Jason Garrett was given a new deal earlier this year. The hesitation around a new Garrett deal was to wait until Garrett lead the Cowboys out of the first round. Garrett told the Dallas Morning News when asked about the contract during the season that he was never worried about a new deal.
I believe Garrett when he says he was never worried. Jerry Jones larger than life personality can potentially clash with other coaches style. Garrett plays the role of punching bag very well. I think Jerry knows very well this positive trait of Garrett and that more than enough reason to keep him around.
