I don't think it necessarily is. The Coach's Challenge for offsides was already brought up - if you have to do it millisecond by millisecond, is it really offside? It's one thing to take a frame and a ruler a measure that his foot was ahead, but they are also correlating the ball leaving the foot, with every player in movement. If the human eye can't tell in realtime, how is a player actually supposed to make sure he's onside? I wasn't really watching the game very closely and don't particularly care, but my own feeling was it was a waste even sending either of those for review.
There have been plenty of examples this year of offside plays that VAR shouldn’t overturn.
There’ve been a couple of armpit vs arm debates, some where they had to zoom in and try to divine which pixel is the one that counts, cases where a player moved further than the offside margin in a single frame, etc. Plays where the current technology isn’t capable of delivering an objectively correct decision.
This wasn’t one of those.
He was offside for a frame or two before the one it counts on (first frame the ball is on the foot), he’s well outside any reasonable “grey area” that might exist based on image quality, and there’s no debate over where the line should be.
When you have video review, he’s clearly offside:
The only argument about it would be if you’re arguing frame by frame should never be used for offside, which is a different argument and something that no league has chosen when implementing VAR. In every league that has VAR, that’s offside.
I totally get being upset at VAR (Kavanaugh really since they were his decisions) for the other two calls, but being mad at VAR for the offside is just being salty.
