As much as it would be great for Goulding to play NBA, i doubt he will, James Ennis was a better all round player and basically as good as a scorer and i dont think he will play NBA either.
The NBA can get plenty of guys like them at the same level through D-league, new college grads each year, etc and many of them dont get a shot, its very rare for guys to go from NBL to NBA, it s rare for any Aussie to play NBA, which is why its so good we have a few in their at the moment and a few more prospects coming through.
If you are not a first round draft pick its very tough to get a significant NBA gig, the % of players who do is low, it still happens and some have gone on to be stars but not many. Especially for those who didnt go to a US college or went to a smaller/lesser ranked college.
I think Olympic performances including against the USA would have helped Delly, Mills, Baynes (all went to college in the USA also) get a go and Bogut was a college star.
To me Goulding doesnt even make the Olympic/WC team or is battling out with guys like Gibson, D.Martin for the last guard spot and id personally take the other 2. So its unlikely he will have a major role and make a major impression at the WCs unless we have some main players pull out/get injured.
