I was wondering something similar on Saturday, how far back in the passage of play can a goal be disallowed. An example was a Brighton player might have been fouled on the half way line but the ref didn't blow, Watford then come forward on the attack. Had they scored following three or four passes and a pass to the winger who crosses the ball to a striker to score. Would VAR go all the way back to the half way line challenge or is that no longer material as the ball didn't go in the net until 7-8 passes later and plenty of chance for our players to win the ball back or block the cross.
*Fnarr, chortle*
Viz aside, yes I agree. It's getting silly.
