It's pretty silly that it's even in question.
If he catches it he scores a try.
What player anywhere in the world at any level of the game is going for an intentional knock in that situation? Note the term "INTENTIONAL".
That's what makes it the blatant clanger that it was. Same as the very many clangers this same ref has made in the past...remember Bismark's? The literal textbook tackle that saw him sent off.
How does a professional ref, apparantly deserving of our respect, make a call like that?
I always use cricket as an example when people talk about human error. Remember how much human error there was prior to the review system? Have you seen umpiring the last decade or so...the guys are like robots. They hardly get anything wrong anymore.
So what happened? Is there just less room for corruption now? Has the review system itself helped umpires to look at things more clearly, have they been terrified into making better calls, been forced to be more objective?
Dunno what happened but there is a gulf size difference between the level of umpiring in cricket prior and post. And the dividing line was the review system.
My feeling on rugby refs is that that they get tired as the game goes on. And same as with players, tired bodies make tired minds that make bad decisions.
I've always felt that they should play more of an administrative role and there are enough angles and cameras at pro games these days for the tv ref, who generally has a better veiw of proceedings anyway, to make more calls. He also has the benefit of watching slow motion replays on the fly and making clearer calls and stopping play legitimately.
At scrum time, for example, a tv ref can see both sides of the scrum as well as a top down view. Surely he is more able to make a scrum call than the ref that is only privy to one view of it? The amount of scrum penalties that make no sense...it's ridiculous.
How about offsides? I won't mention a names but certain teams have become adept at creeping offside when the ref is facing the ruck and can't see the backline players behind him. It happens all too often and the linesman don't call it because they don't want to be seen to be interupting proceedings too much. So it goes unpunished.
