Its possible, I think only the top 4 are locks. Three point shooting is so crucial these days. Unlike Olynyk, Kaminsky's post game is good enough to abuse smaller defenders if the other coach goes small ball on you.
That said, he probably will measure similar to Olynyk at the combine (not good).
Would you say Kaminsky's handle & dribble/drive face up game is better than Olynyk also? I didn't watch a lot of Olynyk that year, and haven't really followed him in the NBA.
