I can't really argue with that.
Go for corner unless the 3 points are either easy points, or substantial (like the 3 takes you in the lead near the end or to a 2 score lead to secure victory etc).
Ireland did just that against us, went for the posts 3 times. Fiji against us refused to take 3 points twice, even when one of them was literally right under the posts. Found that quite nice of them, they could of easily gone 'F U you are not nilling us'
