Geoffrey Boycott, not exactly famed for his progressive views, has spoken out in favour of the introduction of Hawk-Eye technology to aid umpires in their decision-making.
Personally, I think he’s right. There are still a lot of unfortunate decisions made, which might have been avoided if there were recourse to replays or Hawk-Eye when the umpires were unsure.
Cricket, unlike football, would not be slowed down any further by the additional use of technological assistance (which is already used for some decisions in any case), and Hawk-Eye seems to be fairly reliable for some decisions at least. That said, such umpire aids can become a crutch, meaning every potentially contentious decision is sent to the third umpire. That WOULD slow the game down.
