Bos/mem/dal trade
Boston gets: Marion, Kaman, mayo, Dal and Mem 1st
Dallas gets: Rondo, barbosa, and cash from celtics to buyout barbosa
Memphis gets: Lee and fab using their trade exceptions
Memphis gets a player they want for a first in a weak Draft.
Dallas rids itself of Marion's contract and gets Rondo to potentially pair with dirk and Howard next year. They may have enough room to go after Smith too. getting Rondo (even with an injury) is a smart big splash move I can see Cuban going for.
For Boston, you get two smart veterans that could fit easily into the c's system, a young talented scorer in mayo, and Draft picks that could be packaged with bass in another deal maybe to get Reddick for example
This is why I've been suggesting Dallas as a potential destination for Rondo. They have some nice pieces that could contribute the Cs now, with some who could also last into the future.
It would not surprise me at all to see a deal build largely around Rondo and Bass from the Cs and Mayo, Kamen, Collison and Wright from the Mavs.
We are thinking the exact same thing.... It actually seems perfect for both teams. Here is an idea I had:
