Sorry, just doesn’t work that way. Even though Brady didn’t have a career year, it’s not only touchdowns and yards that help win games. Putting the line in the right position, not taking a sack, getting rid of the ball...all help field position and make the opposing team drive the full field. Not throwing interceptions doesn’t give the opposing team a short field and put pressure on the defence. It’s not as simple as saying name one game that would have made a difference with a different QB. The QB has a significant effect on all games.
