I was fortunate to get a copy of Scorecasting: The Hidden Influences Behind How Sports Are Played and Games Are Won, and it is a book that I have been enjoying immensely.
The book is like the freakonomics of the sports world... it looks at common assumptions in sports (homefield advantage, does defense win championships?, why coaches don't go for it on 4th down, etc) and why they are correct or incorrect. It gives strong statistical backup for all of their beliefs.
As a sports fan that also loves numbers (I am an accountant by trade), it has been a fascinating read. I have learned a lot about these commonly held beliefs, and certainly it will provide at least subtle changes to how I view sports and how I think about them.
If you like sports and like numbers, then I am confident in saying that you will enjoy this book.
