I think the way this team is looking so far this year, it might be worth it for Ainge to explore trading KG and Ray prior to the deadline to teams that could use them in the playoffs this year and maybe get a late 1st rounder in return. I'm not sure who a viable trade partner would be, though.
You could trade KG to Portland for Camby and Felton (both expiring) and maybe get a pick out of it, but Portland would probably be better off just hanging onto those two.
Chicago has nobody to trade us to match salaries for Ray.
I think we are pretty much stuck with this team until the season ends.
