The NRL is trialling technology during the upcoming pre-season games that it hopes will finally end one of the biggest frustrations in the game; definitively determining whether a pass has been thrown forward.
Surely if the hope of this trial is to determine whether the pass was 'thrown forward' then the technology will serve no use?
A football 'thrown' forward should be easily spotted by a referee/touchies watching the player's hands. Technology can't fix that.
The technology will only be of use if the rules of the game are changed so a pass thrown backwards is illegal if the ball travels forward. In other words, when team mates are running forward in support, they probably will never be able to lawfully pass the ball.
