Sport is a business. I mean that figuratively as well as literally: profit can be measured in dollar terms but also in percentage of wins to losses. Fans seem to forget that. In business, consistently exceeding expectations is an even better thing than winning the World Series, because it necessarily means you've made MONEY. If you're the favourite and you win the World Series, you have only met expectations, and you may even have made a loss.

If baseball were a perfect market, it wouldn't be possible to exceed expectations over a long period. Over a few games, maybe - that could be a fluke. Over two seasons, it almost certainly couldn't be. That means two things: (a) conventional wisdom about the value of certain baseball players and certain attributes is wrong; and (b) The Oakland A's have worked out what is right, or at any rate their model is better than the conventional wisdom.

This is the sort of thing Billy Beane should have kept as quiet about as possible. Michael Lewis' book ought to be a Eureka moment for everybaseball manager: if it is, then the market mis-pricing will disappear,everyone will acquire players on the strength of the new valuation methodology and the Oakland A's will gradually fall down the rankings to where they should have been in the first place, given their budget. I dare say that has already started to happen.

Line 15: Line 15:
What it ought to do is open eyes of managers from other codes, and indeed other businesses: The key is in having sufficient data. If you have enough good quality data (like baseball does) then if your analysis of it is better than your competitors, then as long as your approach is disciplined and consistent, you will, over time, turn a virtually risk free profit. It's called arbitrage.

I haven't even got onto the fact that Michael Lewis is one of the most insightful and witty writers writing in business at the moment, and this book is a pleasure to read from start to finish, notwithstanding my ignorance of its subject. I have read a number of business titles recently, and compared to the rest of the pack Lewis is, if you'll excuse the pun, a major leaguer amongst amateurs.
