Cover 6 Willie is a split field zone coverage out of the Nickel Over set that combines quarters concepts to one side with a sky/cloud flat and deep half look to the other. The diagram shows two deep defenders sinking to the top of the screen on the strong side while a flat defender sits underneath at the numbers, and to the boundary side a corner drops into a deep third read with a curl/flat defender underneath, all while four down linemen rush and a hook defender spikes downhill to rob the middle. This is a zone beater killer for offenses since it is designed to defend both quarters and three-deep concepts simultaneously, with the primary post-snap read for the defense being the number two receiver to the strong side, since his release dictates whether the deep defenders roll to quarters or bail into a split safety shell.
Watch the strong side number two receiver at the snap, his vertical release triggers the quarters rotation while a shallow route lets the flat defender sit and jump underneath throws. This shell struggles against quick slants and stick concepts to the boundary side since the corner is dropping deep and the flat defender has to cover a wide zone, so expect user receivers to attack that void. Look for four verticals concepts to be neutralized here since both deep safeties and the corner rotate to the top of the screen, taking away the seams and the deep outside routes. Man beater route combos with heavy motion can cause confusion in the rotation, so pre-snap motion adjustments and matching leverage on the slot receivers is critical before the ball is snapped. If the offense runs a spot concept or smash combo to the single receiver side, the flat defender must sink fast and the deep defender needs to close on the corner route or this coverage gets picked apart in the flat to intermediate area.
Call this out of Nickel Over on early downs when you expect the offense to run four verticals or a mesh concept, since the split field shell defends both without needing a pre-snap adjustment.
Key the number two receiver to the strong side before the snap, if he releases vertically the deep defenders should stay high, if he runs a shallow crosser you can afford to squeeze the underneath hook defender.
Pair this play with Cover 4 Quarters and Cover 3 Cloud in your play-calling sequence so offenses cannot tell from formation alone whether they are getting a quarters shell or a three-deep shell.
User the hook defender that spikes downhill in the diagram to rob any middle read or shallow drag, since this is the area quarterbacks attack most against split field zones.
Use this on second and long or third and medium situations where you expect a mixed route concept attacking both hashes, since the split shell covers sideline to sideline without overcommitting resources.
