Falvey and Levine have basically been trying to buy time until the prospects arrive, and they have slowly been trickling in.
Archer and Bundy were supposed to placeholders, but wound up being counted on at MLB due to injuries and slow development. Same with Happ and Shoemaker in '21.
Colome' and Pagan were relied on for too long, with Pagan publicly being outed as resistant to coaching. Perhaps Colome' was also.
I believe (and several TD posters disagree with me) that the lost season of 2020 hindered a lot of players development. Pitchers were throwing with no coaching (perhaps leading to injuries in '21 & '22, it can't be proven either way) and many position players were missing valuable hitting and fielding coaching. Also, these players were not getting professional baseball strength, conditioning and stretching coaching/supervision. All a formula for failure.
To the eye test (mine anyway) injuries, especially to young players, seem to be up over the last 2 full seasons at all levels. And many of these players would have advanced at least 3 levels over the '20 & '21 Milb & MLB seasons, that's a lot of missed high-level competition. And don't tell me that all of baseball dealt with the pandemic and missed seasons, I know that. It just appears to me that the Twins players being counted on for future development were in the stages of development and at the ages where coaching mattered and they were unable to get it.
All this and what team could withstand losing their starting C, 1B, 2B, LF, CF, RF, replacement 1B, replacement RF/LF, 3 starting pitchers (actuaully 6, but Archer shouldn't have been here that long Maeda probably wasn't counted on to contribute much, and Mahle was acquired at the deadline), and various relievers and role players throughout the season?
