FIG. 1Sim Pressure: pre-snap alignment and each rusher's path. The numbers match the roles list.

Simulated pressure (Sim Pressure) is the art of showing a blitz from one side while actually rushing from the other. The JACK outside linebacker creeps up to the line showing rush, then drops into coverage at the snap while the weak-side DE peels into the flat behind him. The real pressure comes from the opposite side: the WILL crosses the formation into the strong A-gap, the strong-side DE crashes inside to the B-gap, and the SAM rushes the edge. The offense must honor five potential rushers across the line, but only four come — the nose, the SAM, the crashing DE, and the WILL — all loaded away from the show. The QB's pre-snap protection call slides toward the JACK and blocks ghosts.

Roles

Numbers match the keys on the field. Tap a player for his role in the stunt.

Strengths4

  • Strength: Forces the QB to make the wrong protection call by showing pressure from the wrong side
  • Strength: Only rushes four, maintaining a full coverage shell behind the pressure
  • Strength: The JACK's show-then-drop action freezes the offensive line, creating hesitation
  • Strength: Extremely effective on early downs when the offense does not expect pressure

Weaknesses4

  • Weakness: Requires the JACK to be a convincing actor, a half-hearted show is easily read
  • Weakness: The WILL must time his blitz precisely or the interior OL will pick him up
  • Weakness: If the QB recognizes the sim pre-snap, he can audible to attack the dropping JACK's zone
  • Weakness: Vulnerable to no-huddle tempo that prevents the defense from setting up the disguise

How the offense counters

4
  • No-huddle tempo to prevent the defense from setting up the disguise
  • Identifying the JACK's pre-snap alignment as a tell (too far off the ball to rush)
  • Quick passing concepts that negate any pressure regardless of direction
  • RB check-release that scans both sides before committing to a route

History

Simulated pressure became the defining schematic trend of the 2010s NFL. Vic Fangio pioneered the modern approach in Chicago and Denver, and his protege Brandon Staley carried it forward in Los Angeles. Brian Flores, from the Belichick coaching tree, independently developed aggressive sim-pressure packages in Miami. The principle is simple but profound: you do not need to bring extra rushers to create pressure; you just need to make the offense think you are bringing them from a different direction. Modern analytics show that sim pressures generate nearly the same pressure rate as true blitzes while giving up significantly fewer explosive plays.
