re: Interesting stuff here: Saban's 2001 Defensive Playbook

Here's where it and most of the other playbooks for both sides of the ball are stored.

The Playbook Exchange is a site high school coaches use, at least in Texas thy do.

Put your cursor on "Offense" or "Defense" along the red header towards the top of the page. You can pull of variants of nearly every offensive or defensive set known to man. Many were contributed and others, like Saban's, were probably smuggled out by an assistant or some fringe character.

Don't spend too much time viewing these at work and get fired. I nearly did once.
