Mlb Cross Fire 3 is a Cover 3 blitz out of the 3-4 Under, Base 5-2 personnel. The diagram shows a middle linebacker blitz crossing with an interior lineman stunt (the X pattern under the box), while the two outside linebackers and the SS drop into their Cover 3 zone assignments (deep thirds and underneath flat/hook zones). The three deep defenders (blue ovals) rotate to a three deep shell while the underneath defenders (purple and olive ovals) hold flat and curl/hook zones behind the cross fire stunt. This is a zone beater against the run and a pressure package versus the pass, with the primary read being the interior line stunt getting quick pressure up the middle before the QB can find a crosser or checkdown against the Cover 3 shell.
Pre-snap, look at the offensive line splits and RB alignment, since tight splits and a pass blocking back usually mean they expect interior pressure and will try to slide protect into the stunt. Watch the slot and inline tight end releases, because quick option or hitch routes are the first answer to this blitz and the underneath zone defenders need to squeeze those windows immediately. Post-snap, key the center and guard reactions to the stunt, if they pick it up cleanly the quarterback will have extra time to work a deep crosser against your Cover 3 rotation. This call beats teams that rely on inside zone runs and quick game passing concepts, since the interior stunt disrupts blocking angles and rushing lanes before they develop. This call struggles against max protect play-action or five step drops with vertical routes stacked on the weak side, since the underneath defenders are occupied with the stunt and zone drops.
Use this on early downs or short yardage third downs when you expect a run or a quick pass, since the Cross Fire stunt is designed to blow up interior gaps immediately.
Check pre-snap for a lone deep safety or an empty backfield, both of which tip that the offense is loading up on quick game or screens that can hurt a green dog blitz.
User the Mlb after the snap and manually time the stunt through the A or B gap to disguise the exact rush lane, since the CPU stunt alone can be too slow against instant hot route throws.
Pair this call with Cover 3 Sky or Cover 3 Hard Flat on the following snap so the offense sees the same shell but does not get the interior pressure look, keeping quarterbacks guessing between coverage only and blitz.
Avoid calling this against empty formations with a hot back released quickly, since the underneath zone defenders can be isolated in space if the stunt does not get home fast enough.
