Double CB Blitz is an aggressive man-pressure package out of the Over Wide 2-4-5 Big Nickel look that sends both cornerbacks off the edges as extra rushers while the defense plays man coverage behind it. The linebackers and safeties lock onto their assignments while the corners create a numbers advantage against the tackles or tight end blockers, aiming to collapse the pocket before the quarterback can hit his second read. This is a blitz-heavy man beater designed to disrupt timing throws, and the primary read progression is diagnosing whether the offensive line picks up the extra rushers pre-snap, then keying the running back or tight end for any hot route breaking into the vacated flat or curl area during the blitz.
Read the running back's alignment pre-snap, if he is set to the same side as your blitzing corner he can often chip or fully block the rusher, so consider blitzing the corner away from the back. Watch for quick game concepts like slants and hitches, since man coverage behind the blitz is vulnerable to fast timing throws that beat the rush before it develops. Identify play-action or RPO tendencies from the offense, if they run heavy zone read or RPO concepts this blitz can be gashed on the ground since the second level is thinned out by the corner blitz. Look for stack or bunch formations before the snap, natural picks and rubs against man coverage will nullify the blitz advantage and open easy completions underneath. Post-snap, track the tight end or slot receiver on any seam or option route, since the underneath defenders are locked in man and a free release vertical threat can expose the coverage while the corners are committed upfield.
Only call this on early downs or third and long when the offense is likely to sit in a five or seven man protection, since running it into empty formations leaves your corners exposed on long developing scrambles.
Check the offensive personnel pre-snap for six man protection or extra blockers, if you see two backs or a heavy tight end set, this play loses value fast because both blitzing corners can get picked up easily.
User the field side blitzing corner and time the snap count so you cross the tackle's face before he sets his feet, this is the difference between a free rusher and a blocked dead rep.
Pair this with Cover 1 Sting Wk or Cover 3 Sim Pressure earlier in the series so the offense sees consistent pre-snap shells and cannot key the double corner blitz look before the snap.
Avoid calling this against trips or bunch formations to the blitz side, since natural rub routes and free releases will beat the man coverage behind the pressure before it ever arrives.
