This is fine and a neat narrative but most of the team's turnaround can be explained by regression to the mean. We literally have no idea what level of accountability was going on behind the scenes under Montoyo and the comparison to that of Schneider. This was always projected to be a good team so it's not surprising to see them eventually play up to what they were expected to do. I really don't think Montoyo, as much as I didn't love him as a tactical manager, was the reason the team was underperforming so much. He also had to deal with key injuries to the rotation, Kikuchi actually being a starter, and worse bullpen help/rotation depth prior to the deadline, which Schneider obviously benefited from. It's easy to say his firing was the catalyst and Schneider really lit a fire under them, but most likely this is all just random noise which the new manager gets to soak in the narrative from.
