Firing Avila is performative. It's also a way for the parking lot king to deflect his role in this disastrous rebuild. They didn't do anything aside from tanking and drafting high. And drafting by nature is not a sure thing. Their player development team was lead by a losing dinosaur who was only removed in late 2021.
The owner froze spending and left Avila to his own devices to find efficiencies outside of the draft. Instead, in year 5(or 7), we are relying on the Castro brothers, Eric Haase, and other sub replacement level players to fill out a roster.
It's somebody's fault that every hitter is broken. I don't know who to blame specifically. But in year 5(or7), I was hopeful that the major league product would be better. And with their track record of developing and promoting players, do they have much credibility that any of these prospects will succeed over the long term?
