I'm not a big fan of Dario Saric.
He's a 6'10" SF with handle playing in the top Euroleagues since he was 15 and won the 2012 FIBA under 18 championship MVP and won the Croatian League finals MVP a few months ago. If he somehow got on the Spurs he would be an all-star within 3 years
Saric is a high iq player with nice size for SF. But he can't guard NA sfs. Does not really have a position in the nba
