Book recommendations - 40 Front

I've read a TON of defensive books and there is no better 40 defense resource than "Coaching the 40 Nickel Defense".....practical and easy to read great for every phase of the defense.

If you are new to defensive concepts, though, read Fritz Shurmur's "Coaching Team Defense" to set your understanding of fundamental defensive concepts - I found out the hard way that there are coaches (on my former staff) that were not grounded in some ideas on defense.

Notebook on EBAY now called "THE AUBURN 4-3 DEFENSE". Also a University of Miami defensive notebook. Look under FOOTBALL PLAYBOOK.
