The C's certainly are much different than 2006-7. That team had players that we could expect (dream) to get better, and a high pick. We have none of that now, unless BBD has some huge upside that I'm missing, though he may get a bit better.
This team isn't going to get better from within, and has only the MLE, which is probably better for acquiring complementary pieces.
We're very good, but my hunch is that Danny will take risks to build a champion, and would break up a playoff team in a second toward that end. It's all about banners... That '80's team he is often quoted as thinking should have been broken up won 50+ games each of the next 2 years, and made the playoffs that year...
That said, if the deal isn't out there, I think Danny/Wyc stand pat and wait until it is. We're a playoff team, this year and probably next, too, but I agree in principle with the OP.
I don't think that Ray and KG are as bad as the OP, though, just that they're looking more like very, very good role players than a "big 3" of superstars. We went from great to very good. Perhaps a bench scorer and backup PG can be acqired by tinkering, and we make a run, but I think it is almost a lock that we will not go into the playoffs with the current roster.
