At lot we do not know. First what is the new CBA, but you may have to make decisions before that. If you are sure there is going to be a floor, you have to resign Buxton, because otherwise you are not getting there.
Keeping Gordon around is a possibility to backup center along with other positions. 3 players who have no future here are Cave, Simmons and the Turtle. Several of the lower rung pitchers can be jettisoned also. Along with about 3 players on the 60 day DL list.
FO has to do a better job on talent evaluation. Under Terry Ryan you rarely saw a released player have a big impact (David Ortiz, but not many others). This FO has several relief pitchers and maybe 1 starter (Gil) who could carve out decent major league careers, while the Twins bullpen suffers.
Donaldson is a issue, but I would trade him (as a sunk cost) for whatever I could get (salary relief and lottery tickets are most likely) to open up positions for the next wave. Most of them will not be here until next spring or summer, but we need to move forward. This also includes buying 1 front line starter to stabilize the rotation and also if a floor to help get us there.
Baldelli needs to play the younger players, and if he will not (except when we are facing playoff contenders), we need to release those players so he cannot use them.
Next year could be bad, but it is the only way forward to find out what we have.
