I saw it differently.
He tried to keep up with the times by hiring Waldron to bring in a McVay style offense. Waldron just didn't do a good enough job of implementing this offense, consistently.
He tried to keep up with the times by allowing Hurtt to bring in a Fangio style defense. Hurtt failed miserably at installing and implementing this Fangio defense.
So it wasn't for lack for trying. He knew he had to adapt to the modern NFL.
His issue wasn't control over coordinators. It was not hiring competent coordinators in the first place.
His
"You be You" approach applied not only to players, but coaches as well.
He should have 1) tried to make it work with what he knew best OR 2) hired the best in the business to get it done.
He didn't do either.
