This ambitious study of major league managers since the formation of the National League applies a sabermetric approach to gauging their performance and tendencies. Rather than focusing solely on in-game tactical decisions, it also analyzes broader, off-the-field management issues such as handling players, fans, and media, enforcing team rules, working with the front office, and balancing pressure versus performance.
This book has the worst writing I can recall reading outside of a comments thread. There are several references to a Bill James book on managers, which I wish I had read instead. This book, with the moderately interesting premise of comparing managers across various statistics like whose teams hit the most home runs or had the most intentional walks or the like, seems almost completely ancillary.
