Thats the aspect of VAR that really annoys me, it was brought in for" clear and obvious errors" only, now every goal is actively checked for reasons to disallow it.
If you need umpteen different TV angles, freeze frame, and close up zoomed in still images etc to spot the ball glancing off an arm below the T shirt line etc, its not clear and obvious.
The whole thing needs binned, but unless the clubs get together and tell the SFA its a heap of crap, nothing will change.
