Another change to the regulations could play into England's hands.
These days a captain can only position four rather than five fielders outside of the circle in non-Powerplay overs and I'm sure that one effect of having that extra fielder in the circle means that opposition teams like India are less likely to bowl spin at England all of the time.
For some time now David Gower has pointed out that one-day captains have a tendency to sit back on the defensive and keep five men outside of the circle - even when a new batsman comes in - either because they are bowling their part-time spinner or because their spinner wants an extra man out.
That means that there are a lot of cheap singles on offer. Now, however, the captain and bowler will have to keep that extra man in; any new batsman coming to the crease with his side struggling on 50-3 will find it more difficult to pick up easy runs.
Conversely, however, the change in regulations should benefit teams that keep wickets in hand.
Imagine that England are 150-2 off 30 overs with Pietersen and Morgan at the crease when India's sixth bowler comes into the attack with only four men beyond the ring. I, for one, can imagine each batsman saying 'you can't bowl to me with this field' and going on the offensive.
Larger scores should result and in time we may find that a sixth bowler becomes a bit of an unaffordable luxury for captains.
Only time will tell if that's the case but for now I'm sure that the altered fielding restrictions mean that we're going to see more peaks and troughs in one-day games.
