Quarters coverage in football is fast becoming the most popular defensive coverage. The major reason for the rise in popularity is that it allows the defense to get both safeties involved in stopping the run while also remaining sound against the Four Verticals passing concept. Like any coverage, the secret to running Quarters well is creating clear rules for the secondary.

The most difficult position to play in Quarters Coverage is safety. Safetys have the responsibility of covering any vertical route by number 2 and stopping any run to the D gap on their side.
