I can't take away fifty plus HR's out of the line-up, both relatively patient hitters, and supplement it with Jason Heyward, and a pitcher that pitches every 5th day.
Heyward is good, don't get me wrong, but I can still get him while strengthening up the rotation and not trading away extremely valuable pieces.
Now, Soler I would be willing to deal, especially if I had Heyward, and I would say that Soler could headline a package or be a part of a three team deal to get some cost controlled pitching in here.
If they were willing to go after Shields, then I see no reason that they won't go after Lackey on a similar AAV, but not for four years.
