It is unclear what is going on with the GSW, but the change in general managers coupled with a bunch of poor long term contracts is no doubt playing a big role.
More to the point, the fact that teams like GSW (Belinelli), Memphis (Warrick) and Milwaukee (Villanueva) are practically giving their young guys away for free or for expiring contracts should point to something bigger: namely, the economy is really running havoc on some teams' finances. This could be an opportunity for teams like the Cs which have expiring contracts (and, presumably, the financial wherewithall to withstand the economic troubles).
