How about this massive crazy and totally unrealistic, yet realistic trade (i.e. the components seem like reasonable value but it would never happen)
IN
Boston - Cousins, Hibbert
New York - Lee, Zeller, Kelly (filler), BKN 2016 1st, DAL 2016 1st
Sacramento - Russell, Randle
LA - Anthony, Bradley
OUT
Boston - Lee, Zeller, Bradley, BKN 2016 1st, DAL 2016 1st
New York - Anthony
Sacramento - Cousins
LA - Russell, Randle, Kelly, Hibbert
So Boston picks up a defensive center and a monster PF. Gives up its most valuable asset (BKN pick), another 1st, and Bradley.
New York goes full on rebuilding by trading Anthony. Picks up the BKN 1st to pair with its own pick which will be a better pick, plus the Dallas 1st for some more depth. Clear rebuilding and build around Porzingis type trade.
LA gives up its two young pieces, but picks up a star to bridge the gap in the post-Kobe era. Bradley is a nice solid compliment to Clarkson and Melo going forward. LA likely loses its own pick in this trade, but has a shot at the playoffs (they surprisingly aren't that far back as the west hasn't been that good except for the two teams at the top).
Sacto gets out of the Cousins business and picks up two recent high level prospects in the process to pair with WCS.
In a vacuum I think this trade is reasonable for all four teams, but as I said it will never happen.
