Well, there is the July Moratorium from July 1 to 10 during which he can't be traded, so I would bet any trade being official before July 11.
Let's do a poll on when he will be traded.
Hah. My only thought was that Deron isn't going to want to wait around once free agency starts. Nets will have a fire under their butts to make a move. So maybe it happens a little after July 11th. At the time of creating this thread, everyone was kinda accepting that Dwight was staying put. I felt like people were blind to the real story (Dwight's a punk and the situation was far from over). We'll see what happens.
I still personally like my crazy hypothetical (that can never really be realistically considered until the Heat eliminate us) of trading Rondo and both picks to Orlando for Dwight and then using our cap space to sign Deron Williams. If KG and Ray come back for the vet min we can trot out PG - Deron, SG - Bradley/Ray, SF - Pierce, PF - KG and C - Dwight. One can dream.
