What about a sign-and-trade for Milsap? Atlanta clearly isn't keeping him, so they'd be willing to do a sign-and-trade with us, as well as Milsap wanting to come here I would guess.
I guess it would depend on how much he was demanding, but I do like the look of a IT, Brown, Hayward, Milsap, and Horford starting lineup with Rozier, Smart, Tatum, Zizic, and others backing them up.
