I agree with most of this, though I'm concerned about a couple of things:
1. Can Miranda play a useful position or is he going to logjam Sano/Arraez/Larnach/Kirilloff even more? And if he can play third base, how confident are the Twins in moving away from Donaldson? This team can only handle so many corner guys and they already have too many of them.
2. I love the look of the pitching pipeline... on paper, which I'm sure you agree with.... but I have yet to see any execution of transitioning good prospects into good MLB players, which makes me wary of how much progress we'll see and how quickly we'll see it.
Which makes me wonder if the team's best option this offseason might be to trade 1-3 of Donaldson, Kepler, and Garver and stack that pitching pipeline even more, preferably returning at least one decent MLB player under control for 1-3 seasons. It's dangerous to loot the offense too extensively to bring back pitching returns but also, I don't see much choice in the matter if this team wants to start competing in April of 2022.
What makes me optimistic is that unlike most terrible baseball teams, this front office has a lot of talent on-hand, which gives them a bunch of options to improve if they pull the right levers.
