I'm not high on keeping Hill and/or Blair but reasons that makes them not worth being extended are also reasons that limit their trade value.

Teams won't give you a lot for Blair and/or Hill, they aren't great trade assets for tons of reasons (limited size, limited upside, Hill only locked one year on a cheap contract, Blair knees...). Packaging Hill and/or Blair with RJ won't be enough to offset RJ's bad contract.
I think Hill will get a lot of interest from teams his contract is cheap and he is young and has name recognition with potential talent. If not then do a package deal with Tony and RJ that would allow us to move him. I know alot of people will say NO but looking at the last eight teams playing right now only Chicago has a star PG...
