Veteran NBA guard Marcus Thornton has signed a G League contract and has been acquired from the available player pool by the Pistons’ affiliate, the Grand Rapids Drive, a league source tells Adam Johnson of 2 Ways & 10 Days (Twitter link). The G League’s official transactions log confirms the move. This Marcus Thornton should not be confused with the Marcus Thornton who was selected 45th overall in the 2015 draft by the Celtics — that former William & Mary guard, who has not appeared in an NBA regular season game, is currently playing for the Canton Charge, Cleveland’s G League affiliate.
