Cover 4 (quarters)
What it is
Four defenders split the deep field into quarters, most often with match rules rather than pure zone.
Why it matters
Quarters looks like a soft two-high shell and plays like an eight-man front, because the safeties are reading number two and will come down on any route that is not vertical. That is what makes it the standard answer to run-heavy spread offences: it caps the deep ball and still gets a safety into the fit. It asks the most of safety recognition of any common call — a safety who reads the route late is either late in the fit or late over the top.
Also called
Programs call this quarters, cover four, four across or 2-read. The Coach answers to any of them.
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.
