Well, politically, Ntilikina is not from KY, not a client of Rose's, and in Thibs' doghouse.
Rivers is the son of NBA royalty, belongs in a TV sitcom, and is one of the most articulate spokespeople a team could hope to have.
Knox is a young, relatively raw project.
The trick with all three is money matches. Generally speaking, NY is far under the cap and their likely trade partners will be looking for relief. The problem of course is that they'll want to unload an albatross for our spare part(s). So that gets tricky.
I have proposed Rivers and Knox for Culver and Layman. This simply flattening out the roster a bit more. Layman is capable of being a highly energized bench asset at the three and Culver was known as a shooter in college who might regain that talent yet again. AND Culver isn't yet another PG candidate instead adding depth at the swing positions. Obviously not the sexiest trade but a doable one all things considered.
Frankie, the obvious sitting duck is also the best paid of the trio and as such harder to trade given his inactivity. The forum wept rivers of crocodile tears when DSJ was sitting on the bench yet Thibs' staff has done its damnedest to bury Frankie alive and not a whimper.
