The English Premier League showed just how bad replay officiating can get.
Short version:
--Liverpool's Luis Diaz scores an apparent goal.
--VAR officials tell the ref to delay while they review to determine if Diaz was offside.
--They use the replay to see that Diaz was clearly onside, and the goal is good.
--They send down word to the ref confirming his on-field call.
--As play restarts, the VAR officials quickly realize that the on-field call was that the goal was disallowed because Diaz was called offside, and they should have overturned that call, but it was too late to do anything about it.
