I’ve heard Beane say McDermott started trusting the front office more and more. This was probably 2020. I think after 2020 Beane started getting more control and influence because he earned it.
I honestly don’t know if they keep Beane after firing McDermott.
As for poorly coached, I definitely don’t agree with that. Overall throughout McDermott’s tenure they are one of the best coached teams in the league. The problem seems to come in crunch time. But a lot of times the players are in position to make plays they just can’t make the play.
