SS Blitz 0 out of the Nickel 3-3 Cub set brings the strong safety off the edge as a fifth rusher while the defense plays Cover 0 man behind it, leaving zero deep safety help over the top. The diagram shows all five underneath defenders firing downhill with hard vertical arrows, four straight blitz lanes and one defender angling inside, while the two cornerbacks and remaining safety lock up receivers man to man with no zone drops shown. This is a true zero blitz built to win with pressure, so the primary read is get to the quarterback before the man coverage breaks down, since there is no deep help if a receiver wins his release.
Pre-snap, check safety depth and cornerback alignment, if both safeties are tight to the box and corners are pressed at the line you have confirmed Cover 0 and the blitz is live. Post-snap, user the strong safety blitzer immediately and target the widest gap or the running back's protection assignment, since he is often the free rusher in this look. This beats offenses that keep only five or six in protection, quick game concepts, and slow developing play-action rollouts that need extra time to set up. This gets shredded by hot routes into quick slants, screens, and any route that beats man coverage in isolation, since there is no safety net over the top. Watch for a lurking linebacker sitting in the shallow zone (if your set has one), he can jump underneath routes if the quarterback tries to check it down against the blitz.
Call this on third and long or in two minute situations when the offense is likely to max protect or run five wide, since fewer blockers means your extra rusher wins faster.
Check the play art pre-snap for empty backfield or trips looks that signal quick game, then user the strong safety blitzer and aim him at the widest gap the offensive line leaves open.
Pair this with Cover 1 Robber from the same set as a disguise package, showing the same walked up safety look presnap then bailing into a zone drop on obvious pass downs to keep quarterbacks honest.
Motion the offense's running back or tight end before the snap to confirm man coverage, if defenders shift with the motion you know the Cover 0 shell is live and the blitz timing will be clean.
Avoid calling this against empty formations with a mobile quarterback unless you have a spy built in, since the lack of deep help punishes any free running lane for the passer.
