I'm split on this. There was a chat in this forum about it when it was first mooted for use in international cricket
here when opinion was pretty much down the middle (and I have to note here the consistency of the posters above in the stance now, after a fair number of trials, and before it was implemented).
It would be fair to say that, initially, a lot of cricket followers were in favour of it, and certainly a lot of critics in the media wanted it brought in. I've always been sceptical as I'm not sure that using the technology brings any greater conclusivity to proceedings. On a low catch, a 2D presentation foreshortens the angle, and the decision made will have to err with that given by the on-field umpire; on an lbw shout, it is always about opinions. By not using the predictive element of Hawkeye, which may be anything from 2mm to 10mm out depending on who you listen to, the 3rd umpire still only sees pretty much what the on-field umpire sees, just in slow-motion a number more times.
Sure, there may be some occasions when a close bat-pad/pad-bat opportunity can be reversed on the evidence of a TV replay, but then if you've used up all of your referrals anyway, the 'injustice' of an incorrect decision will still stand.
Another massive point to consider is that the players are unhappy about it - at least, that is the opinion given by Mike Atherton and Nasser Hussain when discussing the matter both last night and this afternoon on SKY Sports. It was definitely the case when it was trialled in the televised matches in the Friends Provident Trophy domestically, and captains refused to use it because they didn't want to undermine the umpires authority.
My conclusion would be to trial the system used in the Stanford 'Super' Series - it may be the only good thing to come out of that week - and give the power to the umprires, whether that be the on-field umpires or the 3rd umpire. That way, the players don't have to challenge the officials' authority, the gut feeling of the on-field umpire can hold sway, and if the 3rd umpire sees an obvious nick, he can rapidly bring it to the on-field umpire's attention.
In February, the ICC released this statement to
Cricinfo, explaining why they don't use it currently:
The approach used during the Stanford Super Series has been considered in the past, but several factors make it appear inferior to the current decision review system. Some of them are:
1) It might take longer than the current method.
2) It could be impractical. The third umpire would have to watch at least one replay - and there's no guarantee that will be conclusive - before indicating he felt the decision should be changed, by which time the batsman might already be halfway to the pavilion.
3) It could actually provoke dissent if players stood their ground after being given out - or bowlers stand mid-pitch after an appeal is turned down - waiting for the TV umpire to start watching replays.
4) It would diminish the authority of the on-field umpires more than the current trial, as it'd be the TV umpire who'd have the final say, not the on-field officials as now. It could see the on-field officials relegated to ball counters and clothes horses. That was what happened in the Johnnie Walker Super Series in 2005, you may recall: umpires had the power to refer to the TV official and ended up referring virtually everything.
I would suggest: the current method is hardly speedy, so it's unlikely to take any longer; any obvious decision - which is what the ICC claim to be trying to stamp out - would be so by watching the live action on a monitor (did anyone watching TV think Chanderpaul was out yesterday, other than Daryl Harper); I don't think there would be any great shows of dissent - most cricketers accept the umpire's decision, although this may be a fair consideration; finally, the final statement contradicts itself - the system can only diminish the on-field umpires if they have no say in what is referred, and if that is the case, then they won't be referring everything.
One final comment: fair play to Nass for asking Alan Hurst, the ICC Match Referee in Barbados who actually put up a good fight in trying to defend the current system, if he thought Daryl Harper was incompetant - no letting the officials off lightly there!
