Really good take and I very much agree with the gist.
I would add that the roster wasn’t constructed well to support a pinch-hit heavy approach. The most relied upon hitters, Buxton, Correa, Lewis were the least reliable, and so the reserves spent most of their seasons as starters and then when the pinch hit situations occur, Rocco painted himself into a corner with Margot especially, but Martin and others that spent many innings out of position or just plain playing when they shouldn’t have.
What’s hard about all of this is knowing how the execution decisions are made.
So Baldelli kept going back to the same darn well, over and over, with worse hitters replacing bad hitters and the swirl continued.
How does the review/check happen to evaluate strategy/execution effectiveness during the season? Did no one see these decisions backfire over and over and raise their hand to question effectiveness?
