I hereby issue a request to more math-inclined cricket bloggers (hint, hint, Deep Backward Point and Kridaya and Russ): can you rigorously compare a player’s IPL performance with his auction price? The simplest method, I imagine, would be to place those two categories side-by-side. E.g.: Gautam Gambhir, $2.4 million, 378 runs (avg.: 34). The broader question is: did the amount the franchises put down make sense?
Now, I can think of at least one major objection: the rules of the IPL auction do not exactly qualify as a free marketplace. There are various restrictions — four foreign players, a certain number of ‘capped’ Indian players, etc. — that inflate the values for particular cricketers. But still: at some level, there must be some method to this madness, surely? (There’s also the second objection — why don’t you do it? Well, I’m busy. And I suck at math.)
I’ve been trying to think of a good metric that works for the IPL. Runs per million $s type stat wouldn’t work because a middle order batsman who can come in and score 20 runs in an over before getting out is highly valuable.
The method to do this is relatively well established. Have a look at the Wages of Wins, which calculates win-shares per player for basketball, and uses that to rate players. Player restrictions don’t really matter, because you can calculate total win-shares for the season that give you a player value, taking into account their playing time (as well as average win-shares that show who ought to be playing).
The difficulties come in calculating what correlates to a win: runs per resource used (can use D/L for this), runs against per resource taken for bowlers gives you a comparable value for batsmen and bowlers. You need some way of adjusting that for fielding value (fielding resource taken/runs saved/lost compared to an average fielder), which is not currently measured (maybe the teams do measure it), and is probably under-rated. Then there is assist value: the player who gives a faster scorer the strike is worth more than one who score a little faster but doesn’t; opponent match-ups, the batsman/bowler who opposes the best player hurts their own output but might still be the best option; and the complications of a chase: risk-free batting and wicket-taking is worth more in a small chase than a large one.
Then you need to compare to incomes, which is complicated by the fact that a player who gets you 0.2 wins per game is not worth the same as 2 players who get 0.1 wins per game. The latter are average and easy to find, the former is a star. Market value is not linear with wins per dollar, but exponential and goes up rapidly as a player becomes rarer.
Interesting question. Have though about it before. But unfortunately I’m busy too…
