But when does that ever really happen? Seperating economy and wickets seems rather strange to me, surley everyone can realise that they have a massive effect on each other. No matter what Richard claims wickets do restrict scoring and of course by the same token good accurate bowling is often likely to lead to wickets as batsman feel the pressure of slow scoring. There is a place for a player like Dimi who keeps (one of my very favourite players) the runs down without posing much of a wicket threat but I think it is always a bad idea for sides to be happy taking no wickets in the middle overs while going at around 4 or 5 an over, this allows teams to provide platforms in which attacks can be made later on, sides should always be looking for wickets.
Settling for 4 or 5-an-over in the 10-to-40-non-Powerplay overs is not something I'd remotely recommend, that's settling for mediocrity. On anything bar a complete runway, the best bowlers - like Mascarenhas - are well capable of restricting to much, much lower scoring-rates - 3.4-3.5-an-over, sometimes even less than that if the pitch is a bit two-paced or offers plentiful seam-movement.
As for separating economy and wickets, that is indeed something I've been at pains to point-out is not sensible. However, there is no two ways about the fact that
consistently accurate bowling is more important in the one-day game than
one-off wicket-taking deliveries. Because no, I'm afraid anyone who claims that the scoring-
rate can be restricted by inaccurate, penetrative bowling is plain and simply wrong, because all evidence shows that this does not happen. Yes, scoring itself can potentially be so, because 150ao off 35 overs is indeed the same as 150-9 off 50. Equally, excellent accurate bowling is likely to concede ~2.5-an-over if there's two new batsmen at the crease, and perhaps more ~3.9-an-over with two established ones there. But the
rate will only be kept in check by accurate bowling; inaccurate bowling will
always get the treatment, new batsman or established.
Equally it goes without saying that the best solution is accuracy
and threat, but that generally takes a) the new ball and b) an exceptional bowler. The sort that one team can not reasonably expect to have more than one of at a time - two or just possibly three if they're lucky and resources are plentiful.
