You see it every Sunday, but just how to NFL defensive backs handle switching? We break down Gregg Williams’s New York Jets defense.
You, that diehard NFL fan, witness it every Sunday. You may not exactly know what you’re witnessing, but it’s there.

Saban, the then-Cleveland Browns defensive coordinator, had a problem that needed wrestling in the early 1990s. His defense required an extra guy in the box yet he knew his guys weren’t good enough to cover man-to-man (Cover 1). On top of that, when he went Cover 3, four verts would burn him.
Playing three deep against four verts just does not make much sense, so Saban went to work on what would become pattern-match zone. Instead of thinking zone defense as a strict, drop or run to an area-type coverage, reads and responsibilities would creep into every cover man’s thought process.
This way, if four verts happened against a Cover 3, every route would be covered.
