It sounds like Atlanta is about done with John Collins. His contract is big enough that they haven't been able to move him and get back the return they want. Jazz have shown interest since last summer, but reportedly wanted draft compensation included. I'd look at Atlanta as a potential destination for Hendricks or Jackson. It looks like they'll finish in the play-in range again. Atlanta has been playing Jalen Johnson, but he's still mostly a non-shooter.
The fact that the Jazz have shown interest in Collins this long might also suggest they're a potential Hendricks/Jackson destination. Maybe Sidy Cissoko can get in that discussion?
