I'd still trade Brown and Irving and picks. I think a third team with a young player and expiring would need to to help. don't think NO wants Irving, but would love Brown. I just think adding AD and taking away Just either Brown or Tatum doesn't help. You're adding a 25+ scorer, need to free up the ball a bit more.
AD would give us a better inside out side game and teamed up with Horford, the paint would be well guarded. Move Hayward to the 2 spot and Tatum to the 3. Gives them both more touches, gives Hayward more opportunity to run the offense.
