not quite sure I understand that.
but the scenario I don't think is fair is --
- knock on, adv blue
[a little time passes]
- peep no advantage, scrum blue
- peeeeeeeep End of game.
How come? Well, blue, while you were playing on and I was waiting to see if an advantage might come ... alas time expired.
No, no apologies mate, it's a policy of mine, pay no attention to the clock. you should have been able to guess that might happen.
Yes, I know you can't see my watch, don't care.
What is a little time passes? Time doesn't pass without action! If >10s, and a lot can happen in 10s, it is no side after the next stoppage. We cannot capture all those ponderables in simple posts on a forum.
If they drop the second pass then likely yes come back but would you blow as they were just mounting an attack down the blindside with a 3v1 and bring them back for a scrum on the basis there was only 10 s on the clock? As
@Ciaran Trainor observed they then get pummelled in the scrum!
As a player I would much rather we had the full opportunity to go forward and were found to be short in skill or execution than come back and get hammered in the scrum and then find we are scramble defending our 22 as the red 8/9/10/11 attacked down our blindside, because the ref wanted to make sure the scrum was awarded within playing time.
Again advantage is viewed in many differing ways and does not equal blue scoring; if they made 40 metres and then fumbled or were tackled into touch, they have had a very real opportunity.
Or maybe the developing attack draws the red defenders into a penalty offence, see Yellow card for Samoa nine yesterday for a prime example of stupid offences defenders commit when under pressure.
Going back to the start point, would I accept that this was advantage over and time expired, even if the ref hadn't called it? It depends!
But the beauty of advantage is that is it not fixed, it is always a situation specific decision and it allows great empathy for the outcome of the game to be decided by the players.
