Umpiring errors and DRS
In the Guardian, Mike Selvey suggests that it is actually the impact of the review system that has led to more errors when it isn't available

There have been plenty of talking points during the India-England series, not least the absence of the DRS which has coincided with some poor decisions from the on-field umpires. In the Guardian, Mike Selvey suggests that it is actually the impact of the review system that has led to more errors when it isn't available.
A personal view was that even without DRS, it would be ingrained in the modern umpire to think and make decisions as if it were there. Certainly I could see no reason for the standard to drop. In fact the realisation has come that far from being better umpires because of DRS, it has made them subservient to it.
