The fact that the Dallas Cowboys are looking for a new offensive coordinator is a very big deal.
Throughout his tenure Jason Garrett has rarely made a move of this size. When it has come to moving on from coordinators, whether offensive or defensive, he and the Cowboys have typically phased them out as opposed to outright firing them. Just ask Monte Kiffin, Bill Callahan, and maybe even Rod Marinelli as to how that feels.
Such is not the case with Scott Linehan. While the Cowboys say they “mutually parted ways” with the former OC, they fired him, and that’s indicative that things reached a point where that was necessary.
