I agree with all of this. I almost wonder if the early success, especially 2019, was harmful in the long term to the overall plan. That's not to say that success is bad, but perhaps it altered perceptions and expectations unrealistically. Particularly in the fanbase. That's not an excuse or letting them off the hook though. Adjustments can be made and plans can be altered to fit how things unfold, especially at the big league level. Expectations and perceptions should change over time.
I think strides have been made in many areas, but I'm not sure that I'm convinced that there's light at the end of the tunnel yet. I'm patient with these types of things, I realize that they take time, but I was hoping/expecting to see a bit more by now, especially regarding the pitching. That's ultimately what has always held this team back.
