DB Blitz 2 is a five-man DB blitz out of the Quarter formation Over Load set, sending both outside cornerbacks off the edges while the interior defenders drop into a two deep, four under zone shell behind them. The two deep safeties sink into their Cover 2 halves, the linebacker and slot defenders wall off the shallow crossers and flat zones, and the underneath zone defenders squeeze the middle to take away quick hitters. This is a zone beater blitz designed to disguise pressure while still holding a two deep safety look, so the primary read is to bring immediate outside heat off both edges while trusting the shell to eliminate easy check downs underneath.
Pre-snap, confirm both cornerbacks are aligned wide enough to get a clean blitz angle off the edge without getting picked off by tight end or fullback chip blocks. Watch the offensive tackles and running backs for cues on whether they are sliding protection toward one side, which tells you which blitzing corner will win first. Post-snap, key the two deep safeties dropping into their Cover 2 halves and be ready to user one of them if the quarterback tries to attack the deep middle seam between the zones. This play is vulnerable to hot routes and quick screens to the flat since the blitzing corners vacate the perimeter, so if the offense checks into a bubble screen or quick out, rally your underneath zone defenders immediately. It shuts down teams that rely on max protect deep shots and slow developing play-action rollouts, but it can be exposed by quick game concepts and hitches thrown before the corner pressure arrives.
Call this on third and medium to third and long when you expect the offense to hold the ball for a deeper route concept, since the corner blitz off both edges gets home fast against slower pass protection. Check the pre-snap formation for tight bunch or stack sets that could pick off your blitzing corners with natural rub routes, and audible to Cover 0 Blitz instead if you see a heavy trips look that overloads one side. Use the flat zone defenders to bait quarterbacks into thinking there is a soft spot underneath, then user one of the deep safeties to jump any deep out or comeback route breaking toward the sideline. Mix this play into a sequence after showing Heavy 3 Zone or 3 Rat Zone earlier in the series so the quarterback sees the same pre-snap shell and cannot distinguish the blitz from the standard zone drop. Save this for money downs against offenses that rely on max protect play-action shots, since the two deep safeties can still bracket the deep half while the corner pressure disrupts the quarterback's launch point.
