And Peterman might get a start this season and go on to have a more successful career than Mahomes. You don't know what the future holds!!!
But as of 11:09 PM Central Time, Peterman is a bum, Shanahan, McVay, Reid are the best offensive minds in the game and nothing about Brady's body of work to date suggests he will be considered in the same tier as the guys above.
All of those guys got head coaching positions based on their prowess as innovative offense coordinators.
