In all honesty it's all still up in the air.
On one end of the spectrum, if the Hawks pull it together and Charlotte doesn't, we could be left with as little as a couple of late 1sts and a couple of late 2nds (if Charlotte doesn't make the playoffs within 3 years and Atlanta contends and is better than us for the next 4 years). Measly return for a young all star.
On the other, the Hawks blow up and those unprotected picks and swaps turn into 3 lottery picks and Charlotte's into a mid first rounder. That's franchise altering.
So basically it's a big gamble. As it stands right now, nothing is settled but I'm cautiously optimistic (unlike I was at the time of the trade).
