Shouting at opposition players and officials is OK imo. Shouting abuse or booing your own players is unacceptableat any time imo.Constructive comments where instructions are shouted at players is a grey area. Where the instructions/ guidance is shouted before something happens it is OK but just moaning after an incident isn't helpful, again imo.
I don't understand playing players out of position. I think we used to get a bit more communication about injuries and as a result we were more tolerant of any player who was asked to fill in. Don't think we have that level of information. Maybe it's considered a waste of effort because whatever the official line is there is a social media storm.

Given my record for predicting Dee results I will accept a 1 or a 2 rating!
