I know this is a small possibility but if KD did reunite with Golden State this is what I think the trade would look like.

Nets get a top 2-way wing in the league who is still only 27, breakout guard who still 23, former 2nd overall pick who has struggled with injuries but looks to be back now, and one 1st and one pick swap (possibly get another 1st but there getting such a haul in players that I see them only get 1 and a swap)

Warriors bring back the superstar they won two championships with.
