Should the AFL invest in HD, slow-motion goal line cameras?

The goal umpire had the best view - he was in perfect position and saw where the ball was touched in 3D. The 2 cameras only see the image in 2D and unless the cameras are in a perfect position right on the goal line, the view will be distorted. That is why one camera appeared to show a clear gap between the ball and the goal post, while the reverse angle appeared to show the defender touching the ball before it had completely traversed the goal line. By the rules of the game, the correct decision was made to go with "umpire's call".

Having better quality cameras won't really help - to get a accurate read, multiple cameras are required to recreate a 3D image of where the ball was when first touched by the defender.

There was no "clear gap". Take a closer look. You are mistaking the goalpost's halo for a gap.

Prefer the AFL invested in better trained umpires (goal and field). Their decision making has been horrible this year.

Hocking changing interpretations on the fly hasn’t helped their cause either.
