It could be a good way of bringing on junior refs rather than be thrown in alone.
Contribute to decisions, get used to the pace of the game, the crowd, watch for off the ball stuff.

Doesn't every game have a reserve official?
Why not use them anyway?

They would need a reserve for that official.

I know already touched on this but watched two of the 3 NRL games this morning and the two refs is a must for next season the game moves a lot smoother the sooner tithe better for me

Well lets think about it! Not on Sky would require two in-goal judges with reserves. One ref with a reserve and your second ref requiring a reserve.

Eight officials for one match? We have 9 games a week not on sky.

Do the math with the current officials and see if you can meet it.

Edit: Forgot the Touch Judges!

The RFL should stop throwing money into these overseas clubs and concentrate on making our home grown rugby a better game and more competitive and better to watch
