I'm with Larry on this one. From the perspective of the new ownership of the Kings / Supersonics, it makes sense to hold onto DMC until around the time of the draft, and then try to trade him to a team with a top 2-3 pick.
That gets you a new player with lots of "potential" to market as the fresh face of the franchise to a new, excited but understandably leery fanbase.
If you're a team like, say, the Cavs, wouldn't you trade a top 3 pick that would get you Nerlens Noel or Shabazz Mohammed for a more established talent like Demarcus Cousins? That's exactly the sort of situation Demarcus needs -- a team where he can be one of the main guys, but not THE main guy. The franchise is already committed to Irving and Byron Scott. Demarcus would come in knowing he's important to the team, but he's not the most important guy on the roster, or the most talented.
