According to Mark Murphy of the Boston Herald, the Boston Celtics have listed Patty Mills as one of their free agent targets.
Hearing that the Celtics have a list of "seven or eight" free agent targets, including Spurs point guard Patty Mills. ... Discussions between team and Evan Fournier are ongoing, but not close to resolution.

This shouldn’t come as too big of a surprise considering Boston’s lack of backcourt depth. While many Spurs fans would undoubtedly be sad to see Mills potentially leave, it makes sense for him to go elsewhere considering the surplus of guards that San Antonio has on its roster.
