What do the most dominant teams in sports history have in common? That’s the question Sam Walker asked and answered in this part-sports, all-leadership book. He combines 20 years of being a sports fan with scientific analysis of teams throughout history in a well-written, interesting book that can help any team or leader. Even though the book breaks down the indispensable qualities of the 16 best sports teams of all time, this really isn’t a sports book. It’s a leadership book whose setting happens to be the sports world. Here’s the book in a sentence: It’s not the quality of the players nor the coach on the sideline—it’s the captain of the team that makes the biggest difference. As you read through these notes, here are two things to keep in mind. 1) The lessons here are transferrable to all teams. If you’re part of a group of people working together, there is something you can learn here. 2) One person on a team can make a difference. If you’re the coach, the superstar, the captain, or a player, you can make a huge difference.
