It was a bad night for us as you say. It was a great night for NZ rugby and good luck to them. They took us apart. Why they took us apart is what needs be pondered.
I have pondered it and that is my view. Cooper does not deserve international selection. He would never play for New Zealand. He is not good enough. I do not want him playing for us.
It's his fault because he was sinbinned. I accept that while he was on he played well. great nerve under the highball and while kicking in the face of orc booing. The he self destructed as he always does. He is not up to it.
Yellow card completely correct. Read the laws section of the World Rugby web site.
