A ton of mocks have Irving going #1 and Kanter falling to #4. So why would Cleveland essentially want to swap Irving for Knight?
Because if Jazz for some reasons selects Kanter, then Cavs cannot select the next BPA (i.e., Knight).
Then Cavs would have to look at someone else at #4 who will be at least 1-tier below the Irving-Williams-Kanter-Knight quartet.
It's basically a game of chicken between Jazz & Cavs, as Cavs don't know what we'll do.
