There were several thrown out there, most of which they thought the other team would turn down because of Mitchell's deficiencies (height, defense, etc). They did mention Orlando could be a destination that makes sense but didn't mention specific names. The one interesting proposal:

SAC gets: Donovan Mitchell
UTA gets: Davion Mitchell & 2022 #4

Most draft analysts have called this a 4-5 player draft. This would give the Jazz a chance to land one of those premiere guys (likely Ivey or Sharpe) while adding an established premiere perimeter defender to the backcourt. Sacramento wants to win now, so they thought this is something the Kings would like to pursue, though obviously these are just the core pieces and the salary matching would have to be worked out.
