Age isn’t anything but a number for Brett Brown when it comes to Dario Saric.

Saric is beginning his first NBA season at 22 years old. On paper he is still young, just scratching his early 20s at a point when many are fresh out of college and entering the workforce.

But Saric’s athletic history dates back to his teens. He comes to Philadelphia with a lengthy tenure on the court.

“He sort of contradicts his birth certificate in that his basketball experiences are rich,” Brown said Thursday at his annual media luncheon. “He’s not a kid. He’s no kid. He’s 22, but he’s no kid.”

Saric started his pro career in 2009. At the age of 15, he played for Zrinjevac in his native country Croatia. It didn’t take long to gain international recognition. His accolades include MVP of the 2010 FIBA Europe Under-16 Championship and 2012 U-18 Championship, as well as consecutive winner of the FIBA European Young Player of the Year award (2013-14). Saric also recorded a double-double in the 2012 Nike Hoop Summit against a USA team that included Nerlens Noel.
