What is Cover 4 (Quarters) Rate?

Cover 4 rate is the percentage of a defense's coverage snaps played in quarters, with four defenders splitting the deep field evenly. It is the most conservative common shell against explosive plays, and defenses that live in it typically concede short completions and rushing yardage in exchange for keeping everything in front of them.
