"A semanticist would have a field day parsing the differences between two related, but very different buzzwords in NBA front offices: "rebuilding" versus "retooling." In general, the former means an extended fallow period of building assets to try to contend, while the latter means ramping up more quickly toward competitiveness."

I'm not 100% convinced that Danny is going to rebuild the franchise.  He has traded for many valuable assets and it is conceivable that he retools on the fly using Rondo as the initial building block. 

What if they work a sign and trade for Smith and a big such as Bynum?  We have Rondo, Brooks, Green, Smith, and Bynum as a starting five (providing Bynum is healthy), assuming Bradley or Lee goes in the S/T for Smith.
