Here's the first sack of the game, by Tartt - it's a well designed, and even better executed blitz. It's nothing super exotic, just really well executed out of a different pre-snap look.
What we do is move Reid down on the LOS and show 7 at the LOS, with 5 standing up. It's not a super exotic blitz, we're just going to come through one "A" gap and off the edge and play a "fire" zone behind it. "fire" zone is a 3 deep, 3 underneath zone that looks to take away the middle and quick hook areas - to beat a quick seam throw. We only rush 5.
Both Bowman and Brooks drop back in coverage, this helps cover up and "hot" routes and takes away any quick, pressure beaters the Vikings may employ.
You see at the sack, there was nobody open. Bridgewater would've needed an extra second for his deep out to become open, even then, would take a clean pocket to make that throw.
Here's how our front looked. It's very intimidating to an offense and very difficult for them to have 100% sure who's got who. The key on this play are the rushes of the DT's. They rush to the outside shoulders of those guards, no wider, no more inside. This forces the guards to take a step out and creates a lot of space on the center, who has 2 men over him. He expects help one way, and gets none because of a blitzing Reid.
The center had planned on blocking Bowman, so he steps to his right(our left) which, combined with Tank's wider rush, opens up a huge lane for Tartt to run through - a true, "parting of the red sea". Reid's blitz also catches the attention of Peterson who slides out to block Reid, so no one is left to pick up Tartt.
By the time the center realizes what's happened, it's too late - that's a sight defenders dream about.
From the offense's view, you can see how it'd be so hard to tell who's coming and who's not. You see Peterson started inside(where the center was expecting help).
Then Peterson goes to take Reid, leaving Bridgewater SOL.
You see what Bridgewater saw, no where to throw the ball and a full speed defender coming at him. That's what precise execution of a blitz can do - if the tackles don't execute this right, the offensive line can bunch this up. This is a great way of being able to only bring 1 extra pass rusher and get immediate pressure.
