Can't agree with you on the rookie thing. The current Twins are not a playoff team. Cleveland just proved that. And a team doesn't "improve" by keeping average players in the lineup when it has rookies that may be better. But the only way you can prove a rookie can do a better than average job, is to play them. A lot. And give them all the chances in the world to play at the position they have been trained for at the level of competition you need them to play at. If you have to play them at a new position, then its only fair to cut them some slack while they adapt instead of immediately condemning their performance and ruling them a disaster.
I've been preaching all year that this season is for the Twins to kick the tires on their prospects if they want to be a playoff team next season. Witness the negative effect the absence of Sano and Donaldson has had. None. Yet the 2022 team is better than the 2021 team because getting rid of those two made room for Arraez and the rookies. Yeah, the rookies will make mistakes, but that's how rookies learn. And if they get enough playing time this year, they won't be rookies next season.
