I suggest a trade. ALex Burks and Tre Burke for Jeff Teague. Obviously I would try someone less than Burks first, but I don't think Atlanta goes for it without Burks.
Teague has two years left on his deal which is perfect to make a move this year and next, and hope that Exum gets back next year and progresses. The emergence of Hood has made Burks expendable, even if I like his game.
