Rangana Herath just completed 250 wickets after taking a fantastic 9/127 against Pakistan in an ongoing test (as I write this) played at the SSC, Colombo.
The event prompted me to check out whether this diminutive, unheralded, unsung and hardworking bowler stood among his tribe of spin bowlers.
I did a simple data comparison. Extracted the Top 20 spin bowlers (by wickets taken) from Cricinfo's Statsguru, and then calculated a metric - "Bowl Index" (copied from this source). "Bowl Index" basically takes into account both bowling average and strike rate.
Here's the formula: (runs conceded)^2/(balls bowled * wickets taken)
And then I normalised the formula to account for total innings bowled (Bowl Index * 1000/Total Innings Bowled).
The resulting data is as below:

Rangana Herath, thus far, ranks just below Bishen Singh Bedi and Clarrie Grimmet in the all-time list. Not bad at all for the Lankan spin lynch-pin whom no one expected to take over the giant shoes of Muthiah Muralitharan.
