Why the Heat do this:

DeAndre Hunter and Clint Capela could be extremely solid long term role players next to Herro and Bam

Why the Hawks do this:

As the title says, Jimmy and Trae. Instantly the number one duo in the East, with a supporting cast of Daniels, Okongwu, Bogdanovic, etc. This group could make a real run in the playoffs and maybe even win it.
