I think if you get Schwarber, you need to play him at 1B.
I personally would be thrilled with that prospect but I don't think there is any way they trade Freeman now, no matter the return.
As an example of my thinking: Inciarte and Cabrera to Chicago for Schwarber. Freeman and Kemp (Braves pay most of Kemp's salary and Kemp is DH) to Houston for Bregman, Cameron, Tucker and Fisher. Teheran and Mallex to Colorado for Dahl, McMahon and Nunez. Markakis and Newcomb to the Yankees for McCann and Frazier. Whalen to the Twins for Santana and Hughes. Sign Morton.
2B Albies (Peterson to start 2017)
SS Swanson
3B Bregman
1B Schwarber
RF Frazier (sign Beltran for 2017, 2018)
CF Dahl (Acuna future possible)
LF Fisher (Cameron, Peterson, Riley future possible)
C McCann/Flowers/Recker (Carry three catchers with McCann getting time at 1B)
Rotation: Santana, Folty, Wisler, Hughes, Morton (long term Weigle, Allard, Fried, Touissaint, Soroka,etc. add in.)
Pen: Johnson, Viz, Withrow, Krol, Simmons, Ramirez, Bradley/Rodriguez
Won't Happen. But not impossible.
