In regard to the Sale trade, it could be that Dombrowski was willing to listen about trading Devers, but just not in conjunction with Moncada and Kopech. I think that Moncada and Kopech were already decided upon, and Hahn asked for Devers as well, to which Dombrowski said no. That's my understanding based on what I've read. So, I don't think it was a matter of Devers being 'untouchable'.
I have heard that Swihart has become untouchable, though, along with JBJ.
And as far as being concerned about the future state of our team, that does not detract one bit from the ability to enjoy this year's team. It's not an either or situation.
