I don't think he will be back, but I'd gladly take it.
The Math in his head has to be...can he get more than 14M on the FA market and I think he can. He'll have ~25 HRs, he's not had a great year, but 14M? 4M is GTD, I'd be happy with him coming back. I agree, year 2, plus he's hit into poor luck, I'd gladly see Hoskins back.
Chourio/Yellich/Contreras/Hoskins as your 2-6? I think that's up to 100 HRs right there.
Ortiz, Turang, hopefully Black and Frelick, they'll be able to get on base as well or... a little better. I still don't' know what Mitchell is other than talented, but streaky.
I looked up the FA rankings, they have Adames as the #20 FA or so. I think he's top 4-5 behind Soto, Burnes maybe Bregman and Cole, but we'll see.
Just need that one year fill in at 2B/3B or...SS, though that's more expensive and less important with Ortiz and Turang.
