I dunno. Haddin’s lbw was very lucky/unlucky, depending on your point of view
Though ignoring the other discussion, he got to review that anyway as there was still one left after Watson’s obligatory waste – and as discussed his review was another “waste” anyway. I have to say that to the naked eye that looked very out – as did Watson’s. The irony is that whinging convicts people are only complaining about them being close calls where the batsman should have got the benefit of the doubt having seen the Hawkeye predictions.
I remain to be convinced that it can ever be millimetre accurate predicting the bath of the ball.
My understanding (having worked with people who worked on a similar system) is that when properly calibrated it can get pretty close to that. It is after all simply relying on the known laws of physics to extrapolate the known path of the ball after pitching. In general the only balls which deviate significantly from that after passing the pad/bat are ones involving late reverse outswing, which don’t ever result in LBW decisions. I can’t recall a Hawkeye “umpire’s call” where the amount of ball hitting was less than what I’d expect the margin of error to be, Haddin’s certainly wasn’t. I do agree therefore that “umpire’s call” should be removed and if Hawkeye shows the ball clipping it is out.
Out is such a final decision for a batter, you have to be certain. A not out might hurt the bowling side but 15 seconds later you get another chance to try again.
Except you might not get another such chance for a long time – see Rogers’ “LBW” on 20 odd in the first innings.
