Before we blame Carr

I will go two steps further and say that Pete doesn't really know this system.

He tries to do the player swaps thing, but they make him more predictable. He calls bombs down the sideline on third and short, where the sideline benefits the defender. He runs up the middle on second and long. He has no rhythm or feel for the game, and not having the most cerebral on-field QB of all time to cover for his predictability is exposing him.
He's a former mid-level executive who's now in charge of a huge corporation his once, more intelligent, maverick yet adaptable boss created but once he's retired or moved on, he doesn't know, recognize, or understand the rhetoric, feel, multiple nuances of the extremely complex algorithms his boss used to be so successful and so he brings in another CFO thats not as cerebral or instinctive as previous one but believes if he follows enough of his old boss tactics and strategies in business, eventually it'll click for him.
