The point is that there is a structural flaw in the goal review system.
Every goal is reviewed by the video umpie before the ball is bounced whether a review is called for by the field umpires or not. There are times – admittedly uncommonly – where the bounce is held up and the decision reversed on review.
There is no mechanism, however, to review an on-field point decision, even though the outcome is exactly as critical.
Of course it's harder to do that given the lack of time, but surely the video ump should halt play to review when there's a reasonable possibility the original call was incorrect. The field umpire can, so why not the video umpire?
The most egregious example was last week when a clear Bulldogs goal against the Eagles was mysteriously called a point (the ball was a foot at least over the line when it got slime on it) and no action was taken.
With all the other mechanisms in place to ensure correct decisions on goals and points, this anomaly needs fixing.
