It didn't work out but look at it
Outside the Kiriloff left field hole to start the season that is exactly what the Twins had. A projected defensive powerhouse left sided infield with masters in those positions. Same with centrefield and right field. Sano who is pretty good at first, Garver and Jeffers as good catchers. I'm sure you are talking about Astudillo who is lovely to have on the bench to cover injuries but shouldn't be starting in the field or relied on to hit. Arraez is serviceable alongside Polanco defensively. Then Cave who fits the role of the 4th outfielder on a team with a strong DH- There for cheapness, defense and flexibility but again isn't an everyday starter.
Then in the bullpen on paper you have 3 closers- Rogers and Robles projected to return to 2019 form, and then Colome who WAS a shutdown guy last season, looked a bargain at half the 2020 price and should have suited the defensive infield. Building the roster you are balancing cost with upside and expected performance. Colome even with some regression built in looked good, you can't predict his cutter stopping working based on available data. High leverage situations aren't always the 9th so its good to have flexibility rather than one superstar you are scared to waste or gas.
Coming into spring the Twins had Speed (Buxton, Cave Polanco), Defense (Donaldson, Simmons, Buxton), Reliable hitting/Patient hitting (Cruz, Donaldson) plus strikeout guys like Robles in the bullpen.
In terms of the players called up for depth Refsynder, Gordon, Larnach have all done well. Bullpen depth perhaps not but a lot of the guys were projects that maybe didn't get the time before being pressed into service. Even with starters there were 7/8 guys set to go opening day. I'm not sure with the budget *And Knowledge* available that there could have been much else done on roster construction. My view is early bad form, surprises and injuries got the Twins behind where the pressure mounted and the fundamentals fell apart. E.g. the infield Errors have been too high but I'm not sure how that could be predicted preseason.
