Referees in England
I was coaching today and observed the following scenario. I'd like to know how others would manage it. And whether my approach would be considered reasonable. U14s.
Yellow score a try. Blue team goes into a huddle with coaches behind the posts. After Yellow's conversion attempt Yellow are waiting to receive the restart kick. Blue huddle continues for what seems to be an age. Then Blue saunters back and the eventually restart.
What I would have done.: warn Blue to restart quickly otherwise FK at half way line to Yellow. If they didn't oblige quickly I would have awarded the FK with no further warning. And told the Blue coach to get off the pitch.
What actually happened was ref waited patiently for Blue to finish their conference and restart.
Thoughts?
