For any Australian in Rio these past two weeks, the most valuable personal asset is humility. This is no less true for the sportswriter as it is for the athlete and the supporter, if for quite different reasons.

The temptation - in fact, the job description - is to bluff and fake instant expertise. But there comes a point where all you can do is bow your head and plead for mercy.
