Having seen the highlights, I'm bewildered, to put it mildly.
Livermore's challenge is a red for me. It's a lunge, it endangers the opposition, and he wasn't in control. As I posted on page 5, that means it's a red. No complaints.
The Hause incident though. His studs go into Diangana's ankle/shin. He clearly endangered Diangana,, and I can't believe it wasn't a red. That said, if it's only a yellow, play the advantage. We had one shot on target all game, and the one time we get a 2v1, the ref brings play back. It's all ifs and maybes, but if play was allowed to go on, then we might have scored and they might have got a red too.
I'm not one to subscribe to some sort of conspiracy - I am a big believer in Hanlon's razor "That which can be attributed to incompetence should not be attributed to malice" - but I always thought Atkinson was one of the better refs, and in that five seconds he's made two errors (should be a red, if only a yellow, play advantage).
