Edge Blitz 0 out of Nickel Over sends both edge defenders (the outside X icons) crashing off the corners while the interior four (squares) all converge straight downhill through the A and B gaps, creating a true zero blitz with no deep safety help behind it. The two outside circles show man coverage assignments on the perimeter, confirming this is a Cover 0 blitz with every underneath defender locked in man across the board. Because it is a pure pressure call with no free safety over the top, the design lives and dies on beating the offensive line to the quarterback before any man coverage bust or hot route can be exploited deep.
Pre-snap, confirm both safeties are creeping toward the box or shading over the slot since zero blitz alignment usually removes the deep middle defender entirely. Watch the running back and slot receiver alignment because their release will tell you whether the quick hot route or the check down beats your rushers before they arrive. Post-snap, key the offensive line's slide protection direction and get your unblocked rusher to the opposite edge since that is the free run lane this play is designed to create. This look gets exposed by quick game concepts, hitches, and slants that convert into man beaters against tight coverage, so if the receivers are stacked or bunched expect a rub route designed to shake the corner. Avoid calling this against empty backfield sets or spread formations with four or five wide since the extra eligible receivers make it harder to disguise where the free rusher will come from.
Call this on third and long or in two minute situations when the offense is likely to hold blockers in for protection and you need a home run pressure look. Check the offensive personnel pre-snap and if they show six or seven protectors, consider audibling out since Cover 0 with extra rushers gets home fast and does not need the numbers advantage. Manually spy or user the most athletic edge rusher to contain scrambling quarterbacks since zero blitz has no safety net if the pocket gets extended. Disguise this by showing Cover 1 Robber Press or Cover 1 SS Blitz pre-snap from the same set so the quarterback cannot key the blitz from alignment alone. Pair it in a sequence with Cover 1 LB Blitz and FS Will Blitz 0 to keep offenses guessing between one high shells and true zero pressure out of the same Nickel Over look.
