Sorry all, couldn't resist the title.
My question is, is there more to taking wickets at international level (in a Test match or point in an ODI when the opposition is not slogging) than accuracy alone. Is there a currently intangible penetration trait which depends on small factors such as pace off the pitch and sharpness (but not necessarily quantity) of bounce. I ask this after watching Jason Gillespie in the 2005 Ashes. Sure, he was off colour, but he lost the ability to even trouble the batsmen for more than one delivery per spell whereas Glenn Mcgrath has taken 3fors and more when off colour, just by producing a few deliveries in that troubling area which had Atherton jumping so often (sorry Richard).
...or is it just all down to accuracy and simple ability?
I am prepared for a unanimous result in the latter, but give it some thought, please...
(...or do you not have the foggiest what I am talking about?)
