Well, it's fun to talk about something that is nearly a rumor.
If C's can get him for any combo of Lee, Amir, C's #1, Dallas #1 -- I am on board. No Brooklyn picks!
That said, I don't see the benefit to Atlanta unless they know they will lose Horford (which I doubt they know) for nothing.
Interesting that the Hawks are on;y 3.5 games out of the ninth spot, so they could easily slide into the lottery. With the Dallas pick, they could hope for 2 lottery picks. But still, they're not getting into the top 10. Low value for Horford I think.
