No, he's not worth both Brooklyn picks AND Bradley. And Bradley is the real prize for them anyways due to being about as perfect of a fit for them as possible, let alone the defensive pressure that he'd put on the Irvings, Pauls, and Westbrooks of the world in order for Curry to rest on D.
However, I'd probably do something like Bradley, JJ, and the 2018 Brooklyn pick for him, which is about the least it would take to get him.
