(4) Dallas Cowboys’ head coach Jason Garrett is seen here with assistant head coach and offensive coordinator Bill Callahan at the team’s training facility in Oxnard , California ,. Callahan is said to be slighted with Jerry Jones’ decision to hire Scott Linehan to become secondary adviser and offensive coordinator as part of the franchise’s already burgeoning coaching staff. Garrett , himself blindsided by the hire , is now said to watchful of what now appears to be a changing environment within the organization. Jerry Jones has issued a public statement standing behind his head coach , but states that the hire should be seen as nothing more than seeking to bring fresh input and set of eyes with the regard to the team’s offensive options.
