If, and at this point it's a big if, the core is brought back next year, there are some serious changes Danny/Doc need to make.
The first, and really most important, is getting legit big to play with KG. If this doesn't happen there is no point.
Secondly, pierce needs to become a sixth man. He just doesn't have the legs anymore to be a starter and carry such a heavy burden.
With Rondo healthy, Green hopefully able to build off of this season, Bradley actually having his first healthy off-season in which he can work on his game, and the potential Sully has, I think we could have a really good team if those two issues are addressed.
We'll see how it shakes out. I really have no idea what is going to happen right now.
