Hi taraz. I am a rugby referee and was destined for professional levels until I was robbed with my back injury. The system was bought in to make sure the right decision wins at the end of the day. There are fortunes to be made and lost and careers hinging on decisions. It is crucial to get right and technology has allowed this to happen. I understand it has taken away conversation pieces from mates but it stops cheating. referees never had the respect of the players because they weren't professional and could hoodwink them, not any more.
