The Boston Celtics have hired Jay Larranaga as an assistant coach, sources tell Y! Larranaga had been head coach of Erie in the D-League.— Adrian Wojnarowski (@WojYahooNBA) August 21, 2012
In addition to being a head coach in the D-League, Larranga also coaches the Irish national team and is the son of University of Miami coach, Jim Larranga. It's unclear whether he's coming in as a offensive or defensive expert, but he's a former player and has helped pro teams like the Cavaliers and Knicks with evaluating young talent. Here's a clip of Doc's newest assistant coach.
