The beauty of the captains challenge, the refs can award tries and penalties without fear of making mistakes. If a player knows he was stripped, or scored a try that was not allowed, or the player did not score when awarded the try, the play is awarded or penalised and the game moves alot faster without going to the video ref every try that happens now.
So that time saved is only used when all of us and the players on the field can see or know it is a mistake.
That is where the challenge system is light-years ahead of what we have now.
Not only do we get refs making mistakes, we also have the video man making mistakes as well.
Captains will only challenge if they are 100% positive a mistake has been made, and that is the beauty of the captains challenge.
So no more going to the video ref after every try, unless of course it is not a try that was awarded.
Look, it is the way the NFL operate, and they are a 100 billion dollar code. Do you think they would have a namby pamby system like the NRL use in place. ? No of course not, they know the best system and have it in use.
The NRL took 3 years to get rid of a cornerpost, which brought joy to the whole code, imagine the joy of the captains challenge it will bring.
