I think if the Jazz only give up Mitchell, we end up with one of two combinations:
#1 The Knicks unprotected picks in 23, 25, and 27 plus 2 protected picks plus Evan Fournier, Obi Toppin, & Quentin Grimes.
#2 The Knicks unprotected picks in 23, 25, and 27 plus 3 protected picks plus Evan Fournier, Obi Toppin, & Immanuel Quickley.
Of course I would love a swap or two, but in the end this would be a reasonable compromise for both teams. Players plus 5 firsts with 3 of them unprotected if they include Grimes or throw in an extra (6th) protected pick if we get Quickley instead.
