C's would need at least a protected 1st back and I'd expect Al is moved as I don't see the fit with Gobert. For who Al is moved for, I have no idea.
Jazz add youth and clear up the Mitchell and Gobert rift. Even if they added a 1st I'd see them jumping at this.
C's would also have to make good use of their top two TPEs as their depth is shattered. So far the market is moving quickly BS would have to act swiftly.
