught several big time fade passes against formerly #1 Alabama.


As simple as it seems — “Run out there and I’ll throw it up” — it’s a surprisingly subtle play, and is often taught improperly. Steve Spurrier, of course, is one of the masters of the fade, and this is not the first time LSU has won a big game on a well-thrown fade.

The first problem is the name, “fade.” This conjures up the idea that the receiver’s job is to release off the ball and immediately start “fading” to the sideline, where the quarterback has to throw it to an increasingly vanishing spot between the defender and the sideline. This is wrong.

1. The route, at least from the receiver’s perspective, should be thought of as an almost totally vertical route. Against press man coverage, he should get the defender’s feet moving; the goal is not to get “around” the defender but to get through him, by making the defender move and then having the receiver run on a path immediately past him. This isn’t always possible, and the fade is an outside release play, but that should be the goal every time it is called. Too often young receivers want to outside release, get jammed, and can barely get off the line of scrimmage or get run basically out of bounds.

2. Second, the receiver must leave at least six to seven yards between him and the sidelines. Some teach five yards but I prefer seven, because it leaves more margin for error. A simple way to think about it is to tell the receiver to get no wider than a yard outside the numbers (i.e. the big numbers on the field between the hashmarks and the sideline).

3. Third, consistent with the above two points, the receiver should actually try to lean into the defender as he bursts upfield. As I’ve said previously:
