The Dallas Mavericks are acquiring Grant Williams from Boston in a sign-and-trade deal that includes former Pistons guard Reggie Bullock being dealt to the San Antonio Spurs, a person with knowledge of the agreement said Wednesday night.
Bullock, who averaged 8.7 points in four years in Detroit from 2015-2019, and a 2030 pick swap are headed to the Spurs, while the Mavericks and Celtics will receive multiple second-round picks, according to a person who spoke to The Associated Press on condition of anonymity because no trades can be finalized before Thursday.
