Multiple teams reportedly have kicked the tires on a potential trade for seldom-used Celtics big man Chris Boucher. The Atlanta Hawks, Philadelphia 76ers, Phoenix Suns and others have shown “exploratory interest” in Boucher, according to a report Wednesday from HoopsHype’s Michael Scotto. His 91 minutes this season rank last among all Celtics players, not including those on two-way contracts. Queta and Garza have held up well in their respective roles, lessening the Celtics’ need for center help. They still could look to upgrade the position, however, ahead of next Thursday’s NBA trade deadline.
