Adrien was out of basketball during the 2015/16 season. He found himself in several run-ins with the law in his time away from the NBA, including one where he was arrested for stealing a Mercedes from a valet. In a separate incident, he was arrested for getting into a physical altercation with a hotel security guard. He was later arrested again for refusing to comply for police during a routine traffic stop in which Adrien lost his cool and pushed the arresting officers, per TMZ.
Adrien previously played overseas for the Guangdong Southern Tigers of the Chinese Basketball Association during the 2014/15 season. He was with the Pelicans for their training camp last fall, but was waived prior to the season. In six seasons since going undrafted out of the University of Connecticut, Adrien has played for five NBA franchises and he sports a career player efficiency rating of 15.0.
