I think we have moved away from an original concept of having the ref have final say. His interpretation of the rules was final. Refs having absolute power is ok, but not when they make so many mistakes, so we introduced an extra ref, but the mistakes kept coming. We increased technology with various camera angles, and with it we could see even more mistakes by the refs, so bunker officials who had playing experience were introduced, but again they failed to solve the issue. These bunker personnel were replaced by refs who had a better eye for the rules, alas, we still have not solved the problem.
So what is the actual problem?
As we have continually focussed on the rule book and the transferring of the final decision, we have also somehow lost sight of the spirit of the game and with it refs have either lost a feel for the game or are reluctant to adjudicate by instincts.
I saw Townsend run past the flight of the ball because he only had eyes for Brooks, as he got up he was yelling at the ref while pointing back at Brooks, while on the other side Feldt was doing the same. Why didnt the ref, after referring to the bunker, then make a decision on the available evidence? Why do we have bunkers decisions overriding the ref's, when the bunker doesn't have anywhere near as much information as the ref does?
