Burke not Brunson?
Brunson if you get a better PG incoming, who is already inked for another year?
(Because, Dragic fits that description. And Lowry might as well, depending on how you negotiate.)
(EDITED - Never mind on Lowry. Looking closer, he can't be extended and has to be a FA in 2021. That takes any swap of Brunson for Lowry off the table imo. But Dragic would have to be traded with his option exercised, so if you think Brunson gets too tricky/expensive to keep in 2022, and is only here until then, trading him for Dragic means you still have a backup PG until 2022, but a bigger and better one presumably.)
