Boston gets: Andre Miller, Timofey Mosgof, 2nd round pick
Denver gets: Bass, Collins
Boston gets a veteran point guard to plug into the line up and it's serviceable bench big. Sully is already starting.
Denver gets a solid back up PF who can start when asked. They also add a center just in case, obviously somewhat a throw in. Lawson is obviously the man there so Miller is to be had imo
