I voted the Hedo signing / trade just because it was such a well-schemed move in how he managed the salary cap system. It seemed so complicated, and seemed like such a stroke of genius giving us much more room to sign other players given what we thought was possible. Now we still don't know how Turkoglu will turn out and how many games we'll win, but the guy is f*cking good. he's definitely a baller.
The Anthony Parker was also arguably the best. Especially for a move that was so under the radar and how good Parker was (especially in those first 2 years with us).
