The problem is that they need to get rid of short-term money. Right now they're at $165M for the next season.
Getting rid of Brogdon and Grant puts them at 113M.
Adding just Keldon and Zollins would be 36M, so they're back at 149M and well over the cap, even without Graham.
I don't want Brogdon, tbh. Always injured and supposedly a bad teammate.
I'd reduce the Spurs bit to just Keldon+Chicago+seconds as outgoing and DJ as incoming.
Then we get rid of Zollins somewhere else.
But then that looks like a steal for DJ.
