exactly.Nrl creating a bad precedent in saying the challenge was allowed.
You watch. Every game will finish with a challenge now.
They have now said that the last play (of each half) is completely different to every other play in the game in that it always ends in a stoppage, with the stoppage being indicated by a short whistle. As that is a stoppage anything between the last play the ball (or apparently kick off in this case) and the short whistle can be challenged. That means that the 'referee' should also give each team 10 seconds after that short whistle before blowing a long whistle to indicate the actual end of the half/ game.
ie, unlike any other play there is an automatic right to challenge anything in the last play.
So basically the Captain can simply say I challenge and then make something up in the hope it happens.
And if the 'referee' does not give them 10 seconds, or significantly longer if they feel like it, then they are actually negating both teams right to challenge.
Go for it Jimmy T, when there's a challenge left from here on in just use it on the last play to make a point as to the stupidity of this post-event justification that they've made up.
