Saric may be very uncomfortable as a high profile Balkan Christian in Turkey these days. Not a comfortable environment with Erdogan backing Al Nusra and other elements in Syria, engendering a war with the Kurds, etc.
Korkmaz got drafted where he should, from what I've read, I don't see him developing into a NBA starter, he's going to be more like Stauskas, Korver, etc. outside shooters who struggle defending "2s" b/c they're not great athletes. A good player to bring off the bench.
Luwawu on the other hand sounds like an athletic "2" who needs a lot of coaching, but has the raw talent to develop into a two-way player.
