All make sense for the right value, as do several BP arms. I want impact players as cheaply as possible because the Braves have plenty of "good not great" players.
Wheeler will probably be the cheapest guy capable of making a real impact on the 2019 season, and I'm not sure I want to see the Braves tie up even more resources into controlling a pitcher like Boyd or Stroman for more than the rest of this season.
Wheeler and Smith for good value would be a pretty good deadline.
Folty turning back into a #2/3 and Gaus turning back into a #3/4 while getting Smith for 3 FV 40s would be the ideal, imo.
