Unlike Graeme Smith, I don’t have a problem with some Test series including UDRS, and others not. There’s nothing inherently unfair about that, as long as both teams head into a match know the rules and what to expect.
The underlying assumption — much disputed by the BCCI — is that the UDRS guarantees a higher quality of umpiring and cricket. I’m not sure, and Sambit Bal excellently summarizes the points against the current system: 1) HotSpot and Hawk-Eye/Virtual Eye are not fool-proof. 2) The two allotted reviews to each side isn’t ideal and 3) the system is skewed toward batsmen, who really don’t deserve any more help.
Remember these numbers: 89-32. The first is the number of unsuccessful reviews last year. One assumes that another layer of review is an automatic improvement, but that’s not always the case — so relax, and play the fates, as all good cricketers learn to do.
