There are several teams that I think could work for Durant. the criteria are basically a contender with Durant and pieces for the Nets.
Picks (amount varies) and other lesser pieces like Curry could be involved
Boston - the Brown centered ideas
Miami - Bam to a 3rd team, Herro, picks - they can even add in Lowry and take back Irving
Toronto - Siakam, OG, Tren
Denver - Porter, Murray
Golden State - Wiggins to 3rd team, Kuminga, Wiseman
Memphis - Jackson, Bane, Brooks
Atlanta - Collins, Okongwu, Bogdan
New Orleans - Ingram, Jones, Hayes, Lewis, Murphy
Oklahoma City - Dort, Giddey, Bazley, Poku, Williams, Mann (and like 10 1st's)
Chicago - LaVine, Ball, White (they take back Harris)
and just for fun
Los Angeles - Davis, Westbrook for Durant, Irving
