Seriously? Why is this an issue?
Sounds like the coach has a known personal connection with the Korean swimmer, and was showing support and solidarity with his international friends and competitors.
From my reading his behaviour sounds very Australian. And good on him. Sure maybe he could’ve just wished him well, but in the excitement and business of the day who can blame him for being a little over the top.
We aren’t really a country that expresses a win at all costs attitude, but thats the impression i get about the other team members quoted in the article. Their comments seem a bit un-Australian to me.
