I noticed in the commentary on Saturday (it wasn't obvious to me on the screen) that Sean O'Brien was posted out in the backs to help take care of Sonny Bill while he was there. This was presumably because Farrell wouldn't be able to. I still like both he and Sexton playing. There have been quite a few exciting moves in the backs. I wouldn't call Farrell out of position Mick. He plays there for England. As for Saturday, I'd expect casualties........
