Just saw in the following article on RealGM:

http://realgm.com/src_wiretap_archives/53494/20080710/clippers_renounce_five_including_livingston/

that Dan Dickau, Shaun Livingston, Boniface Ndong, Smush Parker and James Singleton have been officially renounced. The timing of this strikes me as a bit odd, since now that Brand and Maggette are gone the Clippers shouldn't need to renounce anyone to sign Davis. 

So I'm wondering if this might mean that the Clippers are maximizing cap space in order to make a big offer to Smith or Okafor? Then again, it's not like the Clippers were expecting any of these 5 to play significant minutes this year (and of course they can still sign Livingston despite renouncing him).
