The referees back then officiated to the letter of the law and were not afraid to blow a penalty every time. The NRL has made a rod for its own back with several things and a game is now not refereed to the law it is 'managed'
*Changing rules every other season or 'tweaking' said rules, anywhere from play the ball to ruck infringements ( the close enough is good enough on play the balls ; this has been adjusted this season with a lot of penalties being given when the foot does not contact the ball upon playing it ...which was always the rule back then.)
*The referees give 'opinions' relating to things not a definitive ruling
* Referees back then no matter whether you liked them or not actually respected the players and did not act as if they were holier than thou.That respect was returned.
As to the subject of touch judges, they are there to assist the official in the centre of the ground...The touch judges have various duties; being the referees’ third and fourth pairs of eyes on
forward passes, offside calls, strips, knock-ons, general plays near the sideline, any time the ball or the player goes into touch, and to let the ref’s know if there has been a conversion from a penalty or after a try has been scored. Shame they can't even seem to do that these days. How many forward passes do they miss and how badly do they help out with offside situations in marking the ten.
This shows how they
should operate.......
