Again, there are two questions here... the macro question, which is why is this ballclub still a projected 70-75 win ball club after year five of the rebuild. And on that score, Al Avila is terrible and deserved to be fired.
And then there's the micro question of why a projected 70-75 win team has a lineup that is playing like a 50-55 win team. And on that score, as was the case last year, players have track records and it's reasonable to expect them to meet expectations.
This whole debate kinda minimizes the contributions of the player to the success and failures of the team. And more than anything else, that's why they are where they are in the micro... not Al or AJ, the players.
