Makes a good point on how DRS has revived orthodox finger spin
Before DRS, batsmen had a wider forward defence
Padding up was a lot more common
DRS forces you to use the bat
Finger spinners no longer need huge turn to get people out
In the 50s-60s you had Jim Laker, Lance Gibbs
And yes, you had Bedi, Prasanna in India starting late 60s
Someone like Underwood was a terror on uncovered wickets. Would've been far less effective had he started playing a decade later in late 70s
Men like Emburey, Shivlal Yadav made up the numbers. Not a major threat
Leg spin on the other hand remained potent. E.g. Qadir in the 80s
But these people were not finger spinners. But unorthodox doosra bowlers.
Saqlain, Harbhajan and Saeed Ajmal being the notable names
Murali was an out-and-out wrist spinner.
The present decade has seen many fine finger spinners
Graeme Swann
Nathan Lyon
Ravi Jadeja
Ravi Ashwin
All would've struggled pre DRS
Esp Swann / Lyon who don't get to bowl on v helpful tracks often
