DH is only open if Masa and Ref are gone. And even then, if we don't trade one of Abreu/Duran, we will need the DH spot for the outfield jam. Our 1B needs to be playing a lot of games.
2B is almost certainly going to Story/Mayer.
3B will be interesting if Bregman opts out. I can't shake the feeling he isn't however. That injury and late season slump will hurt him. Ideal world is he stays with us for the next two years and we miss out on the bad part of any potential contract coming his way into his latter years.
C - would not be a surprise if it's Wong as back up again.
Definitely need some bullpen help and a #2 (wouldn't be surprised to see a #3 come in though).
We've got stuff to do, but I don't think we'll be getting anywhere near as much as some of the lists I've seen bandied about, including yours. I think we'll see a few trades this summer, however.
