How about the Cavs as the 3rd team taking on Wiggins and sign and trading Sexton to Brooklyn. I think that would require Harris going to GS also so Brooklyn can get below the apron (and sending 1 less 1st to take on Harris).
So
Golden State - Durant, Harris
Cleveland - Wiggins
Brooklyn - Sexton, Kuminga, Moody, Wiseman, 2 GS 1st's
I think that would be a pretty interesting trade for all 3 teams and does make some deal of basketball sense. GS would obviously be the heavy favorites to repeat (even taking Durant out of it, imagine Harris in the Porter role on that team). I also really like that move for the Cavs. Wiggins just makes a ton of sense as the wing the Cavs are missing. And that starting 5 would be young and nasty with Garland, LeVert, Wiggins, Mobley, and Allen and still having some vets like Rubio and Love on the bench and solid youngish depth in Markkanen, Okoro, Osman, and Wade rounding out the rotation. Brooklyn gets a #1 scorer which they will need once they finally off load Irving and I do think Sexton and Simmons could work well together as they integrate the 3 recent lottery picks and a couple future 1st's. They get out of the tax as well giving them a reset. Need to find a place for Irving, but that does in theory work long term for the Nets with Sexton, Simmons, Moody, Kuminga, Wiseman having the talent to really develop into a legit starting unit a couple of seasons (and they have Sexton and Simmons long term in that scenario).
These sorts of trades are always so complicated to make work, but I think this one actually gets something that the 3 teams could use.
