Well Draft Express has him described quite well.
I have not followed Union Olimpija much lately... (so i cant really say much about his last 6 months improvement)
Anyways, i can surely say he is a tougher player and way better defensively than per say Udrih. (worse shooter, worse court vision, Dragič is faster and more athletic)
Can finish with both hands, streaky shooter. I saw him do some airballs when completely open from 3pt range but not that bad that he could not shoot a decent %. He is good at driving where he is a crafty finisher.
He could be a GREAT defender in the NBA if he would be dedicated to work.
He demolished Tony Parker on defence in Euro. (seriously... i dont know if it was also a bad day for Parker or maybe he underestimated Dragič...)
Good size for a PG. 6-4
I think it would be worth picking him early second round or even late first round. And lets say im not being a homer...
p.s.
oh... i also remembered that i wowed t him quite a few times when he wasnt afraid to go flying into the 7 footers for a rebound; fought really hard...
