Pattern match
What it is
Zone rules that convert to man once the route distribution declares, so the defense keeps zone eyes and man leverage.
Why it matters
The defender starts on a zone landmark and reads the receivers in his area; when the pattern declares he matches the one who fits his rule and carries him like man. It answers the classic zone weakness — a receiver sitting in the seam between two defenders — without giving up the ball-hawking eyes that make zone worth playing. It asks far more of communication, because two defenders reading the same distribution differently is an uncovered receiver.

See it on the field
A two-high shell that plays like an eight-man front once the safeties read number two. The alignment comes from the engine’s own front resolver against real offensive splits, so it is a picture the simulator genuinely produces — not a diagram drawn to make a point.
