Anyone have good custom playbooks for defenses?

[Punter715]

I'm setting up a league for me and some friends, and I'd like to have provided playbooks that match schemes. I've built a few offensive schemes - West Coast, Air Raid, Smash Mouth, Vertical Passing, Pro Style - but defense is harder to put together.

I would love to have the same ideas for defense, but it doesn't feel as fleshed out. For example, I'd love to have a 3-4 Zone Blitz scheme like the Steelers used to run under Lebeau, but I don't see any plays like that in the 3-4 playbook.
