If the Knicks' staff likes Derrick Favors, they might give us #21 and filler for Derrick and #30. The Knicks are going to lose Taj Gibson and Nerlens Noel. Mitchell Robinson is coming off a broken foot. Derrick could take minutes at the 5. The Knicks have 2 picks at #19 and #21.
That might make some sense. That would put the Jazz in play for Murphy, Springer and Thor, maybe Duarte.
Knicks could then deal #30 and #32 to move back up to the mid-20s, or use one of those pick to acquire additional assets. That would be a good play for them.
If I were the Jazz, I think I'd make that proposal.
