In 2012, seven adidas EUROCAMP players were selected during the NBA Draft including first-round pick Evan Fournier of France – the No. 20 overall selection by the Denver Nuggets.
The camp was staffed by 10 NBA assistants - none of which work with the Warriors - as well as former Warriors favorite Sarunas Marciulonis.
