You cannot put what happened under Patricia in its own separate incident. Time is not broken up into distinct moments. It is a continuous flow. Mac went into last season still with McDaniels coaching fresh in his mind. Then he gets to 2022 with Patricia and O'Brien and it all starts to fall apart. Go back to last year and every analyst that looked at Patricia's schemes called them trash, simplistic, and incompetent.
That call Mac made to his college coaches was pure desperation. What Belichick did in hiring Patricia and O'Brien was UNPRECEDENTED. Coaches have trained on both sides of the ball, sure. But NEVER straight up as the highest position. Typically they would START as an assistant position coach, not the coordinator level.
Then there was this year which saw even more weapons, more blockers leave, along with the only receiver Mac could consistently trust. Right now, we have to move on from Mac because he's broken. But the guy responsible for breaking him is still in the building.
