You're much more likely to use the 4th pick for George than Turner, who would be close to untouchable for them.
But I do think that we should seriously consider trading the pick if we don't get a shot at Fultz. I want no part of Ball, and I don't think Jackson is really the direction we should be going in. I could be talked into Tatum, but I'd price a George or Butler trade first.
Would people do George for Crowder, Rozier, and the 4th pick, assuming both Fultz and Tatum are off the board? Then you could trade Bradley for someone like Faried, which would leave you with the following lineup:
PG: IT, Smart
SG: Brown, ? (maybe Green resigned at the minimum)
SF: George, Yabu
PF: Faried, KO (resigned)
C: Horford, Zizic
