Isn't that usually the reverse though? You trade a longer deal for a shorter deal and then, when you can, you waive him and eat that year's salary. Saric has only one more year, anything we could do with some other guy in a trade we could do just as well with Saric.
I guess if some other team really wants Dario and is willing to swap one year contracts and sweeten it with a pick it could happen. But that's not going to happen either so I'd say he plays for us unless his injury comeback fails and he retires or something like that.
