The quarterback position is perhaps the hardest to play – and coach – in all sports. Few players have mastered the position, and even fewer coaches have mastered the art of finding, teaching, and producing quarterbacks who succeed at the NFL level.

Bill Walsh and Jim Harbaugh are two such coaches. Bill Walsh has produced Hall of Fame NFL quarterbacks as a head coach (Joe Montana, Steve Young), but also maximized the potential of several quarterbacks as an assistant coach in the NFL and as a head coach in college (Virgil Carter, Ken Anderson, Guy Benjamin, Steve Dils). Jim Harbaugh has, in his short career, produced NFL quarterbacks at both of his college stops, turning University of San Diego’s lightly recruited Josh Johnson into an NFL quarterback, recruiting to Stanford and producing star NFL quarterback Andrew Luck, resurrecting the career of Alex Smith of the 49ers, and channeling the raw potential of Colin Kaepernick into a rising star.

Both coaches emphasize the importance of fundamentals. Rather than expand into complex drills and arm mechanics, they ask their quarterbacks to master basic drills. Once mastery is achieved, the quarterbacks continue to work on the same fundamentals in order to maintain their skill in a constant search for perfection. This mastery breeds confidence, and confidence is essential for the position.

Lost intricacies of the run game: tackle trap

The trend towards pass first offensive football has generally led to a decrease in run game intricacy. Spread and pass first teams have found that they can put up high point totals with only a few simple run blocking schemes. This approach is sound – with focus on the passing game, the simplified run game means that high levels of execution can be attained on the few blocking schemes that are in the playbook.

This does mean that some concepts of the past have been largely lost. The following play exemplifies the lost art of the complex run game, a tackle trap on a top nose guard (Tony Casillas), intended to make that nose guard’s life difficult while opening a sizeable hole and utilizing angles across the line of scrimmage.

The blocking scheme: Right tackle blocks down on star MLB Brian Bosworth. Right guard pulls and looks for work. Center posts on star nose guard Tony Casillas, then walls off the defensive tackle. Left guard goes for the other MLB. The left tackle pulls and traps Casillas, while the fullback walls the other defensive tackle to the outside.

The blocking scheme: TE walls off the outside. Right tackle blocks down on star MLB Brian Bosworth. Right guard pulls and looks for work downfield. Center posts on star nose guard Tony Casillas, then walls off the defensive tackle. Left guard goes for the other MLB. The left tackle pulls and traps Casillas, while the fullback walls the other defensive tackle to the outside.

The blocks take advantage of angles, including the smashing trap on Casillas.

Casillas is sent to the turf as running back Jacque Robinson (father of NBA star Nate) exploits a wide running lane.

Robinson is untouched into the defensive backfield.

Robinson finally faces impact at the goalline.

Often, the best offensive system is the one that goes against contemporary trends. Increasingly, teams are finding that the spread offense is not a magic bullet. While the many variations of the spread ARE sound football, defenses are now built to stop them, and those offenses lack the novelty that once made them so difficult to defend.

Perhaps those defenses – built to stop the spread passing game and various zone running schemes – are now susceptible to a return to power running. The Stanford Cardinal under Jim Harbaugh and David Shaw, as well as the San Francisco 49ers under Harbaugh, have capitalized by building swift, powerful lines and incorporating complex run schemes and jumbo personnel packages. Once a staple, those schemes are now the novelty while the spread offense thrives. While mastering the execution of a run game complete with powers and counters and traps and whams and isolations can be difficult, it is more than possible with proper commitment.

Differentiating the “read option” from the veer scheme

“Read option” is one of the most overused terms in football. From commentators to sideline reporters to sportswriters, a myriad of plays are lumped together and mislabeled “read option.”

In reality, every option is a “read” option. The quarterback always reads an unblocked defender or defenders to determine whether to give the ball, keep it, or pitch it.

Still, the “read option” has become synonymous with shotgun, spread option football. The play that epitomized the spread option running game is what most coaches call the “zone read.” The key feature of this play is that the offensive line zone blocks for a run to the right or left, while the quarterback reads a defender to the backside. If that defender over pursues the zone handoff to the running back, the quarterback keeps the ball to the space that he vacated.

