I know the Celtics have been very interested in getting Cousins who acts like a 10 year old. Him being on a team of almost all veterans could probably help him grow up and would net the Kings/Sonics some serious trade compensation. Rumors of Rondo being moved are coming up again but he comes up at every trade deadline so who knows what would be involved.
Kings current roster is pretty young with solid potential. Tyreke Evans can be an allstar when he wants. I am a huge Kansas fan so I know all about Thomas Robinson and he will be a star. His heart/head are in the right place. For an up and coming team the Sonics will get a pretty solid team.
Trading him for picks would also make the Kings (Sonics?) suck temporarilly and get them a high lottery pick. Like how we got (ug) Durant.
