I do think you have to give them props for Correa as opposed to Donaldson, that's a legit upgrade.
Other than that, they have the same problem as last year - a patchwork pitching staff. But...the Twins have an obnoxious habit of making the playoffs with a patchwork pitching staff. 2019, 100 win team, starting rotation of Berrios, Martin Perez (ERA 5), Jake Odorizzi, Kyle Gibson, and Michael Pineda? Come on, that rotation shouldn't win 90 I don't care how many home runs your team hits.
A real weakness on them though? I wonder if they've set themselves up really poorly with Gary Sanchez at catcher having to work with those pitchers. Combination of bad defense and bad overall catching might not be what that patchwork pitching staff needs to hold together.
