Teodosic is not being "discovered". He is probably the best PG outside of the NBA and he won't be coming overseas unless he gets a fat contract, as he is making big money in Europe. The guy is not a good defender but there is no doubt that he would be quite a good player in the league.
As for the above debate regarding sending amateurs to the Olympics, I don't think it's a good idea. College kids would lose very early against the strong international teams and it doesn't make sense that the USA are not winning gold. I much prefer the small chance of an upset, and failing that, the best team actually winning it all. No team will ever "catch up" to USA because apart from the US being the hub of all things ball, no country is big enough population-wise, nor does the sport have enough popularity. The Aussies are doing a good job with their high performance system and will be churning out more NBA players in the coming years.
Obviously Americans are miles ahead of the rest of the world, but I think some of the sneering is cringey (I haven't seen it on this website thankfully). A more fair comparison would be an all-Europe team vs USA in terms of population. And honestly, I think any all Europe team would quite easily beat an All-NBA team in the Olympics.
