I agree with this: that's a blitz that really can only be run against 3X1. And even then, you would need to have the backside corner locked up in man coverage. The backer playing Seam/Curl/Flat (SCIF) would then relate to the first crosser or to the back if he releases weak. But since the offense is usually going to slide weak in turn protection (half-slide), the back will probably go to the other side (since the back and center almost never go to the same side in Pass Pro unless the QB makes a TOM [
Tailback
On
Mike] call).
It also illustrates my earlier points about how blitzes need to be adaptable based on offensive formations: certain stock pressures can't be run against certain formations and still be "sound." Different guys will pressure based on the offensive set. For example, against 2X2 with two detached slot receivers, a 3-4 team playing Quarters really can't pressure an OLB in the Base defense because they need them both to walk out and at least apex (split the difference) between the receivers and offensive tackles to their respective sides. If the formation were 2X2 with a TE in the box, though, you can pressure with the SOLB.
Little details like the above is the difference between playing successful team defense: if you're unsound in alignment you're beaten from the start.
Back on topic: I would set up the show blitz mechanic so that guys would start milling around like the Steelers do in their "Chaos" package. Once you hit the button, you're stuck with it: you can't change back unless you audible the entire defense (to prevent the shake blitz).
I also want an option to pick what kind of pre-snap shell I want on defense: I don't necessarily always want to start my alignment in 2 High every snap and roll late. However, either way I want my backers to pre-align where they need to be: i.e, If I'm in an Under front and I have my safety rolling weak the WILL and MIKE better ****ing BOSS (Bump Out Strong).
Good post.
