"Stefan has a very positive upside as he matures physically and adapts to Division I basketball in America. As a big, he will give us an excellent shooter and ball-handler, who is developing his low post game," Morrill said. "Stefan is a very good student who understands the value of getting an education. We are confident he will have a very solid career at Utah State."
He is the son of Ana and Darko Rosic and intends on majoring in international business at USU.
