... But my guess is that come March 16th, we will have a very different roster than we do today.
I don't think they will - nor they will have to - trade RR next month. They team rebuilding is planned to be done, calmly, for the offseason. They probably didn't have any hight expectation from this season, which is like a farewell for the 2008 era.
I'm throwing some numbers for a possible scenario. The actual roster total salary is $79.5MM (source: Hoopsworld, this is without counting Wallace and Shaq sort of severance wages). From the actual roster, only 6 players have contracts for next season: RR, PP, JJJ, EM, AB and BB. These contracts amount globally for $35.5MM so this leaves 8-9 spots and $44MM open, supposing the next year they will pay the same amount of money as of this season.
From the other current staff, if they resign RA and KG for the kind of money JO made this year, this will cost another $10MM. And of course, JO will go home, does not matter how little money he is willing to play for.
If they can resign CW, GS and MP for the same kind of money they made this year plus the 20%, this will amount for another $6MM. In my opinion, they won't offer anything to KD, SP and MD.
So far, we have 11 players: 4 G, 6 F and 1 C, and we have spent from the original $79.5MM:
$35.5MM plus $10MM plus $6MM = $51.5MM
This leaves them with 3-4 free spots in the roster and $79.5MM minus $51.5MM = $28MM available to spend in new contracts.
Then, with $28MM, they will have a very good chance of making a shot for a way above average Center player plus two other good players. For reference, this is what top centers around the league will make (according to actual contracts) for next season:
Chandler $13.6MM,
Bynum $16.1MM,
Noah $11.3MM,
Mark Gasol $13.9MM.
