There's depth and then there is a logjam. Wouldn't be surprised to see Puig moved if it brings back a quality arm, which is sorely needed since pitching is Kershaw and Greinke followed by a bunch of uncertainty.
There are still too many outfielders considering Guerrero is best suited for a corner spot, he has the bat to be everyday major leaguer but his infield glove is atrocious.
Ethier is proving himself valuable and might be the best time to unload him, Crawford is always injured... always. Van Slyke has earned a chance to start.

I'm sure the FO is exploring every option. Doubt moving Puig is the first option, but if you want a big arm it won't be cheap.
