Poor officiating. I was struggling at first to figure out how the ball ended up where it did but after seeing the replay that try shouldn't have been allowed.
Is Steve Walsh not watching this game? Missing blatant knock ons. Also, I can't stand how here are penalties at scrum time. If your lineout sucks then you lose the ball, if your scrum sucks then you give up 3 points.. I don't get it. Should be free kicks so the better scrumming team gets possession rather than a shot at goal. Especially as half the time it's guess work.
The only mistake i've seen him make was the "not releasing" which lead to the first try. On everything else he is being strict while giving a lot of advantage.
The scrum penalties are fine, the Japan #3 is being dominated. You can't give a free-kick for anything that happens after the ball is fed in. The only free-kickable offences are things like "early engagement", "foot up" or "not straight".
