Reebok Pro Summer League
The Reebok Pro Summer League, known originally as the Shaw's Pro Summer League, was a professional basketball developmental league hosted by the Boston Celtics of the National Basketball Association (NBA) during the league's off-season at Clark Athletic Center on the campus of the University of Massachusetts Boston. Founded in 1999, the league planned a 2004 season, but was forced to fold due to the 2004 Democratic National Convention, which was being held in Boston.
