There is a wealth of information on what leadership looks like. But I really believe this book hits upon an aspect of leadership that you might not have considered. Author Sam Walker devised stringent criteria for choosing 16 top performing sports teams and asked himself a very definite question - 'What, if anything, do these teams have in common?'. His discoveries are insightful because they are unexpected but when you hear what he figured out about what real leaders are you cannot help but think 'Of course that's what a leader is!'.
