If your approach this book as a rugby book and therefore think it doesn't have valuable lessons for leadership and organisational development then you are going to literally judge the book by its cover and miss out on some goodness.
James Kerr has done an excellent job of capturing why the All Black's organisation is so successful. Essentially it is due to knowing what it is about, being focussed on learning and really deliberate about executing what it believes.
It is an easy read, easy to dip into and out of. Highly recommend.
