It has always started with the players, they're first in the line of fire. The Rocco/FO chatter has picked up as the on field product has underwhelmed over time.
I'm not asking Rocco to throw anybody under the bus. You can provide reasoning without doing that. You're right Rocco or Falvey are under no obligation to discuss decision making, but you're going to lose the benefit of the doubt faster if you're leaving decision making open to interpretation. As far as playing things close to the vest is concerned, we watched opposing teams goad the Twins into removing better hitters midway through numerous games simply by bringing in a LHP. It was possibly the most obvious move in baseball. I don't think the Twins are protecting some master strategy by not giving a reason for in game decision making.
We'll never have all the info. That's an impossible bar to clear. IMO you don't need every tidbit to make a solid case.
They've missed the postseason 3 of the last 4 years in what is supposed to be a contention window. The one year they made it, they borderline backed their way in. I have no clue what projection systems they did or did not beat/match, and to be honest, I don't give a f*** about preseason win expectations. They mean nothing.
I'd rather see this FO go than Rocco if I only was allowed to choose one. Ownership is their own problem, but they don't meddle in the baseball ops department.
