I prefer to look at each season individually, so that's a major part of our disagreement.
As for the 4 year time period, the fact that the 2021 team almost made it to the World Series seems to counter the idea that there was a steady decline.
As for the general point that the farm is a big factor in success over the long haul, I certainly agree with that. I was not unhappy when they replaced DD with Bloom.
