just look at 100+ wicket takers and see how spinners and pacers fare on the wkpm stat. you might be willing to change this assumption of yours after that
it is not true.
some merely good pacers like mcdermott and hughes fall in this range too.
NO
Not true.among pacers lillee, steyn and hadlee averaged more than 5 wickets per test. How many spinners other than murali average more than 5 wickets per test from this era? not even warne does that. even good/great spinners fall in the 4-4.5 range. there are a lot more 4.5 wk/test pacers than spinners. there is no evidence to your claim that spinners take more wickets because they bowl more. it is not true because they need 12-15 balls more to take a wicket compared to a pacer. so their higher workload doesnt necessarily mean they end up with more wickets.
warne and murali are freaks of nature. bigger freaks than lillee and hadlee and steyn happen to be in their fast bowling community.
Of course spinners' higher workloads don;t necessarily mean they'll end up with more wickets. But great spinners will,on average pick up more wickets, because theyre
great and bowl marathon spells. This is not a phenomenon unique to Warne and Murali. Other ATG spinners like Grimmett, Tayfield, O'Reilly all picked up tons of wickets... well over 5 wickets per match, in some cases like Grimmett, over 6.
And bagapath, taking a look at the top 100 wicket takers doesnt really prove anything. Great spinners have always been extremely rare. At most 1-2 come out each generation. And I'm only talking about the very top tier of spinners... Warne, Murali, Grimmett, O Reilly, Tayfield all picked up tons and tons of wickets because 1) They were great, great, beyond epic bowlers 2) They were spinners
It's quite obvious to me that we will never ever have a pace bowler who will pick up 6 wickets per match. It's just not possible. But I'm pretty sure we'll get spinners who'll get 6+ WPM like Murali, because it has happened before, though rarely. IMO, Lilee and Steyn who average 5+ WPM despite playing their whole careers in reasonably strong bowling attacks are freaks too, as freaky as Warne, Murali etc.
