Dbl Safety Blitz is a five-man pressure look out of the Nickel 4-2-5, 3-3 Over set that brings both safeties off the edges while showing a three-under drop shell underneath. The diagram shows the two outside defenders (the X's aligned wide) crashing downhill toward the box, the interior defenders spilling into short hook/curl drops, and two deep defenders (the dots) staying home to protect the middle of the field. This is a blitz play designed to disguise pressure while keeping a two-deep safety look post-snap, so the primary read is getting home fast off the edge before the quarterback can identify the hot route or check into a quick game beater.
Pre-snap, check safety depth and width: if both safeties are cheating up near the box before the snap, savvy opponents will suspect the blitz and audible to a screen or quick slant beater. Watch for the offense sliding protection toward the field or checking running backs to chip the edge, since that is the primary counter to double safety pressure off the corners. Post-snap, the underneath zone defenders should stay disciplined in their hook and curl drops to squeeze any quick game or stick concept thrown to beat the blitz. This look is vulnerable to hot routes and sight adjusts on slants or quick outs to the boundary, so if the corner is playing off coverage the receiver can settle in the void before the safety arrives. This pressure beats empty and shotgun spread formations that leave the edges thin, but struggles against max protection or two tight end sets that can pick up both blitzers cleanly.
Use this on third-and-medium or third-and-long when the offense is likely to take a five-step drop or shotgun action, since the double safety pressure needs time to develop.
Show a base Cover 2 Man or Cover 2 Roll shell before the snap and then bring the safeties late to disguise the blitz, since offenses that diagnose two-deep pre-snap will check into hot routes designed to attack vacated safety zones.
Pair this call with Cover 2 Invert or Cover 6 Willie earlier in a series so the offense sees the same shell and cannot key on safety depth or width as a pressure tell.
User the middle hook defender to rob any quick crosser or drag route since the three underneath zone drops leave a natural window in the intermediate middle if the edge pressure does not get home in time.
Avoid calling this against empty or trips formations that can identify and slide protection to the blitzing safeties, and instead save it for two-back or two-tight personnel where the safeties have a clean runway to the quarterback.
