There were far too many where their guy caught the ball square on his chest. He didn't have to reach for it at all. The only way that could happen is if the ball wasn't straight, or they were stepping into the tunnel. Either one is an infraction, and the ref didn't call it once.
But other than that, I have no complaints. I think he overall called a good game. As for "adding a full minute for a scrum reset", it wasn't just for "*a* scrum reset". It was for the multiple scrum resets he had to call in the second half.
