OK, so we've all heard this before. Marc Stein is reporting that a deal between the Mavs and Nets is imminent. No reason to doubt Stein, the last time he said a deal was imminent he was right -- then Devean George showed up.
Here is latest incarnation of the deal.
Before signing Van Horn, the Mavs would have to open up a roster spot (presumably by releasing Nick Fazekas).
At this point I'm pretty certain the trade will happen. Dallas has arguably crossed the point of no return from a publicity and chemistry standpoint, while New Jersey has to know they won't get a player as good as Devin Harris if they hold on to Kidd any longer.
