I know it's egg chasing but an interesting quote from Nigel Owens, the best referee in the world in today's Guardian...
Trial by slow-motion replay, though, does concern him. “Technology has its place in the game, but it’s being used too much. They have to be very careful it’s only used as a last resort. So much of rugby is a grey area. You’ve got to use your experience, empathy and interpretation to decide whether that whistle needs to get blown or not. The way the game is going it’s becoming unreffable in a sense because every decision is being looked at. We need to get back to the referee actually reffing the game and relying less on the TMO.”
... and TMO is light years ahead of VAR...
