Originally drafted into the NBA, he featured in the Spurs' run to the 2013 NBA Finals but was traded to Toronto. He joined CSKA Moscow in 2014 and was named MVP as they lifted the VTB United League title, also earning All-Euroleague Second Team honours. Previously, he had three years in the Spanish league with Valencia, helping the club to the ACB Finals in 2011 and victory in the Eurocup in 2010. During four seasons in France with Cholet, he was MVP in their French Cup win of 2008 as well as the MVP of the Pro A All Star Game that same season. His elder sisters Sandy and Leila played professional basketball in France, as did both his parents.
