Dbl Safety Blitz brings both safeties downhill from depth on a Dime 4-1-6 blitz package, with the two safeties and the middle linebacker all crashing hard toward the line while the four defensive linemen occupy the box up front. The corners are left in off-man or press alignment on the outside receivers with no deep safety help over the top, making this a max pressure call designed to force a quick throw or sack. Primary read is the quarterback's eyes at the top of his drop: get immediate pressure up the middle and force him to speed up his internal clock before he can find a hole in the underneath coverage.
Watch the running back and tight end release patterns immediately after the snap, since any check release into a flat route is the first outlet against this pressure and the user defender needs to jump it fast. This call is most effective against slower developing man beater concepts and drag routes that need time to clear the underneath zones, since the double safety pressure collapses the pocket before those routes can fully develop. It gets exploited by hot route sight adjustments and quick game concepts like slants and stick routes, so if the offense audibles to a three step drop before the snap consider backing out of this blitz. Pre-snap, check corner depth and leverage on the outside receivers, since press coverage with no safety help is a green light for the offense to take a shot on a go route or fade if they diagnose the blitz. Post-snap, key the offensive line's protection slide, if they slide toward one blitzing safety the opposite safety usually comes free for a home run hit on the quarterback.
Use this on third and long or in short yardage passing situations when you expect the offense to sit in the pocket and read the field, since the double safety pressure eliminates their time to scan through multiple progressions.
Pre-snap, check the offensive formation for empty backfield or trips looks that could expose your blitzing safeties to a free runner picking up the extra rusher, and be ready to check to a coverage play like Cover 4 Quarters if you see four verticals stacked against you.
User the middle linebacker or one of the blitzing safeties to disguise which gap you are attacking, then release your user control just before the snap to bait the quarterback into a bad presnap read.
Pair this call with Cover 1 Contain or Cover 2 Man from the same set on early downs so the offense cannot key blitz tells purely off safety depth in your presnap alignment.
Avoid calling this against empty formations with a mobile quarterback who can escape the interior pressure lanes, since the corners have zero safety help deep once the ball is out.
