Strg Corner 2 Fire is a Cover 2 zone blitz out of the Dime 2-3-6 Will set that brings a corner blitz off the edge while dropping the rest of the defense into a five-man zone shell. The diagram shows two deep safeties splitting the field in half turns, four underneath defenders sinking into shallow zone drops, and the strong side corner firing downhill off the edge as the fifth rusher. This is a zone blitz designed to disguise pressure while still protecting the deep middle and sidelines with the two-deep shell, making it a strong zone beater against quick game and a trap against quarterbacks who hold the ball expecting standard Cover 2 spacing.
Pre-snap, check if the offense is in a formation that overloads the blitzing corner's side, since a bunch or stack set can create natural rubs that free up receivers before the corner even gets home. Watch the quarterback's eyes immediately after the snap. If he looks quickly to the blitz side flat, be ready to user the underneath defender there since that space is thinned out by the corner vacating. Key the two deep safeties to ensure they stay disciplined on go routes and deep posts, since blown coverage on top usually results from a safety cheating down too early to help against the run. This call is most effective against play designs that rely on a five to seven step drop, since the extra rusher usually reaches the quarterback before deeper routes fully develop. This call is vulnerable to hot route adjustments that convert routes into quick hitters or screens to the blitz side, so recognize screen action immediately and get depth-conscious linebackers to break down in space rather than pursuing upfield.
Call this on early downs or third and medium when you expect the offense to run quick game or shallow crossers against what looks like a standard two deep shell.
Disguise the corner blitz by showing normal Cover 2 depth pre-snap, then bring the corner late so the quarterback commits to his first read before recognizing the extra rusher.
Use the flat zone defenders to squeeze underneath option routes and stick routes, since the diagram shows tight underneath drops that clog passing lanes near the line of scrimmage.
Pair this with Cover 2 Sink or Cover 2 Hard Flat in your play-calling sequence so the offense sees a similar shell but cannot key on the same blitz look every snap.
Avoid calling this against empty formations or heavy trips sets since the vacated corner spot on the blitz side can be exploited by a fast receiver running a quick out or speed out into that space.