5 Eagles offensive linemen for 5 Giants defenders; the 6th defender (in the yellow box) becomes the option key.

In short, in the zone read, the quarterback and running back are going in opposite directions from one another.

The quarterback and running back aim in opposite directions

The zone read – for whatever reason – became known as the “read option.” This was a fine development, until it began to be applied to every option play from the shotgun or pistol formation.

The option key tackles the running back, so the quarterback keeps to the vacated space

The option key tackles the running back; the quarterback has correctly kept the ball.

Easy yards for the quarterback on the zone read (“read option”)

The most glaring example of this phenomenon was during the “read option” explosion in the NFL in 2012, when both the 49ers and Redskins had great success with the “read option” from the Pistol formation. The only problem is that the vast majority of their success was not from the “read option,” but from the veer scheme.

In the veer scheme, the option/dive key is the first man on or outside the offensive tackle

The key difference between the veer and the zone read is that in the veer scheme, the dive back and the quarterback are both attacking the same side of the field. In the traditional veer scheme, the offensive line does not block the first man on or outside the play side tackle. This becomes the option key. The dive back aims – at full speed – between the guard and the tackle. If the option key can’t make the tackle, the quarterback hands off, and the running back runs underneath the option key, following extra blocks on the second level and third level (because the tackle and tight end – if there is one – do not block anyone on the line of scrimmage, which frees them to block downfield). If the option key can tackle the dive back, he can’t tackle the quarterback. The quarterback keeps the ball, and follows the same extra downfield blocking (note that in a true veer triple option – which the 49ers and Redskins rarely ran – the quarterback would have a second option key and the option to pitch to a pitch back depending on that option key’s movements).

The quarterback and running back attack the same side of the field in the veer scheme. Here, the option key is too far up the field, so the ball is given to the dive back

Thus, in the “read option” the quarterback and the running back go in opposite directions, while in the veer scheme they attack the same side of the field and follow the same blocking.

The offensive line walls off the middle of the field, and the dive back follows behind, while the option key cannot recover

The dive back glides along the veer wall to the end zone

Less common in the NFL, but still mislabeled, is the midline option. The play is similar to the veer scheme, except that the option key is the first man on or outside the play side guard, and the dive back’s path is over center or just to the play side (depending on the coach). Again, this varies from the “read option” in that the dive back and the quarterback both run to the same side of the field.

The dangers of an overcomplex defense

Aggressive defenses with multiple fronts and complex blitz schemes create problems for offenses due to their multiplicity and unpredictability. These defenses are high risk, high reward, and high difficulty. They require skillful play calling, as “choosing wrong” in terms of pressure leaves the defense susceptible to huge plays. Sound, simple defenses – while lacking the same attacking and confusion creating abilities – are not as susceptible to such breakdowns. In other words, aggressive defenses are “boom or bust,” and too much complication can lead to breakdowns at inopportune times.

Such was the case during the 2012 divisional playoff game between the San Francisco 49ers and the New Orleans Saints. With 2:18 left in the game, the 49ers trailed 23-24, facing a 3rd and 7 at the 27 yard line. They came to the line with Frank Gore as the lone back, and immediately shifted to an empty formation, with a tight end and two receivers to the right, and two receivers to the left.

The Saints were an aggressive, blitzing team under coordinator Gregg Williams. This style helped lead them to a Super Bowl title in 2009, a year in which they were second in the league with 35 defensive takeaways. 2009 showed the “boom” of the defense, while the Saints were about to experience the “bust” in San Francisco.

