Sure, the swap reaches beyond just this year, but the bulk of it affects '22. I don't think it was a chose A or B situation in regard to Correa and Donaldson.
The trade was sold as the Twins buying low on Sanchez and Urshela. To date, each has been even worse than their low points in NY. It's hard to say the Twins have gained much other than money off the books in '23, and quick math says there should be plenty of that with or without Donaldson.
The Twins have maybe broken even at C, though I'd note that Garver had a similarly rough start last year and still ended up posting pretty good numbers, and they've seemingly downgraded at 3B. It's hard to say the they've gained much other than money off the books next year (which there could/should be plenty of with or without Donaldson,) and that's assuming it's being spent wisely, if it's even spent at all.
