Returning to Boston, where he spent two back-to-back seasons of his 10-year playing career (2014-15, 2015-16), Turner is expected to focus on player development as part of head coach Brad Stevens' staff. Having been a player right up until last season (he played 19 games with the Atlanta Hawks), Turner will evidently have a fresh and modern perspective on development.
Despite there being no formal announcement of his retirement prior to this news, the move unmistakably signals the end of Turner's time as a player. The former No. 2 overall pick in the 2010 draft never quite panned out as expected, but he still managed to forge an enduring career in the league, with his most productive seasons coming as a member of the Philadelphia 76ers.
