Ashes 2013: we need best umpires, even if they are English or Australian, says Michael Vaughan Then later Australia's Steve Smith, I believe, was out caught behind off James Anderson. Hot Spot did not show up an edge but there was a noise. However, because the on-field umpire had given him not out, the third umpire did not have the evidence to overturn the decision. Overall I believe DRS is good for the game. It has moved cricket forward and we are getting more right decisions now. But we have to make sure the people who operate the system know the job. It sounds silly but we are in a situation where we need dedicated third umpires. It is a specialist job. At the moment one week an umpire is out in the middle, the next he is sat in a room surrounded by monitors. It is a crucial role now. It is more frustrating when the third umpire makes a mistake. We understand human error out in the middle working in the heat of the moment, but find it hard to understand why a third umpire, with all the technology at his disposal, cannot come to the right decision every time. A slight tweak to the system is required. I believe a team should have one review but not lose that review if they appeal an lbw and the verdict is umpire's call. A team is appealing because they believe the ball has pitched in line and is hitting the stumps. If a review shows it has pitched in line, and is clipping the stumps but remains umpire's call in the case of an original not out verdict then I believe it is unfair for the bowling team to lose that review. It is frustrating because later on a team may find it has no reviews left. That happened to England here on the first day. The lbw call on Smith from Graeme Swann was very tight. England lost a review and could not appeal an obvious mistake by Tony Hill later when he gave Smith not out to Stuart Broad, a ball which was hitting the middle of middle stump. Hill should not have missed that. Likewise, Aleem Dar should not have missed the Broad edge at Trent Bridge. This series has proved we need the best umpires standing in the big matches regardless of nationality. There are so many cameras at grounds it would be impossible for the umpires to get away with being biased, so have the best officials even if they are English or Australian.
