Who you trust to fix the defense?
The Kiffin/Marinelli hire has been a failure.
Garrett has no overall defense philosophy, and never did when he was hired as head coach.
By default, there was no one to question or confront Jerry on the Kiffin/Marinelli hire.
Marinell's "success" prior to Dallas was based on being a coordinator for Lovie Smith in Chicago and a D-line coach for Tony Dungy in Tampa.
Both Lovie and Tony know defense -- something Garrett has no clue about.
And when Marinelli was the head person in Detroit running the defense, he was never good.
Combined with Jerry's very poor drafting for impact players on defense with premium picks (1st round - Anthony Spencer, Mike Jenkins, Clariborne, Jones) for over a decade -- not one defense lineman drafted in the 1st round since 2005 & his poor free agent signings on defense (Carr, Hardy, Thornton, etc.) have done nothing for the franchise.
Jerry and Marinelli as your GM and coach of the defense ain't going work.
A lack of defensive talent and defensive innovation remains.
In the playoffs, elite QB's or elite D's are the key.
At least, the franchise has something to work with with Prescott.
