Can anyone recommend football strategy/technique literature??

[c_nice_37]

After reading the Patriots playbook that was linked here a long time ago, my hunger for football knowledge in terms of actual X's & O's grew. Also adding to that fire was the recent post by Brady-to-Branch on the KC Joyner article.

Can anyone recommend any good books out there that get into the real technical details of football strategy / techniques / formations / etc?

F.O. also posts some pretty good articles on coverages last year, as well as the 4-3 and 3-4 gap structures, but they were too short.

Thanks.
