The book is about a baseball player Billy Beane who didn’t fulfill the exceptions as a MLB player but later became the general manager of Oakland Athletics. The big idea of the book is the team management by data and statistics rather than no-sense opinions. That’s how Beane revolutionized the way people thought about managing a baseball team.
It helps a lot if you know the plot and characters beforehand especially if you are listening the audio book. It’s good choice to watch first the Moneyball movie starred by Brad Pitt. Personally I watched the movie afterwards… If you want to think outside of the box and leave the this-is-how-it-has-been-done-before approach behind this is you book!
