Nothing will change with VAR until they have to document the reasons why some of these questionable decisions are made.
Whether it is incompetence or corruption, they just hide behind silence. Media such as MOTD and SKY just seem to let is slide and I don't get why, any managers that speak out are slapped with fines. It is becoming worse and worse, lack of consistency and I really do believe the tech is not there yet. Low res footage which in no way can pick up the point a ball is struck, when looking for a offside. If the video shows the ball as moving, it is too late. That could be 20,30 or 40 frames, you just cant make calls on such tight decisions with those levels of error.
After each game, there should be a review written of each VAR decision and how they came to the result they did. Explaining the penalty against us and the non-check (may be they did) of the handball that lead up to their 2nd goal, would be interesting. I guess the problem for them then is that it will be easier to pick up on inconstancies from game to game, maybe even within the same game.
I know being at a game and having to endure these decisions is not entertainment at all. Richys disallowed goal last week is an example. It took far too long and the margins were so tight it was ridiculous. It seemed there only agenda was to check and check and check until they could disallow it..
