Walker starts with one of the most hotly debated questions in sports: What are the greatest teams ever--particularly those that sustained success over a long period of time. He devised a formula to compare the achievements of teams from leagues all over the world, and after painstakingly profiling thousands of them, produced a comprehensive, unbiased list of the 16 best. Period. At that point, Walker became obsessed with another, more complicated question: What did these teams have in common? A genius coach? A transcendent superstar? A groundbreaking system? Or was it all a matter of chemistry? A surprising pattern emerged: There was a very specific kind of leader at the center of these teams, a force that drove them to greatness, and they all shared eight specific characteristics. Who they are, who they are not, and the traits they shared will fascinate anyone who follows sports or is interested in building a team -- and winning. Told through riveting stories of some of the most compelling and pressure-soaked moments in sports history, Walker not only brings these uncommon leaders to life, he presents a counterintuitive view of leadership--one that can apply to a wide spectrum of competitive disciplines, particularly business.
