Best OL book I have seen
The book is very informative to coaches of all levels. Even better was his presentation at a recent Coaches Clinic I attended. If you had any questions from his book he was more than happy to explain, even demonstrate, what he meant. Excellent content from an exellent coach.
A clear and concise framework of essential skills.
Coach Christensen provides a clear and informative book on developing essential skills in offensive lineman. I believe this book is a "must have" for any line coach or head coach at any level. Each type of block, accompanying points of attack etc. is clearly described with excellent diagrams. Overall, an outstanding book.
