It might be harder to draft better players with the 14th pick vs the 20th, but if staying "somewhat competitive" means extending Betts, one could view that as helping us be more competitive in 2021 ans beyond.
I do see the logic in thinking let's go total reset for 2020, and deal away every player not viewed as being helpful in 2021, but the bigger decision is do you expand that thinking to 2022 as well?
Guys like ERod, Workman and Barnes could all be very key pieces to returning to glory in 2021, but it sort of forces a 1 year window and not a longer term plan- not that we can't extend or resign most or all of those three.
My guess is JBJ and all the FAs go, even Holt. We may look to trade JD (assuming he does not opt out). Trading Price, Sale and/or Eovaldi when their stock is low doesn't seems like a good idea, despite opening up some partial future spending space. I could see trading one of them at the deadline.
