I recently ordered about 10 defensive football books from Amazon.com, and one of my favorite football books of all time is becoming Football Winning Defense, 1994 Sports Illustrated published book by Bud Wilkinson, a member of Football's Hall of Fame. Coach Wilkinson coached the University of Oklahoma to 47 straight wins, an all time record.
The book is very well written and simple to understand. Coach Wilkinson's no nonsense way of writing is what makes me love this book. I must have highlighted 50% of this book.
I love this quote, "If your opponent does not score, you cannot lose. The worst you can do is tie"
