The next few posts will explore some basic concepts of their passing attack to horizontally and vertically stretch defenses and provide easy answers to any situation. I don't intend to reinvent the wheel here - most of these concepts have been covered extensively before, either on smartfootball (which we'll borrow heavily from) or this site. We're merely attempting to provide an overview of the concepts (this site is mainly for coaches who already know this stuff) and how they adapt to a defense's response. These methods are actually quite common and are the standard blueprint for the modern offense ( air raid principles ). What makes the application for the Saints so effective obviously is a more-than-competent quarterback, a bevy of consistent receiving threats, and an emphasis on the 3-step game to alleviate pressure on the offensive line to be engaged in pass protection for extended durations.
smartfootball, the 4 vertical package is a 5-step concept that is best run out of 1-back or no-back sets meant to horizontally stretch deep safeties.
The illustration shows the 4 vertical package, and subsequent pictorials will be overlaid with the 4 vert concept to demonstrate how the stems will appear the same.
As you will see in the clips below, it can be run out of any formation and even out of play-action ( becomes "Rodeo / Lasso" in 'the system ).
Variations of the 'dig' concept
shallow /levels /drive), the concept is made more effective by running a player into the intermediate hole of a defense while simultaneously running another player at a lower depth to create two (often intersecting) levels on underneath inside defenders.
