That's a perfectly valid argument, except for one thing - spinners (those who bowl at 50 mph) are no real use in one-day cricket, as they're too slow - batsmen can use their feet, so even accurate bowling is not that dangerous to dispatch.
Except, of course, if the ball is turning. And fingerspinners will only turn it on a small number of wickets outside the subcontinent.
I don't see how one-day cricket can drum something out of someone when it's not working anyway - and in any case, a good bowler will be able to bowl in one way one day, different the next. For instance, bowl one way in the nets, different in the centre; one way in the one-day game, another in the First-Class.
I've never actually checked-out the records of Bedi, Chandra and the other guy away from home; think I will do in a mo.
Just to see if they really were as good as people thought they were at exploiting unhelpful conditions or whether they were just older Kumbles.
