That is the minimum courteous press release when making a change in upper management.
Since I don't think any of us has much of an idea how Falvey and Levine shared the decision making duties, or (equivalently) what Falvey delegated to Levine, or what their working relationship was like, we're mostly just speculating. After several years, was Falvey genuinely disappointed with the independent decisions Levine made? Were the major decisions all joint, and they jointly concluded the process wasn't working? Did Falvey need a fall guy in order to preserve his own job? (A little less pointedly, was he instructed by ownership that "something will have to change" given the poor 2024 outcome, and this was the change he genuinely opted for?) Considering the way that they were thought of together in 2016 going forward, these latter options are a sad outcome but not every working relationship lasts forever.
Levine's seemingly kept his mouth shut in the meantime. Has anyone here listened to his podcasts, and picked up traces of anything regarding his time with the Twins? He could make waves, but probably believes that would kill any remaining chances in the baseball world.
And so we just sit. And speculate.
