Rugby: The Art of Scrummaging: A History, a Manual and a Law Dissertation on the Rugby Scrum (Paperback)
"RugbyThe Art of Scrummaging" contains many ideas and recommendations for coaches that will allow them to produce players who understand the necessary skills, thereby increasing their enjoyment through higher efficiency. That higher efficiency will also make their involvement in the scrum much safer, something that has been at the center of this project's focus.
For coaches to teach well they have to be properly taught themselves, and the advice of all the scrummaging luminaries associated with this work will help them.
"RugbyThe Art of Scrummaging" also presents many ideas on what might lead to better and safer scrum laws and better officiating. It does not include definitive recommendations on these two subjects, but provides a bank of information that should assist in any future reviews.
