What Philly was thinking:
They wanted Blake Griffin in their starting lineup, and really wanted a small forward. They loved Green. Now, they have a front court featuring Griffin and Green that they can build around.
They're a little weaker at center with the loss of Dampier, but he was never a long-term option anyway. At least Anderson has some room for growth.
Strangely, Philly got a player they loved (Green), LA got a player they loved (Bargnani), and I got a player that I hate in "real life" (Randolph).
