The standard of reffing and more so the video ref has been poor this year but last night was not a bad example. I think Powell is off mark there.
I'd also say that coaches who coach their teams to celebrate a try when they know it wasn't, or flap around on the floor when an opponent has a finger on them trying to con the ref for a penalty, or laying on to try and slow the ball down, should not then complain about the ref actually taking their con.
It's a fast game, with one guy in the middle trying to sift through all the antics to find a real decision. Leave them to do their job.
I wonder what would happen if Kendall came out and said if thought Cas were poor last night and that their coaching was substandard?
