I would switch with the Cavs, so much talent and still pretty young. I really wanted Herro that draft but fell one spot too late so would be cool to have him now.
It would have to be the Hawks (other than the Heat) solely because of Fland. It takes an elite point guard to win a ship in FBB, and Fland is on track to potentially be the best point guard in the league. That's the ultimate starting point, it's easy to fill in the pieces from there once you have that elite point guard in place.
