Cross-posted--comment below. In particular, would you add the 2013 TWolves pick to entice the Hawks? I'd go ahead and do so, mobile PF/Cs who can shoot like Horford are so rare. He and Len would be an incredible 1-2 in the post. Best of all, he can run. Hornacek would be so very giddy. Though he's quite a bit older than the younger core of Bledsoe-Goodwin-Len, I could see Horford holding up well here. He would certainly enjoy moving over and letting Len deal with the center spot.
