Exactly. Judging by what Detroit did before the draft (traded away their SF/PF, Jerami Grant) and what they did immediately after the Kings picked Murray at #4 (rumored to be frantically trying to piece together a trade for Ivey, before making their pick), I think there is a good chance that Detroit was looking to trade up to #4 to take Murray, not Ivey.
If the Kings traded out of #4 for "more assets", we would had missed out on our targeted player, Keegan Murray.
