Do you have Moneyball fever? Non-American readers, let me explain: Once, there was a baseball team. It had little money. (Unlike in the IPL, where salary caps limit what teams can spend on talent, the MLB lets rich teams outbid for prize athletes.) So, the team’s manager uses statistical analysis and finds a new way to predict a player’s value. In doing so, he finds all sorts of hidden gems that carry the team to the top.
Why do I, a non-baseball fan, care? Two questions: 1) Are conventional ways of evaluating cricketers all wrong? 2) Is cricket ready for a similar statistics revolution?
1) I have long argued, for example, that good fielding is overrated. Once you cover the basic stuff — catch well, throw well, run well — I don’t think a good fielder adds that much. I’d rather have a good batsman with Munaf Patel energy than an average batsman with excellent fielding skills. But there’s a broader question at stake: do we know how to predict a good cricketer? For example, is a batsman who rotates strike often better than one who drops anchor and tires the bowlers out with a solid defense? Is an economical bowler better than a strike one? Or take T20: would you rather have Jacques Kallis, or, say, 4 players who can hit 30 runs off 15 balls?
2) Can statistics really work in cricket? Baseball seems more one-dimensional; in a cricket line-up, you need a variety of characters. The openers have to be solid in defense; the lower-middle needs to be able to ramp up the pace, etc. Then again, I once had a math-minded professor who liked to try and predict what a batsman would do with each successive ball, and more often than not, he’d get it right. I’m sure the betting types are basing their values on some sort of modeling, yes? But has anyone read of a team that uses statistical analysis to try and a) value particular athletes; b) predict particular outcomes; and c) base strategy around the numbers?
UPDATE: Of course, the English are on it. Via The Old Batsman:
Ever since Lewis’s book, every sport has tried to find its version of Moneyball. Andy Flower found Nathan Leamon, a mathematician from Cambridge University who was also a qualified coach, and provided a well-funded black-ops stats department at the ECB for him to use [it's easy to imagine A-Flo wrapping an arm around Nathan's shoulders and telling him to 'think the unthinkable...']…
[Leamon's] gone to town and then some. England’s enthusiasm for Hawkeye extends way beyond the DRS – they’ve used to it log and analyse every ball delivered in Test match cricket around the world in the last five years.
With access to such vast data they now run simulations of every Test match they play, taking into account venue, conditions, selection and pitch. Leamon reckons that such ‘games’, when he checks them against the actual matches, ‘are accurate to within four or five percent’.
Other work has been in breaking down pitches in areas for bowlers to aim at: Leamon claims England’s palpable success against Sachin Tendulkar was due in part to statistical analysis that showed Sachin made the bulk of his runs on the leg side until he reached fifty.
