FS Will Blitz 0 is a Cover 0 zero blitz out of the Nickel 2-4-5 personnel that brings the free safety and Will linebacker off the edge to overload the protection while every remaining defender locks into man coverage with no deep help. The diagram shows five underneath defenders converging downhill from a tight pre-snap alignment, with two corners pressed outside on the numbers and no single high safety left over the top. This is a pure pressure package designed to force a hot throw or collapse the pocket before the quarterback can climb, so the primary read progression for the offense facing this is getting the ball out immediately to the first uncovered receiver or check down.
Pre-snap, check the offensive formation for max protect looks like two backs or extra tight ends, since that tells you the blitz will likely be picked up and you may want to audible. Watch for the quarterback sliding the protection toward the blitz side, which signals he has identified the zero pressure and may be hot routing his hot receiver to the opposite side. This play crushes empty backfield sets and slow developing play action because there is no time for routes to break open against immediate pressure. It gets exposed by quick game man beaters like slants, speed outs, and hitches since your corners have no safety help and must win their one on one matchup instantly. Post-snap, key the running back's release, if he stays in to chip or block, count your rushers again to confirm you still generate a free hitter off the edge.
Call this on third and long or in obvious passing situations where the offense is likely to run a slower developing route combo that your extra rushers can beat before it develops.
Before the snap, identify if the offense has a running back or tight end staying in to block, since that changes your blitz math and you may need to spy or adjust who comes free.
Use your user-controlled defender on the most athletic offensive weapon rather than blitzing with him, so you can bail into a robber or lurk technique if you smell a quick game beater like a slant or stick route.
Mix this in after showing Cover 1 LB Blitz or Cover 1 Robber from the same set so the quarterback cannot key off safety depth pre-snap and diagnose the zero look.
Avoid calling this against empty or trips formations without adjusting your assignments, since the extra blitzer can leave a receiver wide open on an island with no safety help over the top.
