We could realistically go after developing our talent.
Lets leave Josh Smith out of this. We now have more chips now than the KG megadeal days. Between..
That's an impressive list of talent excluding are big three. Who could we realistically go after?
While I agree that keeping this much depth and talent is tempting (and believe me, I'm more excited about this C's team than any team since '08), in the current NBA depth doesn't win championships. Depth gets you good regular-season records.
Take a look at the Spurs. They dominated the regular season last year, but when it came to the playoffs, they didn't have the firepower to shut down the Thunder (and I bet they would have lost to the Heat too). I think the teams with the best shot at a title have a good amount of superstars with some talent behind them.
That said, we have one superstar (Rondo) and two mini-superstars (KG and Pierce, at the stages of their careers). I think that's why everyone wants someone like Josh Smith: another guy who has the potential to just go off against the opposing team.
Still, Doc's a genius. He could make this current team work.
Josh Smith is not a superstar. In any case, you're not even getting a Josh-Smith-type of player for the combination of over-the-hill veterans and future maybes.
Best chance is still to try to develop what we have, and what we have (that is developable) is not _that_ much -- Sullinger, Melo, Bradley. The rest are established veterans at different stages of their careers, which are untradeable and/or are not getting you a star in return.