Above, note the Saints alignment. It is clear that they have called a blitz in an obvious passing situation in order to put pressure on Smith. It is no mystery where the blitz is coming from. There are FIVE defenders near the line of scrimmage between right tackle Anthony Davis and Frank Gore in the slot. While it isn’t clear which of the five will rush the passer – such is the benefit of the aggressive defense – almost half of the defense is concentrated near the line of scrimmage in an area covering not more than ten yards. Not surprisingly, this leaves other areas of the field open to exploit.
We also see wide receiver Kyle Williams in motion. Cornerback Patrick Robinson follows him to the inside. Herein lies the most interesting aspect of the play. As the play unfolds, Robinson continues running towards the center of the field – even as the ball is being run in the opposite direction. He will run himself to the opposite hash as Alex Smith runs down the sideline for a touchdown. Nothing better illustrates the problem with an overcomplicated defense. Because it requires players to execute so many different schemes and coverages over the course of the game, they must devote brain power to performing many different assignments throughout the game. This means that they often cannot play without thinking, which causes them to lose sight of what is important – the ball. Such is the case here, as Robinson runs in a direct path away from the ball.

There is no misdirection as the play unfolds, above. Kyle Williams cracks the defensive end – a staple play from Pop Warner on up. Left tackle Joe Staley pulls to lead the play. Notice the five defenders to the right of the formation that we noted before the snap. They are wasted from the snap of the ball, with no chance to make a play. Cornerback Robinson is well on his way to the opposite hash. A simple quarterback sweep, and eight Saints are on the wrong side of the field. Of the remaining three, two are on the hash being cracked to the inside, and the third is Robinson sprinting in the wrong direction. The 49ers have almost half the field at their disposal, with Joe Staley leading the play and no one in sight for him to block.

Above, we see Robinson on the hash, and the remainder of the Saints in pursuit.

Joe Staley’s cut block seals the play.

Defensive coordinators must balance the benefits of aggressiveness and unpredictability with the necessity for execution. Many multiple, attacking defenses have been successful and will continue to find success, but coaches must ensure that the players are not so assignment driven that they lose sight of what is most important: stopping the ball. As the Saints showed against the 49ers, this issue exists even at the highest level of play. While it is easy to blame a player for an assignment mistake, a coach must also look to himself, and ask whether he has added more than his players can handle. Even if a player botches a seemingly “basic” defensive (i.e. a safety not covering his deep half of the field in cover 2), the coordinator must ask if this is a manifestation of the player’s inability to play without thinking as a result of overcomplexity. The danger of overcomplexity isn’t only seen in major plays of the game; often, it is in the moments of tentativeness that add up throughout the course of a game to act as an invisible sabotage to playing aggressive, winning defense.

Controlling the defensive line with the wham block

The wham block is an underutilized weapon that will turn the aggressiveness of a dominant defensive lineman against him.

Related to the trap, the wham block sends a skill player to block a defensive lineman from an angle with an element of surprise. Often utilizing motion, the wham discourages penetration by sending the message that the defensive lineman can never know when he will be blindsided along the line of scrimmage.

Diagram 1 (above) shows the blocking scheme for the play. Delanie Walker is sent in short motion, giving him increased momentum to blast Ndamukong Suh. Notice how the scheme, combined with trap and fold blocks across the line, allows 49ers offensive linemen to block down the field. This downfield blocking is a hallmark of big plays in the run game. The scheme turns the Lions aggressiveness against itself, wasting the defensive linemen who were quick to penetrate up the field.

Diagram 2 (above): The moment of impact.

Diagram 3 (above): The meeting of scheme and execution. The 49ers scheme has worked to perfection – two defensive linemen (including Suh, the disruptive force who necessitates the scheme) are already behind the play, wasted to the defensive. Four 49er offensive linemen are down the field to make blocks.

Also note Vernon Davis. As the play unfolds, he blocks his man across the field. In diagram 1, we see the defensive end lined up on Davis’s inside shade. In diagram 2, Davis has locked him to the inside. In diagram 3, Davis has begun to drive him across the formation. In diagram 4, Davis has driven him off the screen.

Davis’s block as well as the 49ers offensive line’s ability to block downfield reminds us that no matter what the scheme, the most important predictor of success is the execution of fundamentals.

Discouraging aggressiveness encourages passivity, which helps to control a dominant defensive line or a particular defensive lineman. The wham – despite having faded in popularity – is a valuable tool in achieving that end. It is one of the power elements that Jim Harbaugh has brought to the table in turning also-rans at the University of San Diego, Stanford, and the 49ers into contenders.
