This is a good post, and it's a relevant post that you make - I guess I just don't think that we should be taking our lead on racial sensitivity from CSA or from South Africa's government (cos as those who know a bit about South Africa know, Zuma has been a massive step backwards from the South Africa that Mandela wanted to build.)
You would simply call them non-white players. That's how the black South Africans that I met over there would've preferred to be collectivised.
Isn't the chairman of CSA - who released the statement I mentioned earlier - a 'non white' man?
As such, if he's referring to them as coloured players I tend to think the term is reasonably acceptable.
