1st sending off was a joke , Stu as well . Ref told assistant coach to sit down , all Stu said was give us a fair go John and he sent him off without any warning. Arrogance
So just to ask again what Chris asked, why was the sending a joke? You keep repeating it but don't give details why.
As for Stu getting sent, pretty stuipd to comment to the referee after he has just given your bench a warning whether it was directed at the Assistant Coach or the whole bench. He did say to Stu that he is responsible for the Assistant and then Stu decided to comment again
