We don't know what will work out. But we are more than a year away from contending. Some of you from this post would have given up on the Twins position players in the late 90's that developed into a decent group by 2001.
I think you should trade Dozier and maybe Santana if you get a good offer including near MLB ready pitching. In the bullpen I am ready to give a great number of youngsters a chance. 2017 is going to be a lost season(hope not but that is the probable reality).
Only major pitching piece I might sign would be one of the 4 major closers available. You can flip them in July if you get a great offer and pin a bullpen on them since you will contend during their good period. Rest of this years pitching a going to get overpaid, avoid it.
Trading Dozier(and or Santana) for a major league ready pitching prospect or two is the way to go. Dozier needs to be traded now as his value will never be higher, and are you going to sign him for 4 big dollar years at age 32? But not for a group of A or A+ very good prospects who are 2 years away. I would not offer Gibson a contract as I feel he is not more than a 5 starter and Twins have too many of those.
Twins will have a crunch in the next 2 years of players eligible for the rule 5 draft and you need to see which ones will succeed. IF you do not this board 3 years from now will be on the fire the GM line after one of the players missed turns into being a star who was lost for $50,000.
Yes next year might be painful, but you also might get lucky. The position side of this team is not that bad and improving. It is the pitching you need to fix. Not all of the position players will succeed, but you have enough players already in AA or AAA to fill holes ans see if someone else can do the job(Palka, Walker, Gordon, Vielma, Granite, Garver, Murphy,Park).
For this to work Sano has to play 3rd for the next 2 years(unless Mauer retires or can be bought out to retire). So Plouffe is an extra and needs to be flipped or non-tendered. Between Plouffe and Gibson, you will have the money to sign a big closer, without changing payroll by that much and fixing the back end of the bullpen. Perkins could also be done and you could get even more salary relief there.(injury retirement).
