We go into the next season with these players for sure:
Rondo
Bradley
Pierce
Stiemer
JJJ
Moore
I would offer a multi-year deal to the following players, at or their value now (though I'd prefer one year):
Bass
Pietrus
I would offer a multi-year deal to the following player, below his value now (though I prefer one):
KG
I would offer a one-year deal, at or below current market value, for the following players:
Ray
Sasha
J Green
I would let all these guys walk:
Dooling
Quise
Wilcox
My preferred roster without draft picks, any signings or trades:
1 - Rondo, Bradley, Moore
2 - Bradley, Pietrus, Sasha
3 - Pierce, Pietrus, Green, JJJ, Sasha
4 - Bass, Green, JJJ
5 - KG, Stiemer
I think this roster is more than possible to put together at a reasonable price, while keeping maximum cap flexibility for 2013-2014.
The two wildcards here are KG and Bass. KG is worth a 2-year deal in my opinion, at $12M per. He will definitely get an offer north of that in Free Agency this offseason. He is playing too well, and could easily be the final piece to a championship team. Bass is having his best year ever in the NBA, is in great shape, and is just young enough to get one more big multi-year deal. I honestly think Bass will depart, but KG might just stay in Boston at a discount if we have a competitive team.
So if you remove Bass, we still have Green and JJJ, along with KG, at the 4. If we lose KG too...we have a lot of work to do.
But that is the shell to build off of.
