Heat get a shooter with size who will fit perfectly between Bam and Jimmy.
The Kings get another draft pick to help... whatever it is they're doing. Robinson gets a chance to rebuild his value in the starting lineup with Murray sliding to the 4.
Barnes no longer has the trade value he had a couple of years ago, but moving Robinson's contract will take at least a 1st.
This is likely more realistic for the Heat than going after Markkanen.
