I think this trade addresses the concerns and wants mentioned in the various trade related news associated with each team. It also works on ESPN trade machine.
Boston gets: Josh Smith Atlanta gets: Kaman and B.Bass Dallas gets: Rudy Gay and Jason Terry Memphis gets: Marion and F.Melo
Atlanta knows they will lose Josh Smith at end of year so will look to get a solid PF and Kaman is a big that allows Horford to play his natural position and Kaman gives them flexibility because he is a free agent at year end.
Dallas gets an all star in Gay and Cuban said he will spend the money that comes with him They also get fan favorite (terry) back.
Memphis is looking to shed salary and get do it by moving Gay. They get a less expensive veteran/proven SF in Marion for half the money and one less year. They also get a cheap young C in Fab Melo.
Boston gets their guy. A friend of Rondo but more importantly a true beast of a PF that can play alongside KG down low but also run the floor.
