Firts of all, you don't keep Douglas. You trade him for anything you can get, whether is a young backup pg, a pick or both if you get lucky. To me, Douglas has no future here.
I would re-sign Billups at a lower rate if he is up for it both for the amount and for his health. If not, time to be creative.
I'd try to sign a young center like Jordan. Not gonna be easy, especially if we want to keep flexibility for Deron/CP3 but we can't waste another year of Stat/Melo prime. We really are depleted, as we need a starting C, PG,SG as well as a decent backup PG and C.
Can we trade Balkman for a pick, even a second round one? Can we turn Jerome Jordan into a serviceable backup C? Will we ever get something from Rautins or man up and trade him? Can we take advantage of having Brown and develop him to be a main card from the bench?
This is where we are right now, considering the guys that should return:
Starters:
PG-
SG-
SF- Melo
PF- Stat
C-
Bench:
6.
7. Shawne Williams
8. Landry Fields
9. Ronny Turiaf
10. Derrick Brown
11.Jerome Jordan
12.
I1. Anthony Carter (More of a guess, but a veteran backup PG who still has something in the tank doesn't hurt here.)
I2.
I3.
Filling those blanks with solid players will be tough for Donnie.
Now, some of the missing ones are obvious goners, like Jeffries, Balkman (if he can get traded), and Sheldon Wiliams. Douglas, in my opinion, is a lost piece since he can't play PG to save his life, isn't a real SG and is inconsisent in both shootin and defense. Yes, he is young but we need consistency and solid play from our 6th man. A true backup PG would help more.
Billups is the wildcard. I want him back but healthy and at less salary. Walker is somebody I could see coming back, but its like with Doug, ther may be a betterand more consistent optin out there. And Rautins, what the heck do we have there, a 10-year projet? Time to show you belong or get lost.
How would you fill those blanks?
