This trade pushes each team further where they want to go.

Celtics: They pick up a center that they need, add valuable draft capital, and drop $17m to gog all the way under the tax to reset.

Magic: They need more offense, so they continue to trade defense for offense.

76ers: They pay 3 1sts to get off of the absolutely horrible Paul George contract(Maybe 1 less first to the nets would work as well but I think this is better.) They add some amazing depth pieces to contend immediately

Nets: They give up one bad contract for another, and pick up 2 1st for their troubles.
