I think we do know that it isn't Brady driving the bus. Bowles made it clear when he became head coach that he's the boss and that they are going to stick with the run. True to his word, they continue to run on almost all 1st downs. As for Leftwhich, I don't think he appreciated looking like a cukk on national TV when Brady overruled his play calling a year ago.
Lastly, for Brady, I think he's just going through the motion. We saw it in 2019 when the team gave him utter garbage with aging players, bad drafting, and bad FA signings. We are seeing it again in 2022 with the team sticking to their stupid play callings, starting Brate over Otton (previously sticking with Goedeke too), not going for it at Cleveland's 37 line (at least go for the 50% chance of making a field goal), Evans stepping out for a 29 yard gain instead of trying to get a TD, not using time out to end the game with a field goal for the win. I can't blame Brady for not really being into it. The coaches are so moronic and it's effecting the whole team, Brady, Evans, etc.
