Yeah, but the Hawks wouldn't. I'd try this . . .
To Hawks: Gordon, Bacon
To Magic: DeRozan, Walker IV, Snell
To Spurs: Collins, Fournier, Ennis III
Works as of February 23rd, when both Ennis III and Bacon become eligible.
Then immediately reroute Fournier for either draft capital or an inexpensive, controllable young player.
I haven't done a deep dive in terms of the future cap sheet, but it feels like Walker IV is going to get squeezed. It's difficult to determine his worth (terrible metrics, but still an intriguing talent), but if it's something like $10-12M, that'd be a steep investment when they've already paid Murray and White and seem well on their way to doing so with Johnson and Vassell.
You don't invest in five non stars (maybe Johnson changes that, but they can't count on it) who play similar positions, nor lose assets for nothing. You get out in front of it.
