What about a combination of Taj Gibson and someone like Butler/George?
If Fultz goes before our pick, offer something like the Brooklyn pick and Crowder for Butler or George, which is about the value they'll have at the draft.
Trade Bradley for bench pieces or future picks and sign Taj in free agency. That leaves you with:
PG: IT, Rozier
SG: Brown, Smart
SF: Butler/George, ?
PF: Gibson, Yabu
C: Horford, Zizic
I'd probably go that route, but I'm also not really enamored with anyone other than Fultz in this draft.
