Dallas doesn't seem to have the young assets to tempt Sacto. The do have Kamen's expiring $8m deal, so if Kings ownership wanted to get out from under Salmons' contract, for example, they could deal Cousins and Salmons and filler for Kamen, Collison, and Brandan Wright, if they fancied those two young players. That's not a great haul for Cousins.
Orlando has a number of young assets - Vucevic, Harkness, Nicholson, that would be coveted by a rebuilding team. They also have an extra 2014, 15 and 17 first round pick along with their own picks. If Orlando wanted DMC, they certainly have the assets to get him.
