Trade works if the Wizards Draft AJ Dybansta and sign him to a contract, then use that contract as salary filling for Giannis but not before Draft.
So you keep young core pieces, while adding Giannis, and create a Big 3 in Washington with Trae, Giannis, and Anthony Davis.
Then we sign LeBron to the Red,White and Blues. And have a Big 4, with young core pieces still around.
Trae, Bub, Bron, Giannis, Davis. Thats a team that takes #1 in the East next year.
