Devers is the player to build around, IMO.
Keep Bogey and Sale, since we are not likely to get much for Sale, and Bogey only has prime years left on his deal.
We aren't looking at a 5 year rebuild. No way.
We should be able to turn this around by 2021 or 2022, especially if we go over the luxury tax line, next year.
If anyone should be traded, it should be players that become FAs after this year or next. Those players are:
After 2020:
JBJ
Pillar
Workman
After 2021:
ERod (if we can't extend him)
Barnes
Hembree
I'd even explore trading JD. He may not be much help on his last year of his deal in 2022.
One could argue trading them for the best we can get, even if the return is not equal. Just get controllable- low cost players in return and strengthen the bottom of our 40 man roster and the farm.
