Steve Wilks’ defense is likely to rely heavily on a pattern-matching style of Cover 3 zone. But no defense can stay in the same playcall on every play and expect to be successful. Cover 3 allows the defense to play in a safe coverage, while relying on talent in the front 4 to apply pressure to the quarterback.
When the defense needs to turn up the heat against the pass or needs a convenient run blitz, a Zone Blitz is an efficient an effective choice. One of the strengths of zone blitzes is that they are safer than blitzes that are employed in combination with man to man coverage.
