What is Cover 9 Rate?

Cover 9 rate is the percentage of a defense's coverage snaps played in a three-deep match structure, where defenders pattern-match receivers into their zones rather than dropping to fixed landmarks. It is a rarely charted shell, so single-season sample sizes are small and week-to-week swings should be read with caution.
