"Mitigation" here is complete rubbish. Owens didn't wrap his arms and just used momentum to throw him over. Extremely dangerous. Video replays look bad from every angle. The fact he landed on his back was pure luck, nothing more, and every action in the tackle by Owens was reckless. It's quite idiotic if they want to use the precedent of dumb luck to decide a player was more or less reckless. That tackle really should be a red card, if World Rugby are fair dinkum. Which they are not, on evidence thus far at this World Cup.
