I've read many books on sports betting. I've read many books on statistical modeling and data science. I've yet to find a book that blended the two together...until now. When I first heard this book was being written, I was dubious. Why would someone write a book to the masses that would clearly give away a competitive advantage that the author enjoys? Perhaps the reason is because the author is not a good modeler and wants to make a quick buck? After reading this book, I clearly see I was mistaken to doubt the author's proficiency in sports modeling. In fact, the author addresses why he would write the book right from the start.My next concern was if this book is "too good" it's going to hurt my competitive advantage as a professional sports bettor. The author is very generous with providing template spreadsheets to work with and showing his work. However, if you've never attempted to create a model in Excel, you're going to feel a bit lost in this book. This is a good thing. You shouldn't want to be spoon-fed everything. There's a great satisfaction in learning by increasing your understanding gradually. This book will definitely speed the plow for the sports betting modeler. It'll make you aware of concepts and how they can be leveraged. It won't do all the work for you. I started making my first Excel models back in 2004. If I had this book anytime in those early formative years, oh the places I could have gone. Instead I learned many of the concepts in this book through good old trial and error over the years. Lots of error.If you're going to read this book make sure you have a passion, or at least a strong curiosity, about sports betting modeling. This book is targeted for a person who understands sports betting and understands the basics of statistical analysis but hasn't bridged the gap yet.As for the advanced bettor who already utilizes some sort of quantitative analysis for their betting. The author points out in the chapter titled "The Benter Boost" that you should always be looking to read as much as you can about other attempts people have made to solve sports modeling problem. I agree with this. It's why I'm always willing to read books on sports wagering. It's also why other pros who might think a book written about Excel is a bit beneath them should also buy this book. Even if you develop with other analytical tools like Python or R, you can find value in this book.Overall, I think this is a strong addition to any sports betting library and one which I'll probably read again a few times when I'm looking to expand my approach to a modeling problem.
