It’s hard to implement in a sport that is free flowing with a lack of “natural” stoppages compared to other sports that use video replay. However, given the pretty shoddy officiating at times, it’s worth a look to help get calls right that effect game outcomes. Perhaps, a video replay within the stadium of what the ref is looking at might help the fans understand what is going on.
Any good reason that another official on the pitch hasn’t been tried? Or if it has in a top flight league I’d be curious as to why it stopped.
Game moves too fast for even the best refs at times. Another official on the pitch and not just on the sidelines could help immensely.
