Core of the trade
Simmons + Matisse + Draft Capital <-> Harden
Westbrook + Harris -> Knicks
Knicks get two stars in Harris and Westbrook and keep their draft capital and young players.
Sixers go all in on Harden to complement Embiid. Also take on Gordon's bad contract and Covington.
Rockets get several young pieces and nice contracts in Ben, Matisse, Josh, DSJ, Portis, as well as several 1rp.
