If a bad call went your way, you can still admit it was a bad call.

Being honest about a decision you benefited from is rare in sport, mostly because nothing requires it. The result stands either way; the official will not change it and your team would rather you said nothing. Admitting it separates your view of what happened from your interest in what happened, and that separation is most of being trustworthy.

Say it quietly and without theatre: that one was wrong, we got lucky. You do not have to refuse the point or make a scene about it. Just let the record in your own mouth match the record in your head.
