In our Physical Education Student Leadership (PESL) class our teacher has been reading the book 'Legacy, What the All blacks can teach us about the business of life' by James Kerr to us as information to bring into our school work and our coaching sessions. In the book 'Legacy' the author James Kerr goes into great depth about the legendary sporting team The All Blacks and 15 of their effective lessons for leadership. The book talks about how the all blacks discipline themselves, how they present themselves to the public, support the public and communicate with the public and themselves etc. But as you can see its mostly about their image and discipline. The book also talks a lot about the business behind the all blacks.
Here is a link to buy the book and an image to potentially widen your knowledge about the all black and just show you a different perspective to the All Blacks:
