Breakdown

Fz 3 Sky is a zone blitz out of the Quarter 1-3-7 set that sends pressure while dropping into a Cover 3 Sky shell behind it. The diagram shows two deep outside defenders pushing vertical to the numbers with a deep middle defender bracketing the post area, while the two purple underneath zones sit at the flats and hook areas to rob quick throws. Up front, four rushers attack downhill with one edge defender bending the arc, indicating a five man pressure look with a Sky safety rotating down to fill the run support or curl to flat responsibility. This is a zone beater blitz designed to disguise pressure while still playing sound zone drops behind it, and the primary read progression for the defense is to first identify the quarterback's eyes toward any hot route or slot release, then trigger on the underneath purple zone defenders to squeeze the flat and curl throws before the deep thirds close off any shot plays.

Defensive Reads

Key the offensive line splits and running back alignment pre-snap, since a heavy protection call often signals the quarterback expects pressure and will look to get the ball out fast. Watch for the slot or tight end releasing into the flat immediately after the snap, since that is the first area the underneath purple zones must close down against quick game. This call is strong against man beater concepts and rub routes since the zone drops naturally clog crossing routes, but it can be exposed by well timed rollouts or play-action rollouts that get outside the rush lane. Post-snap, track the deep middle defender's positioning against any vertical seam or post route, since that defender is the last line against a big shot play if the pressure does not get home in time. Look for the quarterback checking the ball down to the running back quickly, which usually means he identified the blitz pre-snap and is trying to beat it with a quick outlet before your underneath defenders can rally.

Usage Tips

Call Fz 3 Sky on early downs or third and medium when you expect the offense to try quick game or spacing concepts against your zone blitz look.

Use the pre-snap picture to bait the quarterback into thinking it is a standard Cover 3 shell, then let the disguised pressure get home before he can climb the pocket.

Hot route the underneath purple zone defenders to squeeze shallow crossers if you are facing a lot of drag or spacing concepts, since the natural landmarks can be a step slow against fast motion offenses.

Pair this call with Cover 3 Mable or 3 Double Mable in the same set to keep the same Cover 3 shell picture while alternating between blitz and standard drop coverage, making it harder for the offense to key on pressure.

Avoid calling this on clear passing downs against empty formations, since the five man rush can be picked up easily and leave the shallow crossers open before your zone defenders can rotate over.
