The Twins have to make a decision if they are also-rans, building towards a team dominated by their prospects, or if they want to make a push further into the post-season for 2020. Salazar is a place-holder, be it in the bullpen or the rotation. They can spend lots of money, like they did in 2019, on pieces that may or may not play out. Of course, spending BIG MONEY doesn't ensure production.
They need a back-up catcher, make a decision on who's on first (or third), solidify the backup infielder, figure out the future outfield (i.e. Rosario gone and who plys there), add a REAL closer and another significant bullpen arm, plus a couple of solid callup guys for AAA ball. Plus, add 3 bonifide rotation arms, be they one-year winners or long-term assets. They can afford one "rookie" in the rotation and have Thorpe, Dobnak and Smeltzer as the current placeholders, plus whatever the decision is on Graterol (who I predict will start as a starter at AAA Rochester).
The Twins do have $70 million to send, That is a lot of money. They should spend it, because winning will only increase the value of the franchise!
