Double CB Blitz is a max pressure package out of the 3-3-5 Over Wide set that sends both cornerbacks off the edges in addition to the standard front seven pressure, creating a five or six man rush look designed to collapse the pocket before the quarterback can climb. This is not a coverage-based dropback call, it is an all out blitz built to force a fast throw or a sack, leaving the defense in some form of man coverage behind the rush with minimal deep help. Your primary read as the defender is not a route progression but a pressure trigger: watch for the offensive tackle or tight end sliding out to pick up the blitzing corner, and if both corners get through clean you are playing for a strip sack or a forced incompletion rather than a covered route.
Pre-snap, check where the running back and tight ends are aligned since they are the first blockers who can pick up a blitzing corner and neutralize the pressure. Identify if the offense is in shotgun with a running back on both sides, which signals they may have hot route protection already built in against corner pressure. Post-snap, key the tackles and guards immediately to see if anyone is sliding outside to help versus the corner rushers, and if the offensive line stays home your pressure will win clean. This play crushes empty or trips formations that leave receivers without inside help against the blitzing corners, and it is especially effective against teams that love to sit in the pocket and go through a long progression. This play gets shut down by max protect schemes with seven or eight blockers and by hot route beaters like quick slants and screens that punish the vacated corner spots, so if you see six or seven potential blockers pre-snap consider backing out of the blitz.
Save Double CB Blitz for third and long or two minute drill situations where the offense is likely to hold the ball for a deep shot, since the corner blitz needs extra time to develop and gets exposed against quick game.
Check the offensive formation before the snap. If the offense has trips or bunch to one side, the blitzing corner on that side may get picked off by a natural release, so consider flipping the play or manually spying that corner with the R stick.
Combine this with Cover 3 Sim Pressure or Fire Man earlier in a series so the offense sees pressure from the front seven first, then dial up Double CB Blitz to catch them off guard when they expect standard four man rush disguises.
User the strong side corner blitzer if you are comfortable timing the snap count, since a well timed user rush from the corner spot is nearly unblockable against tackles who are not sliding to that side.
Avoid calling this against empty backfield sets or heavy shotgun spread looks where the quarterback has a built in answer to blitz with quick outs and slants, since your corners are out of position to help underneath.
