I know Nimmo has been brought up as potential trade acquisition.  What about Dominic Smith?  He's left handed, had good offensive numbers in limited plate appearances last year and could fill a DH/1B need.

I honestly have no idea what to make of the Mets.

I think one thing to keep in mind is they are competing, so to some extent I 'd expect them to want ML pieces or near-ready ML pieces.

I have been reading that among other things they just are stuck with the lack of defensive versatility in CF with their offensive players. We are not a tremendous fit there, they'll want an immediate upgrade and I doubt Adam Engel is their cup 'o tea.

If there is a Betts sweepstakes, I expect mets to be in on it.

I can see the Mets landing JBJ since they really need a CF.  

I'm not really sure what their plans are though.
